Nonlinear dynamics allow small variations to grow to structures of up to Earth radii in scale, resulting in significant spatial and temporal variations in dayside plasma properties. Impinging on the magnetopause these structures may facilitate/inhibit magnetic reconnection. Localized magnetopause indentations caused, e.g., by impacts of magnetosheath high-speed jets can drive surface waves and/or low frequency compressional waves within the dayside magnetosphere. These waves can excite field-line resonances, which modify the drift paths of radiation belt electrons resulting in belt depletion through magnetopause shadowing. Extreme transients like foreshock bubbles cause drastic global scale disturbances in the whole magnetosphere-ionosphere system.<br /> <br /> <br /> [[Image:figure_1.png|thumb|upright=5.0|center|From left -&gt; right: 1. Statistical maps of dayside THEMIS magnetosheath observations between 2008 - 2015 binned onto a 0.5x0.5 Re grid on the equatorial plane.

Understanding these cross-scale coupling processes is crucial in the development and validation of models which aim to accurately and reliably characterize and predict the solar wind–magnetosphere coupling.'''<br /> <br /> <br /> =====Goals &amp; Deliverables=====<br /> <br /> <br /> [[Image:goals_and_deliverables.png|thumb|upright=3.0|left]]<br /> <br /> Broad goals of the focus group are to contribute to the understanding of (including but not limited to):<br /> *Bow shock and foreshock dynamics: particle acceleration in foreshock transients; effect of foreshock transients on bow shock structure and their transmission downstream<br /> *Magnetosheath: propagation of meso-scale variations such as high speed jets and filamentary density structures; reconnection in turbulence; waves generated by instabilities and FTEs<br /> *Response of magnetopause processes to upstream variations: reconnection, surface waves, and Kelvin-Helmholtz vortices<br /> *Response of the dayside inner-magnetosphere: excitation of waves; radiation belt effects<br /> <br /> <br /> The deliverables include:<br /> <br /> *Database of spacecraft conjunctions under different solar wind conditions providing both the coverage and the suitable observational data products (fields, particle distribution functions) for validation of current and future global kinetic models.<br /> *Modelling challenge: Events Comparison of different models with multi-point observations from MMSera events chosen by the community. The results will put the novel observations into global context.<br /> *Modelling challenge: Statistics Dayside dynamics in 2D and 3D kinetic and MHD models under different upstream conditions (IMF angle, solar wind velocity) and season (dipole tilt). The results will be compared with observational statistics. This challenge will reveal how similar/different the results are for the different approximations, and point ways to improve future models.<br /> <br /> <br /> =====Expected Activities=====<br /> During the first years we will have coordinated activities with the Transients FG and the Reconnection FG on linking local, conjugate dayside observations to global dynamics via simulations. In the run-up to the MMS extended-configuration dayside season we will discuss optimal data acquisition strategies, informed by numerical models, joint with HSO activities. In 2018 we will collect the first observations from this phase.<br /> The two modeling challenges will run in parallel. The common starting point is a single, short time interval with constant solar wind conditions matching an observed spacecraft conjunction. Towards the end of the FG the Events challenge will proceed to actual storms and solar wind discontinuities. The Statistics challenge has more emphasis on model-model comparisons, and the in situ validation will be against observational statistics, first from THEMIS/Cluster and then from MMS.<br /> As a part of the modeling challenges we will agree on a road map to make the data from kinetic models available and accessible to the community. Towards 2020 we will discuss how to achieve kinetic physics in operational space weather models.<br /> <br /> '''You can download the actual proposal''' [[Media:DaysideKinetic.pdf|here]]<br /> <br /> <br /> ==Workshops==<br /> Here you can find summaries of previous workshops and planned session for future ones.

