Professional Interests

Dr. Hui Christophersen has scientific interests in data assimilation and satellite meteorology and their applications in tropical cyclone analyses and forecasts. She is also interested in exploring different observation sampling strategies and/or advanced data assimilation techniques to improve TC prediction using Observing System Experiments (OSEs) and the Observing System Simulation Experiments (OSSEs). Hui graduated from Florida State University with a Ph.D in Meteorology in May 2015. She also holds a M.S. in Applied Mathematics.

Hui works as a member in the data assimilation team and the OSSE team at HRD through the Cooperative Institute for Marine and Atmospheric Studies (CIMAS). She works with HRD scientists to investigate the impacts of unmanned aircraft systems, such as the Global Hawk, in numerical modeling and data assimilation for high-impact weather predictions through studies using OSEs with unmanned observations collected during prototype operational field missions and the OSSEs based on expected/hypothetical unmanned observing capabilities. She also actively carries out research in aircraft observation simulation, gravity wave simulation, and accessing the impact of assimilating the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) radiances and retrievals on TC predictions.
