摘　　要：本文选取典型深盆底平原地区2013~2014年气象站辐射通量数据分析其演变特征,并结合数值模拟试验,评估了WRF模式对该地区的模拟效果。结论表明:1) 辐射四分量中,向上短波辐射通量平均值为34.42 W/m2,向下短波辐射为211.57 W/m2,而向上长波辐射为403.03 W/m2,向下短波辐射为377.51 W/m2;2) 中尺度数值模式WRF常用的三种陆面过程方案均可较好地模拟出各辐射通量的变化趋势,但对辐射各分量的极值出现了高估现象,通过对比分析,Thermal方案在该地区模拟效果较好。In this paper, the evolution characteristics of the radiation flux data analysis of meteorological stations in Chengdu from 2013 to 2014 are selected, and the simulation effect of WRF mode on the area is evaluated by combining numerical simulation experiments. The conclusion shows that: 1) the overall characteristics of each surface radiation flux are similar to the normal distribution, the average of the upward short-wave radiation flux is 34.42 W/m2, the average downward short-wave radiation flux is 211.57 W/m2, the average up-wave radiation flux is 403.03 W/m2, and the average downward short-wave radiation flux is 377.51 W/m2;2) The three land surface process schemes commonly used in the mesoscale numerical model WRF can better simulate the change trend of each radiation flux. However, the extremums of the various components of the radiation were over-estimated, and through comparative analysis, the thermal scheme simulated the effect in the region.
