南海表面温度距平对我国夏季风和降水影响的数值试验

A NUMERICAL EXPERIMENT OF SST OVER SOUTH CHINA SEA ON THE SUMMER MONSOON AND PRECIPITATION IN CHINA

我国东部夏季降水不仅与副高脊线的向北推进有关,而且与对流层低层夏季季风向北推进有关。Shukla,在研究印度季风降水量对阿拉伯海域海表温度响应时也指出,对季风环流模拟的真实性直接影响印度季风降水模拟的真实性。本文以观测分析结果为依据。

Based on the observational analysis, a numerical experiment of the SST over South China Sea on the monsoon and precipitation in China is presented by using the 11-layer GCM of U. K. Met. Office. It is shown that the warm SST anomalies over South China Sea have attracting to Indian summer monsoon, and cold anomalies have repelling to the Indian monsoon. The relattions of summer monsoon and rainfall in China with the SST anomalies over south China Sea area are also discussed.
