用非静力区域气候模式（NHRCM）对该区域进行了5年的积分，以评价区域气候的可重复性。NHRCM以10 km的网格间隔嵌套在区域分析数据集中，NHRCM以4 km的网格间隔嵌套在区域分析数据集中。与AMeDAS观测相比，NHRCM很好地再现了月降水量、季节变化和区域特征。该模式还能较好地模拟强降水的发生频率。NHRCM的年平均温度与AMeDAS观测值相比存在+0.8oC的偏差。NHRCM也很好地再现了地表温度的年际变化，特别是在夏季。
Five-year integrations with the Non-hydrostatic Regional Climate Model (NHRCM) are conducted to evaluate the reproducibility of the regional climate. NHRCM, with a grid interval of 10 km, is nested in the Regional Analysis data set, and a 4 km grid interval NHRCM is nested in it. NHRCM reproduces the monthly precipitation, seasonal change, and regional features well when compared to AMeDAS observations. The model also simulates the frequency of heavy precipitation well. Annual mean temperature of NHRCM exhibits a +0.8oC bias compared to the AMeDAS observation. NHRCM also reproduces inter-annual variation of surface temperature well, especially in summer.
