abstract = "The La Plata Basin (LPB) is an important region for social and
economic sectors of South America, mainly as a source of water and
for agriculture. Regional models are used to analyze changes in
precipitation over South America in order to provide more details
of the projected changes in specific regions. Results of regional
models from the CLARIS-LPB project are analyzed to assess changes
and uncertainties in future projections for the LPB compared to
the base period. Results from several models are taken into
account in order to assess uncertainties. The models agree in
projecting more precipitation in the whole basin and in an
increased frequency of extreme wet austral summers. The majority
of models agree in projections of drier conditions in the upper
LPB and an increase in the frequency of extreme dry austral
winters and springs. However, in the lower LPB the projections
indicate an increase in the frequency of extreme wet winters and
springs. In austral autumn the uncertainties are high in the upper
LPB. The uncertainties are low regarding increases in the
frequency of rainy days in the middle and lower LPB and in the
maximum number of consecutive dry days in the upper LPB. The
projected patterns of austral summer anomaly precipitation
variability obtained from empirical orthogonal function analysis
display the same dipole between southern LPB and the South
Atlantic Convergence Zone as in the base period, but increased
anomalies in the northern center. In the austral winter the only
anomaly signal simulated in the base period remains in the future
projections, but the maximum variability is displaced
