雅砻江流域 WRF 模式构建及应用
Building and Application of WRF Model in Yalong River Basin

针对雅砻江流域构建了数值天气预报(WRF)模式，使用 7 种云微物理参数化方案和 3 种积云对流参数化方 案对 3 场典型暴雨进行了模拟和 ETS 综合评价，得出了 WSM3 和 GD 的参数化方案组合较优的结论，为 WRF 模式 在雅砻江流域的深入应用提供了重要参考．此外，为了验证构建的 WRF 模式在水文应用方面的有效性，将其与 HEC-HMS 分布式水文模型进行了单向耦合，结果显示耦合模型对径流的模拟效果较好，说明 WRF 模式能够反映 产生洪峰和维持径流的降水信号，其在流域径流模拟和预报中有较大的应用潜力．
This paper built the weather research and forecasting(WRF)model in view of Yalong river basin，and simulated three heavy precipitation events with seven commonly used cloud microphysics schemes and three cumulus parameterization schemes to get the ETS scores．The WSM3 and GD parameterization scheme combination was proved better than the others，which provided an important reference to further application of WRF model in Yalong river basin．In addition，in order to verify the effectiveness of the hydrological applications of WRF model built in this paper，WRF model and distributed hydrological model HEC-HMS were coupled in the off-line mode．The simulation results of the coupling model was good，indicating that WRF model can reflect the signal that creates the flood peak and maintains the runoff，and it has great potential in runoff simulation and forecasting
