对一个非流体静力区域气候模式（NHRCM）进行了20年的整合，再现了当前的气候。NHRCM较好地模拟了日本的年平均地表温度和降水。在用观测资料对模式的年降水量进行验证时，有一个明显的异常值。要重现该观测点的降水，需要比5公里更细的网格间距。区域模式成功模拟了一般环流模式无法再现的强降水。该模型很好地再现了日本大部分地区的雪深，但日本海北部海岸的雪深被低估了。
A 20-year-integration of a non-hydrostatic regional climate model (NHRCM) was conducted to reproduce the present climate. The annual mean surface temperature and precipitation of Japan are well simulated in NHRCM. There was one conspicuous outlier in the verification of the model's annual precipitation with observations. An even finer grid spacing than 5 km would be required to reproduce the precipitation at this observation point. The regional model successfully simulated heavy precipitation that a general circulation model could not reproduce. This model reproduced snow depth well in most of Japan, except in the north on the coast of the Sea of Japan, where the depth was underestimated.
