Western Pacific Tropical Cyclone Reanalysis With the NRL Atmospheric Variational Data Assimilation System
Abstract
The long-term goal of this project is to improve the prediction of tropical cyclone (TC) genesis, structure and intensity changes through improved initial condition and data assimilation technique. The accurate prediction of TC genesis, structure and intensity changes is critical to Navy missions and civilian activities in coastal areas. Due to sparse observational coverage over the open ocean, a key element of typhoon data assimilation is how to assimilate the satellite products such as Advanced Microwave Sounding Unit (AMSU), AIRS, and SSMIS into the model initial condition. These new satellite products provide high-resolution 3-dimessional temperature and moisture fields and rain rate profiles.
