摘　　要：对新疆博斯腾湖东南陆地风场数据进行计算,结合博斯腾湖湖陆风效应初步建立夏半年各月风场日变化模型,得出风场日变化的4个典型时段。结果表明,博斯腾湖区域测站一致性系数和风场有较好的对应关系,一致性系数<50说明风向不稳定且风速较小,一致性系数>80说明风向趋于稳定且风速较大,弱风时段主要出现在日出日落前后,且持续2 h左右的时间。该方法为博斯腾湖东南地区弱风预报提供了思路,在稳定的高压脊形势下效果尤为明显。Based on the calculation of the wind field data from the southeast land of the Bosten lake in Xinjiang,combined with the lake-land breeze effect of the Bosten lake,the daily variation model of the wind field in the summer half year was established,and four typical periods of the daily wind field change were obtained.The results show that the consistency coefficient of the Bosten lake area has a good correspondence with the wind field.If the consistency coefficient is less than 50,it indicates that the wind direction is unstable and the wind speed is small.The consistency coefficient is greater than 80,indicating that the wind direction tends to be stable and the wind speed is generally large.The weak wind period mainly occurs before and after sunrise and sunset,and has a duration of about 2 h.This method provides an idea for the forecast of weak wind periods in the southeastern part of the Bosten lake,especially in the case of stable high pressure ridges.
