Description:</span></p>
<p class="MsoNormal" style="margin-bottom:0.0001pt"><span style="font-family:"Times New Roman"">During geomagnetic disturbances, large changes</span><span style="font-size:10pt;font-family:Times"> 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.</span></p>
