  abstract = {{T}he ability of four regional climate models to reproduce the present-day {S}outh {A}merican climate is examined with emphasis on {L}a {P}lata {B}asin. {M}odels were integrated for the period 1991-2000 with initial and lateral boundary conditions from {ERA}-40 {R}eanalysis. {T}he ensemble sea level pressure, maximum and minimum temperatures and precipitation are evaluated in terms of seasonal means and extreme indices based on a percentile approach. {D}ispersion among the individual models and uncertainties when comparing the ensemble mean with different climatologies are also discussed. {T}he ensemble mean is warmer than the observations in {S}outh {E}astern {S}outh {A}merica ({SESA}), especially for minimum winter temperatures with errors increasing in magnitude towards the tails of the distributions. {T}he ensemble mean reproduces the broad spatial pattern of precipitation, but overestimates the convective precipitation in the tropics and the orographic precipitation along the {A}ndes and over the {B}razilian {H}ighlands, and underestimates the precipitation near the monsoon core region. {T}he models overestimate the number of wet days and underestimate the daily intensity of rainfall for both seasons suggesting a premature triggering of convection. {T}he skill of models to simulate the intensity of convective precipitation in summer in {SESA} and the variability associated with heavy precipitation events (the upper quartile daily precipitation) is far from satisfactory. {O}wing to the sparseness of the observing network, ensemble and observations uncertainties in seasonal means are comparable for some regions and seasons.},
