Abstract

Abstract: The purpose of this study was to improve the timeliness and accuracy of hail prediction and to develop a scientific and reasonable hail prevention plan. On May 3—4, 2017, a severe convective weather process occurred in south Hunan province. The time and region of this severe convective weather process were predicted by using the European central fine grid model 24 hours before the process. By using GRAPES_CAMS model data, the evolution trend of cloud system was knew and the precipitation mechanism was judged, then the temperature and height range of cloud seeding was determined, finally the operation plan was made. The radar fact sheet was used to adjust the operation plan. The results showed that, based on the traditional hail prediction method, the cloud model was introduced to accurately determine the appropriate operation height, operation location, operation time, made the operation more scientific, more targeted. After the operation, the radar echo was weakened, no data of hail disaster was collected in the operation area, and the operation effect was good.

Key words: model prediction, the plan design, hail prevention operation, Hunan province
