Analysis of the Heavy Snow Weather Process in Guinan Region on March 29,2023
Using MICAPS conventional observation data,satellite cloud image data,and C-band radar data,this article analyzes the heavy snow weather process in Guinan Region,Hainan Prefecture,Qinghai Province on March 29,2023.The results show that the 500 hPa high altitude short wave trough and shear line are the main influencing systems in the high altitude of this weather process.The combination of favorable water vapor conditions,unstable stratification,and triggering mechanisms at low altitudes and on the ground constitute favorable meteorological factors for the occurrence of extreme snowfall in Guinan region.The abundant local water vapor conditions are one of the main reasons for the occurrence of this extreme snowfall weather.The small-scale cyclonic convergence system in Guinan region provides good conditions for convergence and uplift,which is another reason for the strong locality and precipitation intensity of this process.The analysis results can provide reference basis for predicting similar heavy snow weather processes in the future.
