Focus Group Topic Description and Science Questions
The main goal of this focus group proposal is to understand the interhemispheric symmetry/asymmetry in geomagnetic fields and its effects on M-I coupling. Observational and modeling studies have shown the interhemispheric differences which are manifested in various signatures, e.g., large-scale current systems, auroral forms, waves, ion upflow, outflow, particle precipitation, high-latitude convection and thermospheric winds. The focus group addresses questions as to how to incorporate interhemispheric differences and their effects on M-I coupling in observations and modeling/simulations. The overarching science questions that this focus group will be addressing are:
- In what aspect does the asymmetry in geomagnetic fields play a role in M-I coupling?
- How are the interhemispheric differences related to solar wind and geomagnetic activities?
- What are interhemispheric differences in storm and substorm signatures, wave activity and particle precipitation? What controls these differences?
- How do interhemispheric differences in ionospheric conductivity affect solar wind coupling to the magnetosphere, ionosphere and thermosphere?
- What are effects of the neutral wind dynamo in the application of Ohm's law to ionosphere-magnetosphere coupling? Does the neutral wind dynamo contribute to the interhemispheric asymmetry in M-I coupling?
