摘要
利用Micaps高空环流、自动站和卫星云等常规资料,对2017年2月20—23日出现在西藏日喀则市南部边缘易漏报的降雪(雨)天气过程进行分析。结果表明,南支槽上高原南压、南部低海拔辐合,近地面空气湿度大,冷暖空气在南部边缘一带交汇是出现此次雨雪天气过程的关键因素。
Based on Mieaps upper air circulation, automatie station and satellite cloud data,the easy omission (rain) snow weather process in southern edge of Ahigatse City of Tibet on February 20 - 23, 2017 were analyzed. The results showed that the plateau on the southern trough south and southern lowland convergence, high near ground air humidity, intersection of warm and cool air in the southern edge were the key factor of the rain and snow weather process.
