Dynamic Diagnostics and Simulations of Typhoons Impinging Taiwan Using High-Resolution Global Model Mpas

Project Details


MPAS (Model for Prediction Across Scales) is a new-generation global nonhydrostaticmodel which allows a convenient higher mesoscale resolution for a specific domain of interest. Wehave employed the 60-15 km variable resolution MPAS to reasonably simulate the 7-day track ofTyphoon Haiyan (2013) which commences from an earlier spin-up stage to the final dissipationstage. We have also used the MPAS to predict the track and rainfall of Typhoon Morakot (2009) incomparison with WRF simulations with three nested domains (45 km, 15 km, 5 km), whichdemonstrates the comparable performance of a regional model captured by MPAS. This project willutilize the 30-6 km high-resolution global model MPAS to predict track and rainfall of typhoonsimpinging Taiwan, e.g., Megi (2016), conduct analyses of vorticity budget and asymmetric vortexdynamics as well as develop the quantitative diagnostics of PV budget on spherical coordinates toassess the influences of various physical processes (e.g., advection, diabatic heating and turbulencefriction) on typhoon translation. The achievements of this project can lead to paper publication andprovides useful references to research and operation institutes.
