Artigo Dynamical downscaling of the precipitation in Northeast Brazil with a regional climate model during contrasting years(Royal Meteorological Society, 2013-12-03) Silva, Cláudio Moisés Santos e; Silva, A.; Oliveira, Priscilla Teles de; Lima, Kellen CarlaThe aim of this work is to evaluate how the Regional Climate Model (RegCM4) is able to simulate the precipitation in Northeast Brazil (NEB). Therefore, high-resolution (grid spacing of 20 km) simulations during the autumns of 1998 and 1999 were performed. The model was able to capture regional and inter-annual differences of the precipitation in NEB. The RegCM4 simulations showed improved in the prediction concerning the intensity and spatial distribution of the rainfall, relative to the Era Interim reanalysis dataset. The experiment based on Emanuel MIT parameterization tends to overestimate the observed precipitation while the Grell experiment underestimates it.
