新疆北部夏季降水与海温异常的关系

 利用1960—2004年新疆北部36个气象站月降水资料和美国国家气候数据中心重建的1960—2004年全球2°×2°月平均海洋表面温度资料，研究了新疆北部夏季降水与海温异常的关系。研究表明，新疆北部夏季降水变化与ENSO事件关系不密切，而与前期冬末—春季的5个海温敏感区密切联系，这5个海温敏感区分别为北印度洋、西太平洋暖池及黑潮区、热带中东太平洋、北大西洋和热带大西洋。前期春季海温异常与新疆北部夏季降水变化联系最显著，表现为显著正相关关系。研究为预测新疆北部夏季降水提供了有益的因子。

Relationship Between Summer Precipitation in Northern Xinjiang and Sea Surface Temperature Anomalies

The relationship between the summer precipitation in northern Xinjiang and sea surface temperature was investigated using monthly precipitation data during 1960—2004 of 36 meteorological stations in northern Xinjiang and monthly mean sea surface temperature data during 1960 2004 reconstructed by NCEP/NCAR. The results were as follows. Summer precipitation anomaly in northern Xinjiang didn't relate to ENSO. Summer precipitation anomaly in northern Xinjiang was remarkably sensible to sea surface temperature anomaly in last winter and spring in 5 sea areas which were northern Indian Ocean (20° S—20° N, 60°—110° E), western Pacific warm pool and Kuroshio extent (0°—30° N, 110°—150° E), tropical middle-eastern Pacific (5° S—5° N, 80°—150° W), northern Atlantic (30°—50° N, 20°—60° W)and tropical Atlantic (0°—20° N, 20°—60° W). There is a prominently positive correlation between summer precipitation in northern Xinjiang and spring sea surface temperature anomaly in the 5 sea areas, and it can be used for prediction of summer precipitation in northern Xinjiang.
