采用合成分析和相关分析等方法讨论了季节转换时期 ( 4～ 6月 )黑潮地区海温异常对南海夏季风爆发时间和西太平洋副高位置与强度的影响。数值模拟结果进一步表明 ,该地区海温正异常将导致西太平洋副高位置偏南 ,强度偏强 ,南海夏季风建立较晚 ,强度偏弱 ,江淮流域偏涝 ;反之亦然。 The effects of the SST anomaly in the Kuroshio area during the period of seasonal transition (April-June) on the onset time of the South China Sea summer monsoon and the locations and intensities of the western Pacific subtropical high are discussed using the methods of synthetic analysis and correlation analysis. The numerical simulation further shows that the anomalous SST anomalies in the region will lead to the southwest subtropical high in the western Pacific, with stronger intensity, later onset of the South China Sea summer monsoon, weaker intensity and floods in the Yangtze-Huaihe River basin, and vice versa.
