摘要
在全球气候变暖趋势背景下,甘肃中部地区极端气象事件显著增多,尤其是冰雹灾害频繁发生,给农业生产造成了较严重损失。根据近30 a冰雹落区、地形地貌对冰雹天气发生发展的影响、冰雹移动路径分析表明,中部地区雹云生成发展和移动路径除受天气系统影响外,复杂的地形地貌是影响降雹的最主要影响因子之一。结合冰雹预报预警,提出人工消雹作业流程,取得了良好的消雹试验效果,为防雹减灾提供了科学依据。
Extreme weather events increased significantly in the central region of Gansu Province under the background of the global warming,especially the frequent hail disasters influenced the agriculture production.In this paper,the hail area and the influence of the topography on hail developing and moving track in recent 30 years were analyzed,which indicate that complex topography was one of the most influence factors for the hail shooting in the central region besides the weather system.Combined with the hail warning,the artificial hail-suppression operation flow was given.
