A distributed coupled atmosphere–wave–ocean model for typhoon wave numerical simulation

Abstract

A distributed coupled framework system was developed. The framework consists of atmosphere model (MM5), ocean model (Princeton Ocean Model), wave model (WW3) and a coupled programme (coupled model). The coupled programme controls atmosphere–wave–ocean model calculations and data exchanges. The impact of air–sea–wave interactions was considered to examine the validity and performance of this coupled model. Two typical typhoon cases Vongfong (No. 0214) and Rananim (No. 0414) were modelled to examine the wave simulation validity in the China Seas. The coupled model can obviously improve the precision of the significant wave height when compared with the uncoupled run.
