Climate change scenarios for seasonal precipitation in South America from IPCC-AR4 models

A subset of climate simulations of the 20th century from the IPCC-AR4 is analyzed to assess the ability of these models to reproduce the observed climatological seasonal precipitation in South America during the period 1970-1999. Changes of the model climatology in a climate change scenario (SRESA1b...
