IMPROVED WESTERN NORTH PACIFIC TROPICALCYCLONE INTENSITY AND STRUCTURE PREDICTIONS FROM HIMAWARI-8 DATASETS
Abstract
Funds are provided to conduct research exists using observations from the newly-launched Japanese Himawari-8 geostationary satellite Advanced Himawari Imager (AHI). This platform has the capability for continuous imagery over the full disk (at 10-minute intervals), including derived quantities such as atmospheric motion vectors (AMVs). A dynamic initialization in a triple-nested COAMPS-TC model is proposed to fully utilize the high spatial and temporal resolution of the Himawari-8 AMVs. The SAMURAI technique will be used to analyze the wind speed differences between the COAMPS-TC model and the AMVs, which are the increments necessary for the dynamic initialization. The objective is to develop a coupled SAMURAI/dynamic initialization code to demonstrate the impacts of the set of AMVs on the initial conditions and the subsequent 120-h COAMPS-TC forecasts of the track, structure, and intensity. The improved mass-wind balance from the dynamic initialization is expected to ameliorate the initial vortex spin-down problem in COAMPS-TC.
