The Air-Sea Exchange Difference of the Warm Pool of the Western Pacific Under the Different Weather Systems
西太平洋暖池在不同天气系统下的海气交换差异

This article attempts to analyze the large-scale heat and moisture budgets in the equatorial western Pacific using observation data during TOGA-COARE and the daily grid data from the National Meteorological Center of China (NMCC). In this study, the detail physical parameters of the air-sea exchange in different weather systems are analyzed. Under strong convection conditions, the heating ratio, drying ratio and other parameters, such as the vertical velocity and divergence, etc., are stronger than those under other conditions. The reason could be the release of the latent heat in the condensation precipitation. Nevertheless, in westerly outbreak system, the heating ratio is as much as that of the stable weather system, the drying ratio is the least (negative) among the weather systems. Both the surface sensible and the evaporation heat flux are the strongest in the westerly outbreak system which causes a vapor source in the lower layer of atmosphere.
