| 摘 要： | 分析1961～2001年海南5～7月异常高温频数的气候特征及其影响因子南海海温和北半球500hPa高度场特征，结果表明，5、6月异常高温频数分别存在3馏年和5年左右的显著周期；南海中部海域是影响同期异常高温频数的关键区域；异常高温频数偏多年，欧亚地区500hPa环流特征是中高纬度有阻塞高压存在，西风槽南压，西太平洋副热带高压位置长期偏南、偏西。 |

| Abstract: | The climate characteristics of the occurrence frequency of abnormal high temperature from May to July in Hainan were analyzed, and their influential factors,sea temperature over the South China Sea and the Northern Hemisphere 500 hPa height field,were analyzed. It is indicated that the occurrence frequency of abnormal high temperature had a 3.8-year period in May, but a 5-year period in June; the sea area around the middle South China Sea was the key area influencing the frequency of abnormal high temperature in the corresponding periods. In the abnormal year, the circulation characteristics over the Eurasia Continent at the 500 hPa were the blocking high in the middle latitudes, the southward westerly trough, and the subtropical high over the western Pacific Ocean inclined westward and southward for a long time. |
