Summer 500-hPa geopotential height error characteristics of CGCM. (a) Spatial distribution of 30-year average error field. (b) Inter-annual change of regional height anomaly in NCCV, the red column is geopotential height of NCEP, which stands for observation, while the blue column is geopotential height of CGCM. (c) Inter-annual change of regional error in NCCV, that is CGCM minus CGCM.