<p>Andrew.dimmock: </p> <hr /> <div>==Virtual GEM Summer Workshop 2020==<br /> <br /> Due to the ongoing COVID-19 pandemic, the 2020 Summer GEM workshop was held virtually over Zoom and Slack. The Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction focus group held 2 concurrent sessions on Thursday between 1:00pm-2:30pm and 3:00pm-4:30pm ET. The sessions were well attended with a peak audience of 82 participants. Short summaries of the sessions are provided below.<br /> <br /> ===Session 1: Thursday Concurrent Session 1 1:00pm-2:30pm ET===<br /> Daniel Graham (IRF Uppsala, Sweden) provided an overview of the MMS science being conducted by the IRF Uppsala team. A wide variety of topics were discussed such as magnetic reconnection, whistler generation at quasi-perpendicular shocks, bow shock ion reflection, and electrostatic waves at the magnetopause.<br /> <br /> Chih-ping Wang (UCLA, USA) presented a THEMIS-DMSP conjunction event to show magnetospheric processes responsible for the variations of soft electron precipitation. As shown by the three THEMIS probes, the large precipitation variations observed by DMSP were contributed by strong spatial and temporal variations in the plasma sheet cold electron fluxes, waves of three different modes (kinetic Alfven waves, ECH, and chorus waves), and upward field-aligned currents.<br /> <br /> Brian Walsh (Boston University, USA) discussed the upcoming LEXI mission designed to place an X-ray telescope on the lunar surface to generate images of the dayside magnetopause. The project is part of the NASA Lunar Surface and Technology Payloads (LSITP) program and is scheduled for lunar deployment in 2022<br /> <br /> Hyunju Connor (University of Alaska Fairbanks, USA) estimated neutral densities near the subsolar magnetopause using XMM-Newton X-ray observations and OpenGGCM global MHD model. The estimated neutral densities are higher during solar minimum than solar maximum, suggesting that photoionization plays an important role in this outer exosphere region.<br /> <br /> Martin Archer (Queen Mary University of London, UK) discussed parameterizing the steepening of foreshock ULF waves into shocklets and SLAMS. He introduced an independent and dimensionless quantitative measure of wave steepening based on the tail weight of dB/dt, showing this well orders the phenomena and correlates highly to ΔB/B allowing future quantitative comparisons of steepening under different upstream conditions and at different environments across the solar system. <br /> <br /> Yuxi Chen, (University of Michigan, USA) presented the MHD-EPIC simulation results of the southward IMF challenge event, compared the simulation magnetic field and plasma properties with the MMS observations, and studied the evolution of the X-lines at the magnetopause.<br /> <br /> ===Session 2: Thursday Concurrent Session 1 3:00pm-4:30pm ET===<br /> Hyomin Kim (New Jersey Institute of Technology, USA) presented ionospheric signatures at interhemispheric conjugate locations in response to hot flow anomalies (HFAs) observed by the MMS spacecraft near the bow shock. A series of HFA events occurred over the course of less than an hour, of which the ground responses were shown as traveling convection vortices (TCV), EMIC waves, and ionospheric convection flow changes/enhancements with approximately 8 min delays. Solar wind and geomagnetic activities did not appear to provide favorable conditions for such dynamic signatures on the ground. <br /> <br /> Terry Liu (UCLA, USA) presented case studies that show that magnetosheath jet-driven bow waves can accelerate ions and electrons. From a statistical study, they showed that large solar wind dynamic pressure, large plasma beta (low magnetic pressure), and large Alfven Mach number favor the formation of jet-driven bow waves. They also showed that it is common for them to accelerate particles indicating their potential contribution to the particle acceleration at the parent shock.<br /> <br /> David Sibeck (NASA/GSFC, USA) presented observations from a time interval when the THEMIS spacecraft straddled the post-noon bow shock. The observations confirm the direct transmission of correlated foreshock cavity density and magnetic field strength variations into the magnetosheath.<br /> <br /> Sun-Hee Lee (NASA/GSFC, USA) used Magnetospheric Multiscale (MMS) spacecraft observations to identify 23 FBs from September 2015 to January 2020. Ion intensities at energies for 5.2 to 37.4 keV are generally greater during than before or after the events, suggesting that FBs can accelerate particles to these energies. <br /> <br /> Ahmad Lalti, (IRF Uppsala, Sweden) presented in the generation of whistler waves upstream of quasi-perpendicular shocks.<br /> <br /> Adam Michael (Applied Physics Laboratory, USA) discussed MMS observations of periodic low frequency waves at the dawn-flank, high-latitude boundary layer on February 25, 2016, likely generated by the Kelvin-Helmholtz instability. With the global MHD magnetosphere model, GAMERA, a reinvention of the high-heritage LFM code, they show that despite the pristine slow wind impacting the magnetosphere, the high-latitude boundary layer is unstable to KHI. The waves within the global MHD model are consistent with MMS observations and occur where the IMF direction causes the draped field to be perpendicular to the flow velocity.</div>

Nonlinear dynamics allow small variations to grow to structures of up to Earth radii in scale, resulting in significant spatial and temporal variations in dayside plasma properties. Impinging on the magnetopause these structures may facilitate/inhibit magnetic reconnection. Localized magnetopause indentations caused, e.g., by impacts of magnetosheath high-speed jets can drive surface waves and/or low frequency compressional waves within the dayside magnetosphere. These waves can excite field-line resonances, which modify the drift paths of radiation belt electrons resulting in belt depletion through magnetopause shadowing. Extreme transients like foreshock bubbles cause drastic global scale disturbances in the whole magnetosphere-ionosphere system.<br /> <br /> <br /> [[Image:figure_1.png|thumb|upright=5.0|center|From left -&gt; right: 1.

