| 摘 要： | 利用中国科学院风沙科学观测场2005年全年的近地层观测资料,研究了腾格里沙漠地区风向、风速玫瑰图,风速廓线,温度廓线和湿度廓线的月变化及季节变化规律,揭示了腾格里沙漠地区近地层风、温、湿要素特征。风速廓线的四季变化明显,夏季风速最大,其次为春季\,秋季,冬季风速最小。温度、湿度廓线也存在着明显的月变化:1月最冷,7月最热;10月湿度最大,4月湿度最小,四季中春季最干。

| Abstract: | Using the data collected at the Sand Drift Observation Station of Chinese Academy of Sciences in 2005, the monthly and seasonal change of rose diagram of wind speed and direction, wind velocity,temperature and humidity profiles near the surface layer are analyzed in detail. These characteristics in the Tengger Desert are made public accordingly. The monthly change of temperature and humidity profiles is also very obvious: the value of temperature in July is greatest, and least in Jan., and the humidity in Oct. is greatest, and least in April, the humidity in the Spring is least in one year. |
