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).

Specifically, she investigates 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 explores various aspects of cloudy radiance data assimilation (currently working on the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) radiances) to improve tropical cyclone prediction in an ensemble, variational and/or hybrid data assimilation framework. Additionally, she carries out research in aircraft observation simulation and flight-level gravity wave simulation in TCs to better understand TC intensity prediction.

Hui graduated from Florida State University with a Ph.D in Meteorology in May 2015. She also holds a M.S. in Applied Mathematics. She is an active participant in HRD's annual hurricane field campaign.
