ResumoTo investigate the impact of changes of the Amazonian land cover on the regional and the global climate, a numerical modeling experiment with the atmospheric general circulation model of the Centro de Previsão de Tempo e Estudos Climáticos (AGCM/CPTEC), coupled to the land-surface-vegetation model (Simplified Simple Biosphere Model SSiB), was effected. Four 3-years integrations were carried out for the following deforestation scenarios: (a) no deforestation, (b) current conditions, (c) a scenario predicted for 2033, and (d) large scale deforestation. Except for the land cover changes, the initial and prescribed boundary conditions were kept identical for all integrations. An intercomparison of the integrations shows that the decrease of the root depth after deforestation plays an important role in the radiation and the energy budgets during the dry season, since less moisture in the ground is available for evapotranspiration. For all scenarios there was an increase in the surface temperature, ranging between 1.0oC for the current scenario and 1.6oC for the large-scale deforestation. The surface component of the downward solar radiation increased due to a decrease of the cloud amount over the deforested areas. A cloud feedback mechanism, in which an increase of the albedo is balanced by an increase of the downward solar radiation, was observed only with the scenario for 2033 and with the large-scale deforestation. For all scenarios, a negative feedback mechanism was observed in the hydrological cycle, since a greater amount of moisture was carried to the deforested areas. The increase of the moisture convergence was greater than the reduction of the evapotranspiration in the current scenario, leading to an increase of the precipitation. A different situation was observed for other scenarios, in which the local increase of the moisture convergence was not sufficiently intense to generate an increase in precipitation; the local water recycling was the dominant factor in these scenarios. Therefore, a partial deforestation in Amazonia may lead to a local increase of precipitation. However, if the deforestation processes remain, this condition will not be sustainable, leading to a drier condition and, consequently, to a reduction of the precipitation.
