Abstract | We investigate the impacts of an improved atmospheric absorption on radiative fluxes, atmospheric circulation and hydrological cycle for long-term GCM integrations. For these runs we use the operational version of the CPTEC AGCM and its enhanced version with a new solar radiation scheme. There is an 8% increase in the annual mean global average atmospheric absorption in the enhanced integration as compared with the operational model integration. The extra absorption is due to gases (0.5%), water vapor continuum (1.5%) and background aerosols (6%), which were not considered in the operational solar radiation scheme. In clear-sky conditions the enhanced model atmospheric absorption is in agreement with observations to within ±3 W/m2, while in all-sky conditions the remaining errors are related to unaccounted cloud absorption. There is a general warm up of the atmosphere in the enhanced model with temperatures increasing up to 3K in the troposphere and 58K in the stratosphere, bringing the model closer to reference values. The intensity of the tropospheric jets is reduced by 78%, while that of the polar night stratospheric jet are increased by 5-10%, reducing the model systematic error. The reduced availability of latent energy for the saturated convective processes weakens the meridional circulation and slows down the hydrological cycle. The model overestimation of DJF precipitation over the SPCZ and SACZ regions is reduced by 0.51.0 mmday−1 and over the northern hemisphere storm tracks region by 0.5 mmday−1. In the monthly time scale, the changes on the precipitation distribution over the SACZ region are found to be much larger ± 23mmday−1.. |
