摘要/Abstract

摘要：

利用海洋-大气-海浪耦合模式COAWST进行了两组以东海区域为中心的72 h模拟试验。通过对比考虑动态海浪过程与未考虑该过程的试验结果，分析动态海浪过程对短期天气模拟的影响。结果表明，考虑动态海浪过程后将增强海表感热、潜热通量的模拟，造成海表大气增暖增湿。这一暖湿差异将促进大气垂向运动的发展，造成海平面低压发展，并进一步影响大气流场的变化，增强局地升温效果，有利于形成正反馈。该暖湿差异在南海西北部与菲律宾海域最为明显，且随高度上升逐渐减弱，至500 hPa高度时差异基本消失。

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
