Abstract: The applicability of the intensity-scale approach for the verification of climate simulation is investigated in this paper.The monthly mean surface temperature simulated by a new generation of climate system model is taken as an example.While the traditional statistical verification cannot fully reflect the spatial information of the simulation error,the intensity-scale approach can quantitatively assess the spatial information of the simulation by calculating the mean square errors and skill scores of the spatial components with different wavelet scales and intensities.For example,in East Asia,the skill score of temperature threshold 230 K and spatial scale 1600 km is very low for simulations of both January of single year and multi-year average.This study shows that the intensity-scale approach is suitable for the verification of climatological temperature simulation,and can provide quantitative spatial information of the error.
