Abstract

The results from a series of 3‐ to 6‐year simulations of the climatic impacts of tropical deforestation using a version of the NCAR Community Climate Model (CCM1–Oz) indicate considerable sensitivity to the specification of the vegetation and soil that replaces the tropical forest. The simulations, which encompass landscapes from forest, through grass with some trees, grass‐only, no vegetation with forest soils, to a devastated terrain, suggest that the predicted climate change depends about equally on at least three factors: (i) the global model and its large‐scale circulation sensitivity, (ii) the length of the model simulation, and (iii) the nature of the prescribed land‐use change, particularly the relative magnitudes of the changes (forested to deforested) in albedo and vegetation roughness length.
