| 摘 要： | 用太平洋区域30a逐月混合层厚度(dml)及浅层海温(Ts)距平资料,分析了20°S以北太平洋区域dml年际变率的地理分布和季节变化,得到两个纬向dml高变率带,它们分别位于北太平洋(45°N附近)和赤道中、西太平洋。重点分析了赤道太平洋dml高变率带,并对其上混合层气候位置、dml年际异常与ElNino事件关系及伴随强ElNino事件的dml正异常东传等作了初步分析。

| 关 键 词： | 太平洋区域 混合层厚度(dml) 年际异常 ElNino事件 |

| Abstract: | Monthly mean anomaly data(1969-1998) of mixed layer depth(dml) and upper ocean temperature(Ts) are used to analyze the geographic distribution and the seasonal variation in interannual variability of dml in the Pacific.Two largest interannual variability zones of dml are found in the high latitude area in the North Pacific and in the central western equatorial Pacific.The latter is primarily concerned.The climatic location of dml,the correlation between dml anomalies and El Nino events,and the eastward propagation of positive dml anomalies along the equator preliminarily accompanied with a strong El Nino event are analyzed. |
