Summary:
A compelling challenge in the study of global ionospheric electrodynamics during geomagnetic storms is to identify and characterize penetration and disturbance dynamo electric fields and their impacts on the behavior of the ionosphere during geomagnetic storms. The objective of this proposed work is to achieve breakthroughs in understanding and quantifying storm-time penetration and dynamo electric fields in the mid-latitude and equatorial ionosphere through comprehensive data analysis and physics-based model simulations. Ionospheric electric fields play a key role in the Sun-Earth connection as they are the result of direct coupling between the solar wind and the magnetosphere/ionosphere system and between thermospheric neutrals and ionospheric plasma. However, many aspects of the fundamentals of storm-time penetration and dynamo electric fields are still not well understood. Recent studies have revealed that penetration electric fields play a much more important role in ionospheric storms than previously thought and that disturbance dynamo electric fields can dominate equatorial electrodynamics for a long period of time (e.g., 20 hours) after a magnetic storm ceases.Performance Year | Reference | Investigation Type | Actions |
