摘　　要：2022-02-05,受南支槽前西南气流的影响,拉萨市的天气过程有利于实施人工增雪作业,此次过程共实施7次人工增雪作业,作业影响区域普降小雪,初步估算受益面积约2万km^(2),累计增加降水约1.0万t。文章利用天气形势、卫星产品、多普勒雷达等资料对此次人工增雪作业进行分析和总结。On February 5,2022,the weather process in Lhasa City was favorable for implementing artificial snow enhancement operations due to the influence of the southwest airflow in front of the southern branch trough.A total of 7 artificial snow enhancement operations were carried out during this process,and the affected area was covered with light snow.The preliminary estimate benefit area is about 20000 km^(2),and the cumulative increase in precipitation is about 10000 tons.The article analyzes and summarizes the artificial snow enhancement operation using weather conditions,satellite products,Doppler radar and other data.
