婺源雷暴大风雷达拼图回波分类与特征分析

Classification and feature analysis of radar mosaic echo of thunderstorm gale in Wuyuan

为了提高婺源区域雷暴大风天气的短临预报预警能力,文章利用婺源国家一般气象站数据和江西WebGIS雷达拼图等资料,采用数理统计和图像对比等分析方法,对婺源雷暴大风单站气象要素和雷达回波进行了分类与特征分析,根据实例分析了雷暴大风6类回波类型的具体特征,并对其强度进行了统计。研究结果为做好婺源雷暴大风天气的短临预报预警与气象服务工作提供了分析依据。

In order to improve the short-term and impending forecasting and early warning ability of thunderstorms and gale weather in Wuyuan region,this paper classifies and analyzes the meteorological elements and radar echoes of single thunderstorm and gale weather station in Wuyuan by using the data of Wuyuan national general weather station and Jiangxi WebGIS radar mosaic and adopting data statistics,images contrast and other analysis methods.According to the examples,the concrete characteristics of 6 echo types of thunderstorm gale are analyzed,and the intensity of these echo types is statistically analyzed.These research results provide an analytical basis for short-term and impending forecasting and early warning and meteorological service of thunderstorm and gale weather in Wuyuan.
