【摘要】 对NCAR/DOE1979-2009年11月份至次年2月份0-10cm及10-200cm两个层次上的土壤温度平均场进行EOF分析显示了我国地温变化可以分为两个阶段:第一阶段在东北、内蒙东北部和西北东部-华北地区有明显的升温趋势,江淮和华南北部地区变化趋势不明显;第二阶段2000年后北方地温偏低但依然存在上升趋势,南方以降温趋势为主。使用全国160各站的5-9月份的汛期降水平均场的资料与冬季地温场特征向量场的时间系数求相关得到了两者相关显著区,进而研究相关区域的月相关关系。发现内蒙古北部及其以北地区的地温变率大值区与我国汛期降水可能有较好的相关关系。更多还原

【Abstract】 Based on the data of monthly mean 0-10cm and 10-200cm soil temperature from November to February over 1979-2009,it has been made that the climatological analysis of China.The results of Empirical Orthogonal Function(EOF) decomposition show that there is obvious temperature-rise trend in northeast china,northwest of inner northeast,Northwest eastern China,while the regional Change of South China and Yangtze-Huaihe RiverValley is not dominant.Throught the Correlation analysis of national 160 stations in the 5-9 flood data of precipitation average field and temperature field’s Time coefficients of characteristic vector field obtained in winter.we found related significant area,and then continued relevant research on Monthly related regional correlation.we confirmed temperature field of Inner Mongolia and the Northern China has a good relationship with precipitation during rainy season in china.更多还原
