| 摘 要： | 基于NCEP/FNL再分析资料，利用中尺度天气预报模式（WRF）对2006—2015年1月1日—8月31日的天气形势进行模拟，分析探讨了模式对江西省夏季(6—8月)气温和降水的模拟能力。结果表明：WRF模式能准确模拟出江西省气温和降水的空间分布气候特征，模拟结果与中国区域高时空分辨率地面气象要素驱动数据集（CMFD）接近。其中，降水的模拟精度低于气温模拟；模拟的气温在鄱阳湖地区出现低值，与CMFD的偏差最大。WRF模式模拟的地面反照率偏大导致气温模拟结果偏低。

| Abstract: | Based on NCEP/FNL reanalysis data, the weather situation from January 1 to August 31 of 2006-2015 was simulated by using the Mesoscale Weather Forecast Model (WRF). The simulation capability of the model for temperature and precipitation in summer (June-August) of Jiangxi was discussed. The results showed that the spatial distribution climatic characteristics of temperature and precipitation in Jiangxi can be accurately simulated by high resolution WRF model, and the simulation results were similar with the high spatial and temporal resolution CMFD data set in China. The accuracy of precipitation simulation was lower than that of temperature simulation. Temperature simulation presented a low value in Poyang Lake area, with the largest deviation from CFMD. High surface albedo of WRF simulation resulted in low temperature simulation results. |
