| 摘 要： | 根据实测资料，初步确定南海夏季风平均爆发日期是5月16日(即5月的第4候)，分析了南海中北部次表层水温变化与南海夏季风活动的关系。在1981-2000年期间，偏冷年份有1981、1984、1986、1990和1992年，偏暖年份有1983、1993、1995、1998、1999和2000年，其余年份为正常年。南海夏季风爆发的迟(早)与南海中北部次表层水温持续偏冷(偏暖)现象关系密切；南海中北部次表层水温6—10月异常偏冷(偏暖)时，南海夏季风则提早(推迟)结束，来年南海夏季风推迟(提早)爆发。8-12月西沙水温异常偏冷(偏暖)时，南海夏季风提早(推迟)结束，来年南海夏季风推迟(提早)爆发。 |

| Abstract: | Based on the observed data, the onset date of summer monsoon in the South China Sea was preliminarily confirmed, which is May 16th, and the relationship of the variation of subsurface sea temperature in the north and middle of the South China Sea to the activity of the summer monsoon in the South China Sea was also analyzed. Among the year from 1981 to 2000, 1981, 1984, 1986, 1990, and 1992 are colder years, 1983, 1993, 1995, 1998, 1999, and 2000 are warmer years, and the other years are normal. The results showed that the onset date of summer monsoon is later (or earlier) when the subsurface sea water in the north and middle of the South China Sea becomes colder (or warmer). When the subsurface sea water is abnormally colder (or warmer) in the north and middle of the South China Sea during the period from Jun. to Oct. and in the Xisha Islands sea area during the period from Aug. to Dec., the summer monsoon will end earlier (or later), and next year the onset date of summer monsoon will be later (or earlier). |
