Abstract Based on the daily ground snowfall observation data in Weining County from 2008 to 2019 and the L-band radar sounding observation data during the same period,this paper analyzes the temperature,dew point temperature and inversion distribution characteristics of the L-band radar before the snowfall by using mathematical statistics.And the forecast indicators are established.Then,the snowfall weather in 2020 is tested.The results show that the temperature forecast indicators have achieved good forecasting results,which can be used to guide the snowfall weather forecast in Weining.
