Title: "Significance of Meso-scale Structures to the Ionosphere/Thermosphere"

Abstract: A recent significant change in our understanding of the ionosphere-thermosphere system is the frequent driving by dynamic meso-scale structures (50 km - 500 km) that couple to the magnetosphere in the polar cap region, the dayside cusp and along auroral oval and sub-auroral magnetic field lines. These structures play a critical role in Space Weather dynamics, interacting with the more slowly changing, large-scale structure that is more directly driven by interaction with the solar wind. The Global Ionosphere Thermosphere Model (GITM), a self-consistent non-hydrostatic model in the upper atmosphere with a flexible resolution, is suitable for studying transient meso-scale phenomena. To improve the description of meso-scale structures in geomagnetic forcing and to evaluate the influence of such structures on the global dynamics of the upper atmosphere, various data and models are utilized to investigate the variations of energy inputs in the cusp, sub-auroral regions and within flow bursts, and their influences on the coupled thermosphere-ionosphere system. 

Biography: Yue Deng is a Professor in the Department of Physics at the University of Texas at Arlington. She received her BS and MS degrees at the Peking University in 1997 and 2001, and her PhD degree at the University of Michigan at Ann Arbor in 2006. She is the co-developer of the first global non-hydrostatic model in the upper atmosphere, Global Ionosphere Thermosphere Model (GITM). Her main research interest is the coupling between ionosphere and thermosphere under different geospace conditions. Dr. Deng was awarded the National Science Foundation (NSF) CAREER award and American Physical Society (APS) Robert S. Hyer Research Award. Her research is supported by NSF, NASA and Air Force Office for Scientific Research (AFOSR). She is serving on the National Academy of Sciences (NAS) Committee on Solar and Space Physics (CSSP) and CEDAR Science Steering Committee (CSSC).
