| 摘 要： | 利用1998～2007年13个等压面的探空资料,对全国五个区域高空温度、相对湿度的年平均和季节平均分布特征进行了分析.结果表明t五个区域高空,白天年平均温度和相对湿度随高度增加的变化趋势与夜晚的变化趋势相似；年平均温度随高度增加而减小,在100 hPa附近降到最低值后随高度增加开始增大；年平均相对湿度随高度增加而减小；年平均高空温度和相对湿度具有明显的南北差异；四季五个区域高空平均温度和相对湿度与年平均的变化趋势相似,尤其是秋季.

| Abstract: | Using the radio sounding data during 1998~2007,the distribution characteristics of annual and seasonal mean temperature,relative humidity of upper air of the five areas in China were analyzed for 13 heights.The results show that the trends of annual mean temperature and relative humidity of upper air of the five areas in China in daytime are similar to the trends at night as the height increasing.The annual mean temperature of the five areas drops with height up to 100 hPa,where they reach the minimum,then increase with height.The annual mean relative humidity of the five areas drops with the height.Annual mean temperature and relative humidity show obvious difference between the south and north of China.As the height increase,the trends of seasonal mean temperature and relative humidity are similar to annual mean, especially the trends of autumn. |
