Postdoctoral fellows
2021-Present: Dr. Zhifeng Yang
Education
B.S., Atmospheric Sciences, Lanzhou University, China
M.S., Meteorology, University of Nebraska, Lincoln, US
Ph.D., Atmospheric Physics, University of Maryland Baltimore County, Baltimore, US
Research Interests
His research interests focus on the air quality (wildfire related) and planetary boundary layer meteorology. The research tools employed are weather modeling (WRF, WRF-Chem) and data assimilation. The current research project is to assimilate the PECAN field campaign lidar moisture observations. With the help of models and observations, it is possible to study the extreme weather and precipitation. The observations from radiosonde, microwave radiometer, ALVICE lidar measurements are used to improve the weather model forecast.
