利用全球海表面温度、海面流速、海平面异常、降雨和海面风场融合及再分析资料,采用相关分析和合成分析统计诊断方法,对1979-2014年发生的东太平洋和中太平洋El Nio事件对黑潮流域的影响进行分析,为黑潮流域及我国东南部气候变化预测提供参考。研究结果表明:前者对海表面温度的影响要比后者强烈,并经历了从降温到升温的效应转换;两者对黑潮流域海流流速的影响整体上呈相反状态,前者对东海PN断面海流流速起减缓作用,而后者对其流速起加速作用;对于黑潮流域的海平面异常,两者均没有明显的规律性影响;前者会引起黑潮流域降水增多,而后者则会引起黑潮流域降水减少。因此,东太平洋和中太平洋El Nio事件对黑潮流域的影响具有明显的差异。 Based on the data of global sea surface temperature, sea surface velocity, sea level anomaly, rainfall and sea surface wind field and reanalysis data, correlation analysis and synthetic analysis of statistical methods were used to analyze the distribution of El Nio in the East Pacific and Central Pacific from 1979 to 2014 The impact of the events on the Kuroshio basin is analyzed to provide reference for the prediction of climate change in the Kuroshio basin and southeastern China. The results show that the former has a stronger influence on the sea surface temperature than the latter, and has undergone the effect conversion from cooling to warming. The impact of the two on the sea current velocity in the Kuroshio basin is in the opposite state as a whole. While the latter accelerates its velocity. For the sea level anomaly in the Kuroshio basin, there is no obvious regularity between the two. The former will cause more precipitation in the Kuroshio basin, while the latter will lead to the Kuroshio basin Decreased precipitation. Therefore, the impacts of El Nio events in the eastern Pacific and the Central Pacific on the Kuroshio basin are significantly different.
