A Statistical Forecast Model for Tropical Cyclone Rainfall and Flood Events for the Hudson River
Tropical Cyclones (TCs) lead to potentially severe coastal flooding through wind surge and also through rainfall-runoff processes. There is growing interest in modeling these processes simultaneously. Here, a statistical approach that can facilitate this process is presented with an application to t...
