RESEARCH ON THE CHARACTERISTICS AND PATHS OF HAIL DISASTER IN KUNMING CITY
Based on the hail disasters in the past 10 years,MICAPS weather situation data and the new genera-tion of Doppler weather radar data,the characteristics,paths and corresponding weather situations of flue-cured tobacco hail disasters in Kunming were analyzed.The results showed that the spatial distribution of hail disasters in Kunming was more in the north than in the south,more in the mountainous area than in the flat land.June to Au-gust was the peak period of hail disasters,late July and early August were the high-occurrence periods of hail disasters,and 15:00-17:00 was the high-occurrence time of hail disasters.Statistics showed that Kunming mainly had three hail disaster moving paths:eastward,southwest and northwest.The circulation forms affecting the moving paths were mainly two high convergence type,low trough type,south branch trough type,tropical low pressure type and subtropical high east retreat type.According to the distribution of flue-cured tobacco and other crops and the hail disaster moving paths in the city,the configuration of artificial hail control operation points could be reasonably optimized to effectively enhance the defense ability against hail disasters.
