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风场时空分布特征,得到了4月至11月各月的高空风廓线。结果表明,塔中春秋季风场结构类似,中高层多为西风,风速较大,低层多为东风,风速较小,整层风速与高度成正比;夏季高层风速变小,低层风速增大,东风层增厚,夏季塔中地区上空100~200 m高度层存在明显风速切变带。

Abstract: Wind fields at boundary layer in hinterland of the Taklimakan Desert were investigated by the CFL-03 Wind Profile Radar. Its observation data from April 1 to November 30, 2010 were used to figure out the spatio-temporal patterns of boundary layer wind fields in hinterland of the Taklimakan Desert. The wind field structures are similar in spring and autumn: wind direction at upper layer is west and wind speed is relatively high, while wind direction at lower layer is east and wind speed is relatively low. In summer, wind speed decreases at upper layer and increases at the lower layer, so wind speed changes little from the ground to high altitude; a clear wind shear region exists in 100~200 m altitude due to impact of weather systems.

Key words: Taklimakan Desert, hinterland, boundary layer, wind direction, wind speed, wind profile radar
