随着高寒地区水文模拟的不断深入，分布式水文模型迫切需要高分辨率的降雨数据作为驱动数据。因此，本研究的目的是评估的WRF模式的累积降水模拟在天山中段的性能。WRF模式配置了27、9和3 km的三重嵌套，使用四种微物理方案（莫里森、WSM 6、戈达德和Thompson）和七种积云对流方案（Kain-Fritsch、Betts-Miller-Janjic、Grell-Freitas、Grell-3、KF-CuP、New SAS和Grell-Dévényi），用于28个实验设置。通过对两次典型暴雨模拟的对比，分析了WRF配置对暴雨模拟的影响。结果表明：1）28个组合模拟的降雨面积差异显著; 2）28个试验设置显示，雪晶含量越高，模拟的降雨量越多。只有WSM 6具有随温度调节雪冰含量的机制，是最适合降水模拟的微物理方案; 3）从累积雨量及其大值分布来看，Grell-3的优势在于具有沉降效应扩展到相邻网格的机制，是最适合模拟积云对流的方案。总体而言，WRF模式具有较强的模拟复杂地形降雨的能力。通过对不同WRF方案的统计分析，找出了适合天山暴雨预报的微物理方案和积云对流方案。
With the continuous deepening of hydrological simulations in the alpine regions, high-resolution rainfall data is urgently needed as driving data for distributed hydrological models. Therefore, the objective of this study is to evaluate the performance of the WRF model for the accumulated rainfall simulations in the central segment of the Tianshan Mountains. The WRF model is configured with triple nesting of 27, 9, and 3 km for 28 experimental setups using four microphysics schemes (Morrison, WSM6, Goddard, and Thompson) and seven cumulus convection schemes (Kain-Fritsch, Betts-Miller-Janjic, Grell-Freitas, Grell-3, KF-CuP, New SAS, and Grell-Dévényi). The performance of these WRF configurations for two typical heavy rainfall simulations are first assessed via comparisons between simulation and observation; then, its influence on the simulations is analyzed. The results show that 1) There are significant differences in the rainfall area simulated by 28 combinations; 2) The 28 experimental setups show that higher snow crystal content is consistent with more rainfalls. Only the WSM6 possesses the mechanism to adjust snow and ice content with the temperature, serving as the most suitable microphysics scheme for rainfall simulation; 3) From the perspective of the accumulated rainfall and its large value distribution, the advantage of the Grell-3 possesses the mechanism for the settlement effect extended to adjacent grids, making it the most suitable cumulus convection scheme for the simulation. Overall, the WRF model presents a strong capacity for rainfall simulation in complex terrain. Statistical investigations on various WRF setups identify suitable microphysics and cumulus convection schemes to predict heavy rainfall in the Tianshan Mountains accurately.
