| 摘 要： | 对１９６１—１９９０年（部分资料到１９９４年）期间在南沙海域的观测资料，进行了统计分析，其结果表明：在ＥＮＳＯ发生的当年，南沙海域的海平面气压呈正距平，年降水量明显偏少，热带气旋活动的日数一般偏少；在历次ＥＮＳＯ过程中，南沙海域的总云量与ＳＯＩ的变化趋势基本一致。该项工作有助于了解ＥＮＳＯ对南沙海域天气气候的综合影响和提高天气预报的质量

| Abstract: | Based on the data observed from 1961 to 1990 (some data to 1994),this paper statistically analyzes the effect of ENSO on atmospheric pressure,total cloud cover,precipitation and numbers of tropical storm in Nansha waters ,and discussed the comprehersive effect of ENSO on the climatic state in Nansha.The results show:(1)in the year when ENSO occurring,the atmospheric pressure in Nansha waters is all positive anomaly for many years accounting;(2)the total cloud cover anomaly in Nansha waters is basically identical with the variation trend of SOI in each ENSO duration;(3)the annual precipitation in Nansha waters is obviously little in the year when ENSO occurring (or next year);(4)the effect of ENSO on the annual numbers of tropic cyclone presents ,there is fewer in the year when El Nino event occurring,more tropic cyclones next year and mainly occurring in autumn and winter. |
