湖北人工防雹作业概念模型研究

Research on Conceptual Model of Artificial Hail Prevention in Hubei Province

应用数值模式地面和高空实况资料,结合湖北2015—2017年人工防雹作业数据进行冰雹云天气系统分型,发现湖北冰雹天气发生的有利环流形势类型为西北气流型、副高边缘型、副高内部型及其他类型。通过对西北气流型、副高边缘型这2类主要冰雹云系500 hPa、700 hPa、850 hPa、地面各层影响系统、温压湿风特征进行了分析,建立了西北气流型、副高边缘型的人工防雹作业概念模型。

Using numerical model ground and high-altitude real data, combined with the data of Hubei’s artificial antihail operations from 2015 to 2017, the hail cloud weather system was classified, and the favorable circulation situation types for hail weather in Hubei were given as the northwest airflow type and the subtropical high edge type. Subtropical high internal type and other types. Based on the analysis of the two main types of hail cloud systems at 500 hPa, 700 hPa, 850 hPa, the influence system of each layer on the ground, and the characteristics of temperature and pressure humid wind, the two main types of hail cloud systems, namely the northwest airflow type and the subtropical high edge type, have been established.Conceptual model of manual anti-hail operation.
