The Korean Peninsula and the United States (US) have many contrasting precipitation characteristics that are part of the oceanic monsoon and continental convection. This study evaluated 11 microphysics schemes in the Weather Research and Forecasting model in terms of vertical reflectivity structure for heavy rainfall during the summer in Korea and the US. Compared to satellite radar observation, the correlation coefficients for the reflectivity structure for 11 microphysics schemes were 0.581–0.906 and 0.745–0.918 for the Korean and US domains, respectively. We observed that a simple scheme (such as the use of single moment and limited ice categories) does not always fail, and complex methods do not always succeed. The relatively low correlation over Korea versus the US was assumed because many microphysics parameterizations were developed and tuned over the US. Consequently, some microphysics schemes exhibited a severe overestimation of reflectivity in both the upper and lower levels over the Korean Peninsula. In contrast, a microphysics scheme that was evaluated and improved for both continental and maritime convection regions, showed the best performance on the Korean Peninsula too. This highlights the importance of evaluation for various regions with different precipitation characteristics to improve parameterization of cloud microphysics. Because Korean and US domains are representative areas of oceanic monsoon and continental convection, we expect that this study can serve as a conceptual guide to suggest which microphysics parameterizations should be used for a realistic simulation in continental and oceanic monsoon precipitation regimes.

朝鲜半岛和美国 (US) 有许多不同的降水特征，它们是海洋季风和大陆对流的一部分。本研究根据韩国和美国夏季强降雨的垂直反射率结构评估了天气研究和预报模型中的 11 个微物理方案。与卫星雷达观测相比，韩国和美国领域的 11 个微物理方案的反射率结构的相关系数分别为 0.581-0.906 和 0.745-0.918。我们观察到一个简单的方案（例如使用单矩和有限的冰类别）并不总是失败，复杂的方法也不总是成功。假设韩国与美国的相关性相对较低，因为许多微物理参数化是在美国开发和调整的。因此，一些微物理方案严重高估了朝鲜半岛上层和下层的反射率。相比之下，针对大陆和海洋对流区域进行评估和改进的微物理方案在朝鲜半岛也表现出最佳性能。这凸显了对具有不同降水特征的各个区域进行评估以改进云微物理参数化的重要性。因为韩美域是海洋季风和大陆对流的代表区，
