Resumo | A subset of the climate simulations of the 20th century (20c3m) for the IPCC Fourth Assessment Report (AR4) are being analyzed to assess the ability of the models in reproducing the observed precipitation climatology in South America during the period 1979-1999. In addition, the changes of such climatology in a climate change scenario (SRESA1B) over the period 2070-2099 are also discussed. A total of 23 runs from 8 different models (CNRM, GFDL-CM2.0, GISS-EH, IPSL-CM4, MIROC-3.2, ECHAM5, MRI2.3.2, UKMO-HadCM3) were considered. Climatological mean seasonal precipitation from 20c3m model simulations were compared with those resulted from the Climate Prediction Center Merged Analysis of Precipitation (CMAP) dataset. For those models that an ensemble of runs are available, climatology were first computed per individual run and then averaged over all runs available for each model. Results show that models are able to reproduce the main features of the precipitation seasonal cycle over South America like the precipitation migration from central to northwestern South America during the cold season and the corresponding development over the tropical region during the warm season. Also, the seasonal evolution of the precipitation in the SACZ region is reasonably represented by the models. Although, they have deficiencies in quantifying and geographically positioning maximum precipitation values particularly those observed over the Amazon Basin, SACZ, and La Plata Basin. In addition, some models have particular problems in the Andes region, reproducing there quite larger amounts of precipitation than those observed. The low-resolution in which the Andes is represented, also affects the spatial precipitation distribution simulated by some models. Regarding the precipitation interannual variability, while some models exhibit larger variability than observed over tropical South America, the variability represented by others is quite low. Moreover, most of the models have serious deficiencies in representing the mean precipitation maximum observed over southeastern South America during winter and its associated variability. The precipitation changes projected by the SRESA1B simulations for the period 2070-2099, differ considerable among models. Nevertheless, some of them agree in showing an increment of precipitation over southeastern South America and some reduction over the Amazon Basin.. |
