摘要: 本文选取2022年2月~2024年1月宿迁地区10个气象自动站的日高低温数据和EC细网格模式2 m气温预报产品,通过计算预报准确率(forecast accuracy, FA)、平均误差(mean error, ME)和均方根误差(root mean square error, RMSE)验证EC细网格模式2 m气温预报产品在宿迁地区的表现,并分析了EC不同起报时次下,模式预报结果与实况的对比情况。得到以下结论:在EC高温预报检验中,国家基本站的预报准确率比区域站预报准确率更高,吴集镇高温预报表现较差;在EC低温预报检验中,区域站的预报准确率比国家基本站预报准确率更高,泗阳低温预报表现较差。EC低温平均预报准确率高于高温平均预报准确率,对预报员参考价值更高。
Abstract: This article selects daily high and low temperature data from 10 meteorological automatic stations in Suqian area from February 2022 to January 2024, as well as EC fine grid model 2 m temperature forecast products. The performance of EC fine grid model 2 m temperature forecast products in Suqian area is verified by calculating forecast accuracy (FA), mean error (ME), and root mean square error (RMSE), and the comparison between the model forecast results and the actual situation under different EC reporting times is analyzed. The following conclusion has been drawn: in the EC high temperature forecast test, the accuracy of the national basic station forecast is higher than that of the regional station forecast, and the high temperature forecast performance in Wuji Town is poor; In the EC low temperature forecast test, the accuracy of regional stations is higher than that of national basic stations, and the performance of Siyang low temperature forecast is poor. The accuracy of EC low temperature average forecast is higher than that of high temperature average forecast, which has higher reference value for forecasters.
