The satellite-derived Hydro-Estimator and Hydro-Nowcaster for Mesoscale Convective Systems and Landfalling Tropical Systems

摘要

For over two decades, meteorologists at the Satellite Analysis Branch (SAB) of the National Environmental Satellite, Data, and Information Service (NESDIS) have provided manual satellite precipitation estimates as guidance for National Weather Service (NWS) field forecasters during heavy rain and flash flood situations. Scientists at the NESDIS Office of Research and Applications (ORA) have developed a number of tools to automate and streamline the processes of both estimating current precipitation and nowcasting near-term precipitation from satellite data. These tools are discussed and illustrated in this paper.
