摘要:

利用CFL - 03 边界层风廓线雷达,在塔中开展了边界层风场探测研究,根据2010 年4 月1 日至2010 年11 月30 日连续的边界层风场探测资料,分析了塔克拉玛干沙漠腹地大气边界层850 hPa、700 hPa 和500 hPa 特征层风场时空分布特征。结果表明,塔中地区850 hPa 特征层主导风向为偏东风,风速年变化较小; 700 hPa 特征层风速6 月最大,9月最小,6、8、9 月主导风向为偏东风,其余月份为偏西风。500 hPa 特征层风速9 月最小, 11 月最大; 6、9 月主导风向为偏东风,其余月份为偏西风。

Abstract:

 Based on CFL - 03 wind profile radar data from April 1 to November 30 of 2010 at Tazhong station,the temporal and spatial distribution features of wind field at the level of 850 hPa,700 hPa and 500 hPa characteristic layers at the hinterland of Taklimakan Desert were analyzed in this paper. Results show that the dominate wind direction at the level of 850 hPa is east and annual variation of wind speed is small,and wind speed is maximum in June and minimum in September at the level of 700 hPa,and the dominate wind direction in June,August and September is east ,but west in other months. The wind speed is minimum in September and maximum in November at the level of 500 hPa,and the dominate wind direction is east in June and September but west in other months.

Key words: Taklimakan desert, Tazhong, characteristic layer, wind profile radar, wind direction, wind speed
