abstract = "The La Plata Basin and Southeastern Brazil regions are affected by
extreme precipitation that are responsible for floods or droughts
which have a large impact in sectors as agriculture and
ydrological resources besides the damages in roads and towns.
Cases of landslides in mountain areas also happen associated with
the extremes. These two regions have opposite behavior already
seen in several observational studies (Nogues-Paegle and Mo, 1997,
Cunningham and Cavalcanti, 2006). The atmospheric features
associated with convection in these regions are associated with
the Pacific South America (PSA) pattern, which is the main
tropical extratropical teleconnection in the Southern Hemisphere.
In the summer, this pattern has influence on South Atlantic
Convergence Zone (SACZ), as discussed in Cunningham and Cavalcanti
(2006), Carvalho et al (2004). The objective of this study is to
analyze the Southern Hemisphere features associated with extreme
precipitation over La Plata Basin and southeastern Brazil in a
longrange simulation with an AGCM and CGCMs to verify the ability
of the models in representing the associated teleconnections
identified in observations, in a seasonal variability scale.",
