The Wind Character of Boundary Layer During a Strong Sandstorm in Tazhong
摘要
Abstract
The wind character of Boundary layer during sandstorm in Tazhong was given by using the wind profiler radar. The main results are given as follows: April 19 2010 in Tazhong. wind dirction changed from east to west below the 1 000 m altitude before the outbreak of the sandstorm. When the sandstorm occurs the wind direction was east below the 1 500 m altitude. Wind speed near ground increased rapidly to 18.3 m/s during the forming of sandstorm. When the sandstorm occurs the wind speed decreaed to 10 m/s. In the altitude range of 300 m to 1 000 m the wind speed was lower during the sandstorm. In the altitude range of 1 000 m to 2 000 m the changes of wind speed was the same as near ground. Wind speed in above 3 000 m was as high as 20 m/s during the sandstorms. There was a significant sedimentation of sand over the area during the sandstorms, the average sinking speed was 1.2 m/s.关键词
