摘要

选取2010—2017年威宁县37个炮站收集的降雹资料,以降雹次数和灾情资料等数据为基础,通过ArcGIS软件,分析威宁县近8 a的降雹资料,得到威宁县冰雹落点概率分布图。研究发现:①威宁当地气候、农作物种植时间与冰雹成灾次数之间有一定的关系;②冰雹落点受炮站布局和地形等因素影响,以雪山镇为中心区的南北走向的一条多雹带,县内多局地单点性降雹。③通过利用威宁县降雹概率分布图,可以为防雹作业指挥和冰雹自动化观测设备规划布局提供一定的理论依据。
        Meteorological data was collected from 37 artillery stations in Weining county from 2010 to 2017 and analyzed based on the frequency of hail and disasters using ArcGIS program of spatial analysis and mathematical statistics to produce a distribution map of hail probability in Weining County. The results show that: ①there is a certain relationship among the local climate, crop planting time and the number of hail disasters in Weining county. ②the occurrence of hail is affected by factors such as the distribution of artillery stations and the terrain. A hail belt with Snow Mountain Town as its central area from north to south causes single-point hail shooting in multiple places in the county. ③the distribution map of hail probability of Weining county will provide a theoretical basis for the operation of hail suppression and the planning and layout of the hail automatic observation equipment.