The results will put the novel observations into global context.<br /> *Modelling challenge: Statistics Dayside dynamics in 2D and 3D kinetic and MHD models under different upstream conditions (IMF angle, solar wind velocity) and season (dipole tilt).

In the run-up to the MMS extended-configuration dayside season we will discuss optimal data acquisition strategies, informed by numerical models, joint with HSO activities. In 2018 we will collect the first observations from this phase.<br /> The two modeling challenges will run in parallel. The common starting point is a single, short time interval with constant solar wind conditions matching an observed spacecraft conjunction. Towards the end of the FG the Events challenge will proceed to actual storms and solar wind discontinuities. The Statistics challenge has more emphasis on model-model comparisons, and the in situ validation will be against observational statistics, first from THEMIS/Cluster and then from MMS.<br /> As a part of the modeling challenges we will agree on a road map to make the data from kinetic models available and accessible to the community. Towards 2020 we will discuss how to achieve kinetic physics in operational space weather models.<br /> <br /> '''You can download the actual proposal''' [[Media:DaysideKinetic.pdf|here]]<br /> <br /> <br /> ==Workshops==<br /> Here you can find summaries of previous workshops and planned session for future ones.

<p>Andrew.dimmock: </p> <hr /> <div>==GEM Summer Workshop 2019: session summaries==<br /> <br /> The 2019 GEM summer workshop was held between June 24-28, 2018 at the Eldorado Hotel in Santa Fe, NM. We held four sessions in the Summer 2019 Workshop.<br /> <br /> - [[2019 Summer Workshop : Session schedule]]<br /> <br /> ===UMEA/Dayside Kinetics/IHMIC joint session===<br /> The theme of the session was to consider the ULF wave response to dayside transients with different temporal/spatial scales and asymmetries. The guest convener Tom Elsden first introduced the session and the questions posed to the participants:<br /> * How are ULF wave properties affected by asymmetries in the upstream driver? What modelling/observational work is required to answer this?<br /> * Further, how then do the resulting ULF wave asymmetries impact the M-I system?<br /> * How does the 3D structure of dayside kinetic phenomena (e.g., spatial scale of magnetopause disturbance, location relative to magnetic equator) affect the ULF response in different hemispheres/LT sectors?<br /> * Can we use magnetospheric observations to determine the size (localized vs global) of a dayside transient? Is the response well-enough understood?<br /> <br /> Ferdinand Plaschke gave an invited overview of dayside transients generating ULF waves inside the magnetosphere: solar wind variations, foreshock phenomena (e.g., hot flow anomalies, foreshock bubbles, foreshock waves), magnetosheath jets and mirror modes, as well as magnetopause processes (e.g., flux transfer events and the Kelvin-Helmholtz-instability). Magnetosheath jets have recently become the focus of scientific interest as they occur often, have significant impact, and act as long-range link between the bow shock and the magnetopause, ultimately connecting foreshock processes with effect observable on ground.<br /> <br /> Tom Elsden discussed recent results from a newly developed 3D MHD code looking at ULF wave excitation in the outer magnetosphere. He showed the importance of understanding the normal waveguide modes of the system in order to predict 3D FLR structure/location, as well as commenting on future uses of the code to study ULF waves driven by local magnetopause disturbances.<br /> <br /> Boyi Wang presented recent observations of the role of foreshock/magnetosheath disturbances in triggering magnetospheric Pc5 ULF waves. Significant magnetosheath disturbance was observed with a foreshock transient in the pre-noon sector. The disturbance further triggers a series of Pc5 ULF wave and the wave can propagate from dayside all the way to midnight.<br /> <br /> Bob Lysak and collaborators have investigated quarter-wave field line resonances, which are observed when one footpoint of the field line is in sunlight and the other is in darkness, using a numerical simulation of ULF waves in the inner magnetosphere. They have found that such quarter-wave emissions excited by a shock-like impulse at the magnetopause, can occur on field lines within the plasmasphere near the terminator, consistent with the observations of Obana et al. (2015) that showed the resonant frequency nearly doubling when the magnetometer observing the wave passed from darkness into sunlight.