摘要
首先计算了新疆的北疆、南疆和天山山区的春季降水量与北大西洋海温场的滞后和同期相关系数 ,发现新疆春季降水距平总体上与前一年 7月北大西洋海温距平 (SSTA)场相关最好。然后又采用奇异值分解 (SVD)法找到了两场之间较好的对应分布型 ,并由实测资料得到验证。
The lag and contemporary correlation coefficients are calculated between precipitation in spring in the northern Xinjiang, the southern Xinjiang and the Tianshan Mountain area and SSTA in the Northern Atlantic Ocean. It is found that the relationship between precipitation anomaly in spring in Xinjiang and SSTA in the preceding July in Northern Atlantic Ocean is the best, generally. The SVD method is used to identify corresponding distribution patterns between precipitation fields and SSTA fields, which are verified by real data, finally.
