| 摘 要： | 利用EOF、气候突变检测及相关统计方法,分析我国西北地区近37年（1970-2006）冬季地面风速的时空异常,并对近25年（1982-2006）西北干旱区春、夏季地表感热的时空异常变化及其与前期冬季风速的关系进行相应的研究。结果表明：近25年西北地区冬季风速下降趋势显著,20世纪70年代冬季地面风速普遍较大,80年代风...

| Abstract: | In this paper,the spatial distribution and time evolution of wind speed over northwest China in winter in recent 37 years from 1970 to 2006 were analyzed base on EOF analysis,sharp climate change test and correlation analysis.The spatial distribution pattern and temporal variation trend of surface sensible heat in spring and summer as well as the correlation between wind speed in winter and surface sensible heat in next spring and summer in the arid regions of northwest China during the period of 1982-2006 ... |
