1961—2000年中国降水与气温变化的关系分析

Analysis on Relationship Between Precipitation and Temperature Variation in China from 1961 to 2000

以1961—2000年我国551个站的气温和降水候资料为基础,采用SVD方法分析我国不同季节气温和降水的分布特征。结果表明:春季新疆和黑龙江的降水与春季气温的年际变化呈显著正相关性,春季北疆、内蒙古和黑龙江的降水与夏、秋和冬季气温的年际变化呈显著负相关性,夏季北疆降水与夏季气温的年际变化呈显著正相关性,冬季北疆、西藏、山东半岛和黑龙江降水与降水的第一模态时间系数的年际变化呈显著负相关性。我国春季降水与春、夏气温有显著的异性相关关系,冬季降水与冬季气温存在显著的同性相关关系。

Based on the temperature and precipitation data of 551 stations from 1961 to 2000,the distribution characteristics of temperature and precipitation in different seasons of China were researched by using SVD method.Resuhs showed that the relationship between interannual variation of temperature and precipitation in Xinjiang and Heilongjiang areas in spring was significantly positive, the interannual variation of precipitation in spring and temperature in summer,autumn and winter in Northern Xinjiang,lnner Mongolia and Heilongjiang was significantly negative.The relationship between interannual variation of precipitation in summer and temperature in Northern Xiujiang in summer was significantly positive.The relationship between the interannual variation of precipitation and time coefficient of the first modal of precipitation was significantly negative in Northern Xinjiang, Tibet, Shandong Peninsula and Heilongjiang area in winter.The relationship between precipitation in spring and the temperature in spring and summer in China was significantly dissimilar, and the relationship between precipitation and the temperature in China in winter was isotropic.
