【摘要】 为了分析地面雨量与雷达回波强度之间的关系,文章使用江西WebGIS雷达拼图平台的雷达回波资料和江西自动气象站实时数据服务平台的地面雨量资料,采用皮尔森相关系数和paired-samples test分析统计方法,对2013—2020年3—7月江西汛期袁河流域14次大暴雨过程的雨量与CR回波进行相关性对比分析;同时对袁河流域7个国家站的大暴雨过程进行了案例分析。分析结果为开展精细化气象服务,制定防灾减灾应急预案提供一定参考。更多还原

【Abstract】 In order to analyze the relationship between the surface rainfall and the radar echo intensity,this paper uses the radar echo data of Jiangxi WebGIS radar mosaic platform and surface rainfall data of Jiangxi automatic weather station real-time data service platform.Using Pearson correlation coefficient and paired-samples test analysis statistical method,the correlation between rainfall and CR echo of 14 heavy rainstorm processes in Yuanhe River Basin during flood season in Jiangxi province from March to July,2013 to 2020 was analyzed.At the same time,a case study is conducted on the heavy rain process at seven national stations in the Yuanhe River Basin.The analysis results provide a reference for carrying out refined meteorological services and formulating emergency plans for disaster prevention and mitigation.更多还原
