摘　　要：基于天津市254个地面观测站数据,通过计算多种统计指标评估了高分辨率多源气象数据融合产品对2020年9月份2 m气温和10 m风速的同化结果。结果表明,就天津市全域来看,产品对2 m气温和10 m风速的同化结果与观测具有较高的一致性,但也存在区域差异,误差较大的区域主要集中在北部蓟州山区和城区。这说明在实际预报业务与应用中,对融合产品的使用要结合各个地区的特点,如地形、下垫面等因素以及变量的选择。Based on the data of 254 ground observation stations in Tianjin,the assimilation results of 2 m air temperature and 10 m wind speed by high-resolution multi-source meteorological data fusion products in September 2020 are evaluated by calculating a variety of statistical indicators.The results show that the assimilation results of 2 m air temperature and 10 m wind speed are consistent with the observations,but there are also regional differences with larger errors mainly existing in the northern Jinzhou Mountain and urban areas.Therefore,the use of fusion products should be combined with the characteristics of each region,such as terrain,underlying surface and other factors,as well as the selection of variables in the practical forecast operations.
