Two numerical experiments using the Atmospheric Global Circulation Model by the Center for Weather Prediction and Climate Studies and Integrated Biosphere Simulator were performed to investigate the impacts of land use and land cover changes on the climate in the semiarid area of Northeast Brazil due to replacing natural vegetation with pasture and degraded areas. Such a disturbance led to a decrease in the mean rainfall during the dry season at the study area. A meridional dipole pattern with a near surface temperature increase (reduction) in the northern (southern) areas of the semiarid region was found. The results also highlight that land use/cover change led to changes in the surface energy components and carbon balance.
