Abstract

Abstract: The surface temperature analysis field was updated to the simulation field of CESM, and the temporal and spatial distribution differences of various physical quantities of summer precipitation field and circulation field in East Asia from 1980 to 2009 were compared between the updated and non updated surface temperature simulation. The results showed that the simulation of surface temperature, precipitation, water vapor flux, zonal and meridional circulation fields of the updated model had been significantly improved, and the correlation coefficient between the updated simulation field and the reanalysis field was significantly higher than that of the unupdated model.

Key words: surface temperature, CESM model, summer precipitation, circulation field, East Asia
