| 摘 要： | 分析了秋季黑潮区域海表温度异常与东亚冬季风以及我国冬季气候的关系。结果表明：秋季黑潮区域海温与东亚冬季风指数有明显的正相关关系。当秋季黑潮区域海温偏高时，当年的东亚冬季风指数也偏高，即东亚冬季风偏强；反之，则当秋季黑潮区域海温偏低时，当年的东亚冬季风指数也偏低，即东亚冬季风偏弱；秋季黑潮海温升高，我国东北和华北地区气温上升，其他地区冬季气温降低，华南地区降温幅度最大。江淮流域及华南地区降水量明显减少。

| Abstract: | The relationship of autumn Kuroshio region SSTA with the East Asian winter monsoon and Chinese winter climate is analyzed.Results show that there is a closely relation between the autumn Kuroshio region SSTA and the East Asian winter monsoon index.In the higher(lower) Kuroshio SSTA years,the East Asian winter monsoon is stronger(weaker),the winter temperature increases(decreases) in north and northeast China,and decrease(increase) in the other places;the precipitation decreases (increases) in the Changjiang-Huaihe river valley and south China,especially in south China.The distribution of the 500hPa height fields corresponding to the Kuroshio region SSTA displays a PNA- and EAP-type atmospheric teleconnection,and therefore the Kuroshio region SSTA might influence the up- and down-stream atmosphere through the teleconnection. |