<br /> <br /> Xueling Shi presented Conjugate Observations of ULF Waves during an Extended Period of Radial IMF. The ULF waves were observed over a wide range of dayside local times and outer magnetospheric L shells. The upstream ion foreshock during an extended period of radial IMF probably plays an important role in providing a seed perturbation for the growth of the KH instability which generates the dayside ULF waves.<br /> <br /> Finally, UMEA Focus Group co-chair Michael Hartinger reviewed discussions from previous GEM Workshops related to the session theme. While numerous past GEM presentations indicate a relationship between dayside kinetic phenomena and magnetospheric ULF waves, there are unresolved questions concerning the effectiveness of different transients in driving waves. Statistical studies and modeling efforts are needed to determine how transients related to different spatial distributions and speeds on the magnetopause affect wave activity.<br /> <br /> ===Dayside Kinetics/Bow Shock joint session===<br /> <br /> The theme of the session was to discuss new studies of key kinetic processes which are important to both the bow shock and dayside region. The main topics included transmission of transients/waves through the shock, impact of shock processes on the downstream region, and the formation of shock-like structures in different dayside regions.<br /> <br /> Ian Cohen presented MMS data from 8 Jan 2018, when it encountered its only interplanetary shock to-date, observing electron heating, near-specularly reflected ions, and apparent significant non-linear electric field structures. The high-resolution particle and field measurements enabled multiple approaches to calculate the cross-shock potential for this marginally supercritical shock.<br /> <br /> Xin An used particle-in-cell simulations to reveal the formation process of foreshock transients and to provide clear evidence on the critical role of electric fields in shaping the magnetic field structures, as well as in coupling the energy of hot ions to that of the secondary shock, which is subsequently dissipated through the excitation of magnetosonic waves. They further demonstrated that higher Mach number of the parent shocks favors the formation of the secondary shocks, which will be appealing to consider in particle acceleration of high Mach number astrophysical shocks.<br /> <br /> Yann Pfau-Kempf presented Vlasiator simulation results on the transmission of foreshock ULF waves to the magnetosheath.<br /> <br /> Michael Balikhin showed the first direct observations of quasi-perpendicular bow shock nonstationarity, which was achieved during a Cluster close separation campaign. The main result was that nonstationarity is initiated by electron scale structures within the ramp, agreeing with the gradient catastrophe model, but not those proposed by some numerical PIC simulations.<br /> <br /> Heli Hietala presented global 3D hybrid simulations of magnetosheath jets. The jets identified from the simulation using similar criteria as in spacecraft observations extend from the bow shock into the subsolar magnetosheath and have very irregular shapes.<br /> <br /> Terry Liu’s statistical study using THEMIS shows that high solar wind dynamic pressure, large solar wind plasma beta, and high bow shock Alfven Mach number favor the formation of magnetosheath jet-driven bow waves. Jets with a bow wave have higher probability to have larger particle energies than jets without a bow wave.<br /> <br /> ===Reconnection/Dayside Kinetics joint session===<br /> Magnetic reconnection itself is a key dayside kinetic process and it is closely related to other kinetic processes, including waves and turbulence. The goal of this session was to understand fundamentals of dayside reconnection. The main topics included:<br /> * What are the characteristics of magnetic reconnection on the dayside?<br /> * What role does reconnection play in forming various dayside transients?<br /> * What are the new approaches/opportunities of studying magnetic reconnection?<br /> <br /> Katariina Nykyri presented MMS observational and global simulation results on the generation mechanism of a new kind of magnetic bottle structure with energetic particles of both solar wind and ionospheric origin at the southern dayside magnetospheric boundary layer formed by low latitude reconnection. The center bottle, characterized by weak magnetic field, was filled with high fluxes of 90 degree pitch angle energetic electrons and ions.