abstract = "A new version of the CPTEC/INPE AGCM is used to analyze the
Intra-Americas seas region features compared to the observations.
The climate results consist on an ensemble of four integrations
with Kuo and Grell convection schemes and large scale and
microphysics precipitation. The observations are obtained from
GPCP and ERA- Interim. The general precipitation and atmospheric
features simulated by the model, such as the subtropical Atlantic
and Pacific Highs, the jetstreams and humidity fluxes are well
represented by the model. Negative precipitation bias occurs over
southeastern North America, Amazonia and southeastern South
America, while there are positive bias over Central America and
Caribbean region, but the bias are lower than in the old version.
DJF and JJA seasons show the seasonality of Southern and Northern
Hemisphere as well as the changes in the Intra-Americas seas. The
models Southern Oscillation Index compares well with the
observation and El Nino influence on Northeastern and Southern
Brazil precipitation is well captured by the model. The model
represents the Summer anticyclonic circulation at high levels over
South America (Bolivian High) and North America (Mexican High)
associated with monsoon features. Interseasonal and interannual
precipitation variability in the intertropics are linked to
humidity flux in the Inter-Americas seas region, as the fluxes are
directed from one hemisphere to the other.",
