2013—2015年二连浩特市近地面层风变化浅析

Analysis on the Wind Variation of Ground Layer in Erenhot from 2013 to 2015

文章利用二连浩特市2013—2015年高空探测数据,分析近地面层月、四季风向、风速变化,结果表明:2013年和2015年主导风向随着高度的增加由西逐渐向西北方向偏转;2014年主导风向为西北,随着高度的增加风向没有改变。2013—2015年5月距离地面300m高度风速最大,4月和10月次之;从季节来看,风速变化为春季﹥秋季﹥冬季﹥夏季。

Basing on the aerological sounding data of Erenhot from 2013 to 2015, this article analyzed the wind speed and wind direction in different mouth and season. The results showed that the predominant wind direction was deflecting from west to northwest with the altitude increasing in 2013 and 2015, the predominant wind direction was northwest in 2014, the wind direction was not changed with altitude increasing. The wind speed was the largest in 300 m from ground in May from 2013 to 2015, the wind speed was second in April and October, the wind speed was first in spring, the second was in autumn, the third was in winter, the fourth was in summer.
