| Resumo: | The General Circulation Models of the Atmosphere (AGCM) are used for various types of studies that will depend on the scale to be evaluated. These models are able to represent the observed features of the at mospheric circulation and those models that adequately represent the average state of the atmosphere have the lowest systematic errors and have the skill to correctly simulate the interannual variations. For a model adequately simulates the seasonal cycles and the interannual variability of atmospheric variables is necessary to compare their simulations with the observed fields, whether observed data or reanalysis products. Thus, this study aims to evaluate the pattern of atmospheric circulation and precipitation using the surface model known as Integrated Biosphere Simulator (IBIS) coupled to the AGCM. For that, we used reanalysis data from the National Centers for Envirtonmental Prediction/Reanalysis 2 (NCEP/R2) and precipitation of the Global Precipitation Climatology Project (GPCP) to evaluate the model's ability to simulate the present climate (1986-2005) for the four seasons. Were calculated zonal average seasonal fields, seasonal spatial fields, and vertical section diagrams. The results showed that the MCGA was able to simulate satisfactorily the main patterns of atmospheric circulation at lower and higher levels such as the High Bolivia, the jet streams, high and low pressure centers in the Northern and Southern Hemispheres and producers precipitation systems as the South Atlantic Convergence Zone (SACZ), South Pacific Convergence Zone (SPCZ), Intertropical Convergence Zone (ITCZ) and the observed monsoon patterns. Thus, this model can be used to study both time and climate given the adequate representation of the evaluated time scales. |