<br /> <br /> Andrew Dimmock gave an overview of the SMILE Soft X-ray Imager (SXI) which will observe the dayside-magnetosphere interaction in soft X-rays resulting from solar wind charge exchange. The novel new dataset can be used to track the motion of the magnetopause and cusps, making it possible to investigate the fundamental modes of solar wind-magnetosphere interactions.<br /> <br /> Brian Walsh presented an update on the development of the CuPID Cubsat Observatory. The 6U cubesat will image ion dispersions in the cusps to study meso- and macro-scale properties of magnetic reconnection.<br /> <br /> Xuanye Ma compared the Kelvin-Helmholtz (KH) instability in a fluid simulation with test particles with a hybrid simulation. The Hall MHD with test particle and hybrid simulation give almost identical particle mixing rate in the KH instability. Test particle shows the KH instability can form an anisotropic velocity distribution.<br /> <br /> Karlheinz Trattner considered the dynamics of elongated dayside X-lines using MMS observations and the maximum shear model.<br /> Marcos Silveira and collaborators surveyed flux transfer events observed by the MMS mission in the vicinity of the Earth’s magnetopause from Y = -12 to 12RE with a large range of characteristic time and cross-section length. One case of a small-scale flux transfer event with an electron scale structure was presented.<br /> <br /> ===Dayside Kinetics/MMV joint session===<br /> <br /> This session focused on the Dayside Kinetics Southward IMF Challenge. We discussed the progress in comparing observations and modelling results for the event on 2015-11-18 01:50-03:00 UT, featuring an MMS-Geotail magnetopause conjunction with SuperDARN radar observations. Heli Hietala first presented a summary of the Challenge progress so far. We then moved on to new observation-modelling comparisons, in particular of the magnetopause transients (are they due to simple boundary layer motion or more FTE-like).<br /> <br /> Sarah Vines presented an overview of the MMS observations from the Challenge event that were provided for the data-model comparisons (magnetic field and plasma moments in the published LMN system and dB power spectra), and the results of an initial run of the maximum magnetic shear model. Additionally, they discussed low-energy ion composition for this event, particularly the heavy magnetospheric ions (He+, O+) reaching the outer magnetosphere and magnetopause that are energized in the current layer and reconnection exhaust.<br /> <br /> Karlheinz Trattner presented new maximum shear model results for the event and comparison with MMS. According to their analysis, MMS observed a single clean magnetopause crossing bracketed by several boundary layer encounters before and after the crossing. Each boundary layer encounter showed southward accelerated ion beams indicating the presence of an X-line north of the satellites, with no FTE signatures on the southern side of the X-line.<br /> <br /> Zhifang Guo used a three-dimensional global-scale hybrid simulation to study the MMS observations during the event. The location of the magnetopause reconnection, the global distribution of the X-lines, the spatial and temporal variation in reconnection, the electromagnetic power spectra, and the ion velocity distributions were compared with the observations.<br /> <br /> Marcos Silveira compared the MMS observations with Yuxi Chen’s MHD-EPIC results for the challenge event, where the model observed some of the structures in the similar location of MMS3. The simulation reproduces qualitatively the MMS observations of magnetopause transients, suggesting the probes observed edges of possible flux transfer events in the magnetosphere.<br /> <br /> We finished with a discussion on the wrapping up of the Challenge, including JGR-Earth and Space Science Special Issue manuscript coordination.</div>

Nonlinear dynamics allow small variations to grow to structures of up to Earth radii in scale, resulting in significant spatial and temporal variations in dayside plasma properties. Impinging on the magnetopause these structures may facilitate/inhibit magnetic reconnection. Localized magnetopause indentations caused, e.g., by impacts of magnetosheath high-speed jets can drive surface waves and/or low frequency compressional waves within the dayside magnetosphere. These waves can excite field-line resonances, which modify the drift paths of radiation belt electrons resulting in belt depletion through magnetopause shadowing. Extreme transients like foreshock bubbles cause drastic global scale disturbances in the whole magnetosphere-ionosphere system.<br /> <br /> <br /> [[Image:figure_1.png|thumb|upright=5.0|center|From left -&gt; right: 1.

