LWS TR&T Focus Teams:
Storm effects on global electrodynamics and middle and low latitude ionosphere
Team Chair: Tim Fuller-Rowell
Target description: Magnetic storms cause large departures of electric field from their
quiet values and large changes in the mid and low latitude ionosphere.
The electric field perturbations cover a broad range of spatial and
temporal scales and strongly affect plasmaspheric erosion and reconfiguration,
Goals and measures of success: The goal of this targeted research is to produce improved understanding and forecasting capabilities of storm electrodynamics from subauroral to equatorial latitudes and their effects on the ionosphere in response to different solar wind and magnetospheric conditions. The forecasting of these storm effects from numerical models will be validated against global electric field and ionospheric measurements, taking into account variations with longitude, season, and solar flux.
Types of solicited investigations: Proposals that address this topic are encouraged to consider storm electrodynamics from a global ionosphericmagnetospheric perspective. The research objectives of proposals will include modeling and empirical investigations that deal with (1) techniques to improve the specification and forecasting of magnetospheric parameters that play fundamental roles in middle and low latitude storm electrodynamics; (2) techniques that substantially enhance the database of global mid and low latitude electric field measurements; (3) the generation of mid-latitude polarization electric fields, their temporal and global spatial dependence, and their relationship to lower latitude storm electrodynamics; and (4) the storm time dependence and global distribution of prompt penetration electric fields from subauroral to equatorial latitudes under different solar, ionospheric, and magnetospheric conditions and their effects on the ionosphere.
