Summary:
An accurate description of vertical winds in the thermosphere is essential to understand how the upper atmosphere responds to the geomagnetic storms. Even small vertical winds have a significant effect on the atmospheric density, composition, dynamics, electrodynamics and ionosphere because of the large vertical gradients. However, vertical winds have not been observed systematically and the simulations of effects on the upper atmosphere are very limited. Recent observation deployments and modeling developments now permit substantial progress on this problem. Observations from satellites and expanding ground-based networks, such as Fabry-Perot interferometers (FPIs) in Alaska and Brazil, are providing unprecedented coverage for understanding the role of vertical wind dynamics. Developments in first-principles models, such as the non-hydrostatic model, enable significant improvement on vertical wind simulations. Therefore, it is timely to investigate vertical winds and influence on the upper atmosphere through complementary data analysis and model simulations. In this project, the data sets from FPI ground-based observations along with DMSP and CHAMP satellites and the simulations from non-hydrostatic General Circulation Model(GCM) will be used to investigate F-region vertical winds due to different forcings at both high and low latitudes and to characterize their influence on the ionosphere and thermosphere.
