摘　　要：文章利用2010—2019年湘潭地区82个自动气象站的逐时降水资料,统计分析了湘潭地区小时降水的空间分布特征和时间变化特征,并对比了不同季节、不同区域降水的空间差异和日变化特征。研究结果为进一步研究湘潭地区精细化降水奠定了基础。Based on the hourly precipitation data from 82 automatic weather stations(AWS)in Xiangtan area during the period of 2010 to 2019,the spatial distribution and temporal variation characteristics of hourly precipitation in Xiangtan area were analyzed statistically.And the spatial difference and diurnal variation of precipitation in different seasons and regions were compared.The results lay a foundation for further study of fine-scale precipitation in Xiangtan area.
