CLM5.0对东北地区地表温度的数值模拟及评估

Numerical Simulation and Evaluation of Surface Temperature in Northeast China by CLM5.0

利用CESM (Community Earth System Model)框架最新发布的陆面模式CLM5.0模拟得到东北地区域2013年12月~2014年11月地表温度数据集;并与再分析数据集ERA5-Land进行对比分析.结果表明:CLM5.0能够揭示东北地区地表温度的时间变化特征,并与再分析数据集变化趋势保持着较好的一致性,相关系数为0.991(p=0<0.01),表明CLM5.0对东北地区的地表温度有较好的模拟性能.

The latest land surface model CLM5.0 released by the CESM(Community Earth System Model) framework was used to simulate the surface temperature data set of the northeast region from December 2013 to November 2014;and the data set ERA5-Land was compared and analyzed. The results show that: the temporal change characteristics of surface temperature in Northeast China is revenled by CLM5.0, and a good consistency with the change trend of the reanalysis data set is maintained. The correlation coefficient is 0.991(p=0<0.01), indicating that CLM5.0 has good simulation performance for the surface temperature in the Northeast.
