Session ID#: 12776

Session Description:
The ionosphere and thermosphere (IT) are very dynamic and strongly coupled over various spatial and time scales during geomagnetic storms. This session focuses on the storm-time response of the IT system at middle and low latitudes: (1) the characteristics of penetration and dynamo electric fields, (2) the occurrence of large-scale disturbances such as ionospheric storms and equatorial spread F, (3) the variations of neutral and ion compositions on the bottomside and topside, (4) storm-produced atmospheric gravity waves and TIDs, (5) the relative contribution of different drivers to the generation of ionospheric disturbances, and (6) the coupling among these processes. We welcome observational, theoretical, and modeling studies that improve our understanding and enable a better forecasting capability of middle- and low-latitude ionospheric disturbances.
