利用WRF中尺度模式对内蒙古地区2011年降水天气过程进行模拟分析,主要研究模式不同水平分辨率对温度和降水的影响。结果表明:水平分辨率为27km时,模式可以较好的模拟我区的降水落区和强度;不同分辨率下模拟单站降水结果存在差异,分辨率提高,模式空报率下降,但是漏报率却明显增加,TS评分降低;分辨率提高与温度预报准确率无明显的正相关,模式前12h预报准确率明显高于后12h,模式分辨率提高对后12h温度预报准确率结果有明显改善。
利用WRF中呎度模式對內矇古地區2011年降水天氣過程進行模擬分析,主要研究模式不同水平分辨率對溫度和降水的影響。結果錶明:水平分辨率為27km時,模式可以較好的模擬我區的降水落區和彊度;不同分辨率下模擬單站降水結果存在差異,分辨率提高,模式空報率下降,但是漏報率卻明顯增加,TS評分降低;分辨率提高與溫度預報準確率無明顯的正相關,模式前12h預報準確率明顯高于後12h,模式分辨率提高對後12h溫度預報準確率結果有明顯改善。

The aim of this paper is to study the effect of model horizontal resolution on temperature and precipitation by WRF in Inner Mongolia in 2011.The results showed that the model with the horizontal resolution ratio of 27kin have good performance in simulating the area and intensity of precipitation in our region. Meanwhile, the simulated precipitation of single station which result in the performance variations under different resolutions ratio, when the resolution ratio was raised, TS score and the rate of vacancy forecast decreased, but the missing report rate increased significantly. There have no obvious positive correlation between the increased resolution ratio and the forecast accuracy of temperature. The forecast accuracy of 12-hours was significantly higher than the latterl2-hours, but the latter improved more obviously by the increased resolution ratio.
