浙江多源融合实况分析产品质量评估及应用

Analysis of Real Time Product Quality Evaluation and Application in Zhejiang

浙江省气象资料业务系统(MDOS)于2019年10月起接入国家气象信息中心研制的5 km多源融合实况分析产品,利用浙江省范围地面考核自动站,对气温、风、相对湿度、能见度、二源降水、三源降水等6大类观测要素的月平均相关系数、月平均绝对误差、月平均均方根误差进行逐月评估。评估结果良好,投入本地化应用。CMPAS三源融合降水数据能够精确的反映雨量的实况,应用于浙江2020年梅汛期降水监测、"黑格比"台风降水监测以及行政区面雨量计算。

The Zhejiang Meteorological Data Service System(MDOS)has been connected to the 5 km analysis of real time product developed by the National Meteorological Information Center in October 2019.It uses automatic ground assessment stations in Zhejiang to monitor temperature,wind,relative humidity by the monthly average correlation coefficients,monthly average absolute errors,and monthly average root mean square errors of six major categories of observation elements,including two-source precipitation and three-source precipitation,are evaluated monthly.The evaluation result is good and localized application has been carried out.The CMPAS three-source fusion precipitation data can accurately reflect the actual rainfall situation,and it is used for the precipitation monitoring during the plum flood season in Zhejiang in 2020,the precipitation monitoring of the“Hagupit”typhoon,and the area rainfall calculation of the administrative area.
