Outline
To enhance the independence and controllability of regional atmospheric environment numerical prediction and its capability to support air quality forecast and air pollution warning, a CMA-GFS driving numerical prediction system (RAEMS-CMA) was established and operationally implemented. This system was based on the NCEP-GFS driving Regional Atmospheric Environmental Modeling System for eastern China (RAEMS-NCEP). The forecast effects evaluation on the major air pollutants over the YRD region from July 4th, 2023, to July 3rd, 2024, was executed. Evaluation results showed that RAEMS-CMA had good performance in forecasting the major air pollutants, e.g. correlation coefficients were generally over 0.7 and root mean square errors were 30%~70% of corresponding observation means. The performance was consistent in different forecast lengths of 24h ~ 96h. Further analysis indicated that the performance differs from air pollutants, with better skills in forecasting PM2.5 and O3. The prediction of PM10 was underestimated, while the others were overestimated. It also showed better forecast capability over the north region than over the south. The intercomparison indicated that RAEMS-CMA had slightly superior performance to that of RAEMS-EC (which was driven by ECMWF) and accordant to RAEMS-NCEP, while their differences were usually less than 5%. These results proved the applicability of CMA-GFS in numerical air quality prediction over the YRD region. At the same time, the divergent performance in pollutants and regions suggests further efforts on technological improvements and application approaches to numerical air quality prediction.
