Sensitivity of Upper Atmosphere to Different Characteristics of Flow Bursts in the Auroral Zone.Meso-scale plasma convection and particle precipitation could be significant momentum and energy sources for the ionosphere-thermosphere (I-T) system.  Following our previous work on the I-T response to a typical midnight flow burst, flow bursts with different characteristics (lifetime, size, and speed) have been examined systematically with Global Ionosphere-Thermosphere Model (GITM) simulations in this study.
