Effects of Magnetospheric Lobe Cell Convection on Dayside Upper Thermospheric Winds at High Latitudes

Average ionospheric potential and DMSP F-16 ion drift observations
Tuesday, October 4, 2016

This paper investigates a possible physical mechanism of the observed dayside high-latitude upper thermospheric wind using numerical simulations from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model.
