All are welcome to attend.

Hurricanes are one of the most dangerous natural disasters as they can produce extremely heavy rainfall, damaging winds, and storm surge. Understanding landfalling hurricane induced rainfall is critical in forecasting the impacts of rainfall and issuing flood warnings. I examined data from Multi-Source Weighted-Ensemble Precipitation (MSWEP) and Tropical Rainfall Measuring Mission (TRMM) in terms of precipitation amount and spatial pattern compared with rain gauge data and stage IV radar data as ground truth. In addition, moisture associated with a hurricane can influence its structure and rainfall production. I investigated moisture variation around hurricanes during intensification and pre-landfall phases.
Guoqian Yan is a doctoral candidate advised by Dr. Corene Matyas in the Department of Geography at University of Florida. She earned both her bachelor’s degree and master’s degree in Geographic Information System (GIS) from Northeast Normal University in China. During her UF study, she earned Certificates in Applied Atmospheric Sciences and Geographic Information Systems. Her research focuses on utilizing GIS techniques, Python, shape metrics and statistical methods to analyze rainfall spatial patterns of hurricanes over the North Atlantic Basin.
