;Based on the detailed hail reconls at township sites of Honghe Prefecture from 2014 to 2022. thespatial and temporal varation characteristics of hailstorms in Honghe Prefecture and the environment featuresconducive to hail disaster formation are analyzed by the methods of ArGis technology, hail shooting densityanalysis , Pearson correlation and natural breakpoint method. On this basis, the region division of hail disaster risksin Honghe Prefecture is also conducted. The results show that: ( 1 ) From 2014 to 2022, the annual hail days inHonghe Prefecture vary from 10 to 30 days, with an average of 18.4 days per year. Both the number of hail daysand the frequency of hail events show an increasing trend over the past nine years. Hailstorm tends to occur mainlyfrom July to August and from March to May, accounting for 459 and 31% of the whole year, respectively. From14: 00 to 18: 00 is the period to see most hail events, taking up 64%6. (2) The average annual hail days across the13 counties ( cities) of the prefecture are 0.6 to 6.0 days, with three high-frequency areas located around Luxi.Mile, Shiping-Jianshui, and Mengzi-Pingbian, respectively. ( 3) Hailstorm often occur in mountainous and hilly areas at the elevation from 1 ,000 m to 2,000 m above sea level ( the frequeney being 73.4% ), in the hilly andsmall inter-mountain basins with slope <5°( the frequency being 62.3%6 ), and in the sunny slope areas ( thefrequency being 57.39 ). (4) The overall risk level of hail disaster in Honghe Prefecture is low in the southwesbut high in the northeast. There are two high-risk hail disaster areas: one located in the majority of Luxi Countyand the northem part of Mile County, and the other in the northern part of Shiping County.
