SA44A:
Dynamical Response of the Thermosphere and Ionosphere to Geomagnetic Disturbances II


Session ID#: 11154

Session Description:
During geomagnetic disturbances, large changes in thermospheric winds, temperature, and composition occur in response to energy and momentum deposition from the magnetosphere and solar wind. These changes further lead to ionospheric variations in dynamo electric field, electron density and TEC. The nonlinear response of the thermosphere and ionosphere depends on various geophysical conditions, such as season and solar activity, and is still not well understood. This session is dedicated to the study of the dynamical response of the coupled thermosphere and ionosphere to geomagnetic disturbances under different geophysical conditions, with emphasis on thermosphere winds and temperature changes during storms, the effect of these changes on the ionosphere, and the feedback effect of ionospheric variations on the thermosphere. We invite contributions based on observations and simulations to address various aspects of the dynamical response of the coupled thermosphere and ionosphere to geomagnetic disturbances and the physical processes that drive this response.
