| 摘 要： | 计算了1975～1999年南海夏季风强度指数,针对季风强、弱年进行太平洋至印度洋20℃等温面的深度(温跃层深度)距平场合成分析,得到强、弱季风年温跃层深度距平的4种分布形式.使用历年季风强度指数与各月温跃层深度距平作相关计算,发现孟加拉湾和赤道中太平洋的深度距平与季风强度具有很好的正相关,台湾以东海域呈较高的负相关,可作为季风预测的重要因子.

| Abstract: | The intensity index of the South China Sea (SCS) summer monsoon is calculated from 1975 to 1999. Based on the index of strong monsoon and weak monsoon, the anomaly field of themocline depth in the Pacific Ocean to the India Ocean has been composed. Four distribution patterns have been getten. Calculating the relationship between the intensity index of monsoon and the anomaly of thermocline depth is found that positive correlation is higher in the Bay of Bengal and the centre of the Pacific, and negative correlation is good in the ocean lying east of Taiwan Island. These are important factors of monsoon forecast. |
