摘    要:利用统计分析方法,分析了冬季黑潮区域海表温度异常与东亚冬季风的相关关系.及其可能的机制。结果表明:东亚冬季风异常与冬季黑潮区域海温异常有密切的联系。当东亚冬季风偏强时,冬季黑潮区域海温偏低;反之,当东亚冬季风偏弱时,冬季黑潮区域海温则偏高。其过程可能是东亚冬季风异常偏强(弱)造成了黑潮区域1000hPa气温的明显下降(上升)。而由于黑潮区域海温的变化相对较小.使得黑潮区域的海气温差也发生了显著地增大(减小),从而使得该区域的海洋热通量也相应地增多(减少)。这种海洋热通量释放的增多(减少),造成该区域的海温下降(上升)。

关 键 词:黑潮  东亚  冬季风  海温异常

Abstract:Analyzed are the relationship of winter kuroshio region SSTA and East Asian Winter Monsoon (EAWM) and its possible mechanism by the statistical methods. Results indicate that EAWM relates the winter kuroshio SSTA closely, namely, the winter kuroshio SSTA becomes positive (negative) when there is a strong (weak) EAWM. The possible mechanism might be that when there is a strong (weak) EAWM, the 1000hPa air temperature over kuroshio region greatly decreases (increases), along with the SST changed quite a little, resulting in the air-sea difference in temperature becomes larger (smaller) and the ocean heat release increases (decrease), therfore the SST over kuroshio decrease (increases).
Keywords:Kuroshio East Asian Winter monsoon SSTA
