摘　　要：利用自贡机场2018~2019年自动气象站地面风资料,对风场变化特征进行分析总结。结果表明:机场主要受偏北风、偏西南风影响,偏北风频率较高,较大风速出现在春夏季,静风及风向不定频率较高;午后至傍晚风速较大,夜间至清晨风速较小;全年平均风速较小,差异不明显。Based on the surface wind data of automatic weather station in Zigong airport from 2018 to 2019,this paper analyzes and summarizes the variation characteristics of wind field.The results show:1) the airport is mainly affected by the northerly wind and the southwest wind,the northerly wind frequency is higher;2) the larger wind speed appears in spring and in summer,the frequency of calm wind and variable wind direction is higher;3) the wind speed is larger from afternoon to evening,and smaller from night to early morning;4) the annual average wind speed is smaller,and the difference is not significant.
