摘要: 地表温度是反映陆-气之间热交换特征的地球物理变量,在农业气象和气候变化研究中起着重要作用。利用1981—2010年陆面模式CLM3.5模拟、CLM3.5-clcv模拟、ERA-Interim资料和观测地面温度资料在内蒙古的时空变异性进行了分析对比。结果表明:两套CLM3.5陆面模式资料和ERA-Interim地表温度都能较好地再现内蒙古地表温度的时空变化特征,其中CLM3.5模拟最好,与观测的相关系数最高、平均偏差和均方根误差都最小;四季均有冷偏差,冷季节偏差最小,暖季节偏差增大。

Abstract: Ground temperature is an important geophysical parameter in the heat exchange process of land-atmosphere interactions. It plays a significant role in weather and climate change research. Evaluation and comparison of ground temperature from 1981 to 2010 over Inner Mongolia by using the Land Surface Model CLM3.5 data,CLM3.5-clcv data,European Centre for Medium-Range Weather Forecasts Reanalysis data and observation data is necessary. After analysis of temporal and spatial variation of ground temperature in Inner Mongolia,the results show that CLM3.5,CLM3.5-clcv and ERA-Interim ground temperature could be used to reproduce the spatial and temporal variation well.The CLM3.5 is the best with highest correlation coefficient and lowest average deviation and RMS error. The three simulations all have cold bias,especially in warm season.
