Magnetosphere-Ionosphere-Thermosphere Coupling in the Polar Cap:  Drivers and Impacts II Posters


Session ID#: 7824

Session Description:
The polar cap is a dynamic region of the geospace environment where the magnetosphere, ionosphere, and thermosphere (MIT) combine to give rise to a rich variety of interactions.  For example, there is increasing evidence that energy dissipation and Joule heating of ions and neutrals occur at very high latitudes, and are not restricted to the auroral zones.  Localized maxima in observed Poynting fluxes and neutral densities have been identified in the polar caps at all local times in both hemispheres during periods of high magnetic activity.  These new observations radically revise the current paradigm for the MIT response to magnetic forcing by the solar wind, and may be associated with a variety of polar cap phenomena (e.g., polar cap patches, scintillation).  We solicit presentations of high latitude MIT coupling during all periods of magnetic activity, as well as modeling approaches to high-latitude forcing.
