利用WRF模式设计3种不同分辨率试验方案研究不同分辨率下湖南强降水预报效果，结果表明：两层嵌套分辨率为90、30 km时，对强降水预报效果最差；分辨率为36、12 km时，24 h模拟的大暴雨中心和实况一致，48 h模拟出了雨带的东移，但是范围较实况缩小很多；采用120、40 km分辨率时，24、48 h雨区和雨带位置一致，模拟结果基本不可信。

Using WRF model to design three different test schemes to research strong precipitation forecast effect of hunan under different resolution.The results showed that heavy rain forecast effect was the worst when two layers of nested resolution was 90,30 km,simulation of heavy rain center 24 hours a day and live was consistent when resolution was 36,12 km.,48 hours to simulate the rain belt in the east,but the actual narrowed down a lot,Using 120,40 km resolution,24,48 hours area and stretching position were consistent,the simulation results were not be trusted.
