中文摘要：

将一种用于全球气候模式的海洋湍流参数化方案引入到区域气候模式RegCM4.3中,分别使用两种方案进行气候模拟.分析对比了1996-2009年,两种方案对中国夏季风场、降水量等模拟结果的影响,并与欧洲中期数值预报中心的再分析资料、站点观测降水资料进行了对比分析.结果表明,新方案对东亚夏季西南季风和东南季风的模拟效果有所改善,并提高了中国夏季降水的模拟效果.

英文摘要：

A sea surface turbulent fluxes parameterization scheme was here introduced, which has been widely used in global climate models, into the regional climate model RegCM4.3. Climate simulation using RegCM4.3 was performed according to the original parameterization scheme and the new scheme for sea sur- face turbulent fluxes respectively. We compared the impact of these two parameterizations on the simulation of wind field and summer precipitation in China from 1996 to 2009 and the simulation results were compared fur- ther with European centre for medium-range weather forecasts reanalysis data as well as site-observed precipi- tation data. Conclusions have been drawn that the new scheme can improve the simulation of southeast and southwest summer monsoon of East Asia and the simulation effect of summer precipitation is enhanced.
