                         ABSTRACT: The purpose of this work was to evaluate the accuracy of 
                         The Hadley Centre Regional Climate Model (HadRM3P) in describing 
                         the seasonal variability of the main climatological features over 
                         South America and adjacent (surrounding) oceans by using long-term 
                         simulations (30 years, 1961-1990). The analysis was performed 
                         using seasonal averages from observed and simulated precipitation, 
                         temperature, sea level pressure and wind (850 and 200 hPa). The 
                         impact of lateral boundary conditions and two different sea 
                         surface temperature (SST) conditions (1983 El Niņo and 1985 La 
                         Niņa) on the simulated climate and on the accuracy in simulating 
                         both interannual and seasonal variability was studied subjectively 
                         and objectively (skill scores). Precipitation and temperature 
                         patterns in space and time as well as the main general circulation 
                         features, including details captured by the model at finer scales 
                         than those resolved by global model were simulated by the model. 
                         However, regionally, there are still systematic errors which might 
                         be related to the physics of the model (convective schemes, 
                         topography and land surface processes) and the lateral boundary 
                         conditions inherited from the global model.",
