Current projections note that socioeconomic pressures coould lead to more than half of the closed-cnopy beign degraded by 2030. Previous modeling studies have shown that removal of Amazon forest can lead to significantly warmer surface temperatures and drier conditions due to signifiant decreases in precipitation. By mass continuity, the decrease in ascent associated with with the deforested regions causes changes beyond the areas of disturbance. Deforestation can lead to disturbance in the general circulation, most notably the Hardley and Walker circulations. Changes in large-scale circulation lead to significant changes in precipitation outside of the deforested region: particularly over southern South America, sub Saharan West Africa, the congo and southwest Nort America. This study helps to exhibit that amazon deforetation cant be cosnidered a geographically isolated event and provides a realistic physical

This study goal was to explore the dynamical impacts due to Amazon deforestation by considering local and remote changes in the circulation and thermodynamic variables. Results were presented for two different simulations: control (CTRL) and sensivity (DEFOR). The deforested escenario was based in CCLG 2005 land use changes by rainforest with short grass. Under the BATS clasification, RegCM3 simulations of spatial patterns of temperature and precipitation over South America were similar to those observed, except the overestimation of maximum and minimum air temperature. The simulation indicates that vegetation degradation in the Amazon region implies an air temperature increase and precipitation decrease over the degraded area oer northern South America. Many othe observational studies have indicated precipitation increases over many areas of Southamerica. Precipitation increses about 10% in relation to climatological values in both framework: deforestation and climate