Nonlinear dynamics allow small variations to grow to structures of up to Earth radii in scale, resulting in significant spatial and temporal variations in dayside plasma properties. Impinging on the magnetopause these structures may facilitate/inhibit magnetic reconnection. Localized magnetopause indentations caused, e.g., by impacts of magnetosheath high-speed jets can drive surface waves and/or low frequency compressional waves within the dayside magnetosphere. These waves can excite field-line resonances, which modify the drift paths of radiation belt electrons resulting in belt depletion through magnetopause shadowing. Extreme transients like foreshock bubbles cause drastic global scale disturbances in the whole magnetosphere-ionosphere system.<br /> <br /> <br /> [[Image:figure_1.png|thumb|upright=5.0|center|From left -&gt; right: 1.

Understanding these cross-scale coupling processes is crucial in the development and validation of models which aim to accurately and reliably characterize and predict the solar wind–magnetosphere coupling.'''<br /> <br /> <br /> =====Goals &amp; Deliverables=====<br /> <br /> <br /> [[Image:goals_and_deliverables.png|thumb|upright=3.0|left]]<br /> <br /> Broad goals of the focus group are to contribute to the understanding of (including but not limited to):<br /> *Bow shock and foreshock dynamics: particle acceleration in foreshock transients; effect of foreshock transients on bow shock structure and their transmission downstream<br /> *Magnetosheath: propagation of meso-scale variations such as high speed jets and filamentary density structures; reconnection in turbulence; waves generated by instabilities and FTEs<br /> *Response of magnetopause processes to upstream variations: reconnection, surface waves, and Kelvin-Helmholtz vortices<br /> *Response of the dayside inner-magnetosphere: excitation of waves; radiation belt effects<br /> <br /> <br /> The deliverables include:<br /> <br /> *Database of spacecraft conjunctions under different solar wind conditions providing both the coverage and the suitable observational data products (fields, particle distribution functions) for validation of current and future global kinetic models.<br /> *Modelling challenge: Events Comparison of different models with multi-point observations from MMSera events chosen by the community. The results will put the novel observations into global context.<br /> *Modelling challenge: Statistics Dayside dynamics in 2D and 3D kinetic and MHD models under different upstream conditions (IMF angle, solar wind velocity) and season (dipole tilt). The results will be compared with observational statistics. This challenge will reveal how similar/different the results are for the different approximations, and point ways to improve future models.<br /> <br /> <br /> =====Expected Activities=====<br /> During the first years we will have coordinated activities with the Transients FG and the Reconnection FG on linking local, conjugate dayside observations to global dynamics via simulations. In the run-up to the MMS extended-configuration dayside season we will discuss optimal data acquisition strategies, informed by numerical models, joint with HSO activities. In 2018 we will collect the first observations from this phase.<br /> The two modeling challenges will run in parallel. The common starting point is a single, short time interval with constant solar wind conditions matching an observed spacecraft conjunction. Towards the end of the FG the Events challenge will proceed to actual storms and solar wind discontinuities. The Statistics challenge has more emphasis on model-model comparisons, and the in situ validation will be against observational statistics, first from THEMIS/Cluster and then from MMS.<br /> As a part of the modeling challenges we will agree on a road map to make the data from kinetic models available and accessible to the community. Towards 2020 we will discuss how to achieve kinetic physics in operational space weather models.<br /> <br /> '''You can download the actual proposal''' [[Media:DaysideKinetic.pdf|here]]<br /> <br /> <br /> ==Workshops==<br /> Here you can find summaries of previous workshops and planned session for future ones.

