利用1956—2008年和布克赛尔的大风资料,对和布克赛尔县北部地区大风的时空分布特征进行统计分析。结果表明:和布克赛尔北部地区年平均大风日数为53 d,20世纪50年代较多,60年代和70年代最多,80年代明显减少,90年代之后更少;大风日数春、夏季较多,冬季较少,4—6月处于高峰期,其中5月最多。大风频率春季占全年的36%,冬季频率最低,占全年的12%。大风分布主要受地形影响,全年盛行西风(W)和西北偏西风(WNW)。
Based on the wind speed data of Hebukesaier atmosphere monitor station, this study analyzed the spatial and temporal characteristics of gale in Northern Hebukesaier County. The results show that the annual mean gale days in Hebukesaier is 53, and more in 1950s, the most in 1960s and 1970s, going down obviously in 1980s, and much less after 1990s; the gale days are more in spring and summer, less in winter, but the peak period is from April to June, thereinto the most gale days is in May.
