Abstract

Abstract:

In this paper, the ocean-atmosphere-wave coupled model, COAWST, was used to conduct two sets of 72hour simulation tests centered over the East China Sea. The impacts of dynamic wave processes on shortterm weather simulation were analyzed by comparing the two tests, one of which considered the dynamic wave processes and the other not. The results revealed that the simulation of sensible and latent heat flux would be enhanced if considering the wave processes. Consequently, wetter and warmer air at the sea surface was detected, leading to lower sea level pressure (SLP) and acceleration on convective activity. The changes of circulation would strengthen the local wetter and warmer difference, which made for the generation of positive feedbacks. The wettest and warmest difference was detected over the northwestern area of the South China Sea along with the Philippine waters. In addition, the difference would decrease with the height, and finally disappear near the 500 hPa height.

Key words: sensitivity analysis, wave progress, COAWST, weather simulation