<p>Andrew.dimmock: /* Mini GEM 2018 */</p> <hr /> <div>===Mini GEM 2018===<br /> <br /> The 2018 Mini GEM was held on December 9th, 2018 at the Hilton Alexandria Old Town in Alexandria, Virginia<br /> <br /> == Session 1 GEM challenge event ==<br /> <br /> === Scheduled presentations ===<br /> <br /> Sarah Vines: Sarah talked about the location of the magnetopause given by the Shue model<br /> and the configuration of the X-line given by Trattner’s maximum shear angle model. Both<br /> models are based on solar wind input and the results are consistent with spacecraft<br /> measurements. Sarah also talked about the magnetopause motion, thickness, current density,<br /> shear angle, and the difference in plasma beta across the magnetopause. She identified the<br /> presence of cold ions and calculated the power spectra of the magnetosheath magnetic field.<br /> <br /> Yuxi Chen: Yuxi compared properties of the magnetopause and the magnetosheath of<br /> MHD-EPIC, Hall MHD, and ideal MHD. These models provide similar magnetopause location<br /> and X-line extent, and reconnection jet speeds. But the Hall MHD model produces more<br /> structures/variability at the magnetopause than the MHD-EPIC.<br /> <br /> Jeff Broll: Jeff discussed a way to identify LMN coordinates through performing MVAB and<br /> MDDB in an unsupervised manner.<br /> <br /> Marcos Silveira: Marcos investigated whether the transients seen by MMS spacecraft during<br /> the magnetopause crossing are FTEs. He exemplified classic FTE signatures in aspects of<br /> magnetic field and particle properties and found that none of the seen transients fit into classic<br /> FTEs.<br /> <br /> === Open discussion ===<br /> <br /> Yu Lin: Yu showed global hybrid simulations from ANGIE3D.<br /> <br /> Naritoshi kitamura: Naritoshi presented the dependence of the statistical location of X-line on<br /> dipole tilt (seasons) and IMF Bx. He found that the X-line location can shift by a few Re in the<br /> north-south direction as seasons and IMF Bx change. The challenge event, however, has a<br /> smaller displacement from the equatorial plane than what the dependence suggests.<br /> <br /> '''Discussion topics'''<br /> <br /> - Quantitative metrics are needed to perform model/model and model/data comparisons<br /> and specific entropy could be used as a metric.<br /> <br /> - Coordination is needed between modellers and observers to complete challenge event<br /> studies.<br /> <br /> - For power spectra, it will be more useful to compute the spectral slope rather than<br /> comparing the spectra.<br /> <br /> - The FTE presence and properties should be checked in the model.<br /> <br /> == Session 2: Dayside transients - local vs global effects on the magnetopause ==<br /> <br /> === Scheduled presentations ===<br /> <br /> David Sibeck: David reviewed the impacts of hot flow anomaly (HFA). HFA produces pressure<br /> variations in the magnetosheath, traveling magnetopause waves, and traveling convection<br /> vortices in the ionosphere. In a fortuitous conjunction events, HFA causes a “bulge” of the<br /> magnetopause that is 10-20 Re long in the north-south direction, 2-4 Re in the east-west<br /> direction, and 1-9 Re in the sunward direction.<br /> <br /> Martin Archer: Martin presented two major impacts of high speed jets. One is compressing the<br /> current sheet and triggering magnetic reconnection. One is creating indentation of the<br /> magnetopause. As magnetopause rebounds, a surface wave forms. He notes that the time<br /> scale of indentation/rebounding might be controlled by collective properties of HSJ or<br /> eigenvalues of the magnetopause surface waves. He presents one event where HSJ have a<br /> broad power spectrum in frequency while the magnetopause motion and ULF waves have a<br /> narrow spectrum.<br /> <br /> Xochitl Blanco-Cano: Xochitl discussed how cavitons and spontaneous hot flow anomalies<br /> (SHFAs) can modify the bow shock, magnetosheath and possibly the magnetopause. Vlasiator<br /> simulations have shown that the arrival of SHFAs can cause shock weakening and the<br /> formation of magnetosheath cavities. More work is needed to understand if SHFAs can cause<br /> waves at the magnetopause similar to the ones produced by HFAs.<br /> <br /> === Open discussion ===<br /> <br /> Katarina Nykyri: Katariina presented one event where HSJs likely drive a substorm. This<br /> implies that localized transients (though there might be many in quantity) can have global effect.<br /> <br /> '''Discussion topics'''<br /> <br /> - Does the transient size control the size of response?<br /> <br /> - How do we differentiate between direct and seeding response.</div>

Nonlinear dynamics allow small variations to grow to structures of up to Earth radii in scale, resulting in significant spatial and temporal variations in dayside plasma properties. Impinging on the magnetopause these structures may facilitate/inhibit magnetic reconnection. Localized magnetopause indentations caused, e.g., by impacts of magnetosheath high-speed jets can drive surface waves and/or low frequency compressional waves within the dayside magnetosphere. These waves can excite field-line resonances, which modify the drift paths of radiation belt electrons resulting in belt depletion through magnetopause shadowing. Extreme transients like foreshock bubbles cause drastic global scale disturbances in the whole magnetosphere-ionosphere system.<br /> <br /> <br /> [[Image:figure_1.png|thumb|upright=5.0|center|From left -&gt; right: 1.
