| 摘 要： | 本文主要分析了长江中下游梅雨期旱涝(下称旱涝)与南海海温异常及西太平洋副热带高压(下称副高)之间的关系。并初步探讨了前期海温与梅雨期降水及旱涝的关系。 所用海温资料为5°×5°网格点月平均资料,时间从1951—1972年共22年。500hPa的各副高特征指数取自中央气象台长期科出版的资料。我们取武汉、南昌、九江、安庆、合肥、南京和上海等8个站的月平均降水量代表长江中下游地区降水,时间与海温资料对应。取6—7月平均降水量为梅雨期时段的平均降水量,并选取降水距平大于或等于正(负)50mm的1954,1969及1970年和1958,1961,1967及1968年分别作为梅雨期持续旱涝的个例年份。然后计算旱涝年合成的海温场及各要素场。

| Abstract: | Analysis shows that, during 1951-1972, warmer June-July South China Sea surface accords with rainy Mei-Yu season and the West Pacific High extension. It is also found the preceding South China Sea temperature is positively correlated to June-July yangtze rainfall. |
