During geomagnetic storms, the energy deposited at high latitudes into the Earth’s upper atmosphere can increase significantly, leading to large changes in thermospheric winds, temperature, and composition. High-latitude electric fields promptly penetrate to low latitudes. Plasmasphere erodes, then slowly and unevenly refills. These dynamics catalyze field-aligned plasma flows that tightly couple the magnetosphere-ionosphere-thermosphere (MIT) system. Understanding the coupled MIT system is critical for advancing geospace science, improving space weather prediction, and safeguarding technological systems. This session is dedicated to studying the response of the coupled MIT system to changing levels of geomagnetic activity. We invite synergistic studies combining observations and simulations, studies using data from active experiments (e.g., ground- and space-based radio sounding) and naturally occurring plasma wave phenomena (e.g., lightning-generated whistlers), and data assimilation using machine learning techniques to address various aspects of the response of the coupled MIT system to geomagnetic disturbances and physical processes that drive them.
