abstract = "This paper assesses how well the CPTEC/INPE Brazilian Global
AtmosphericModel (BAM-1.2) and the atmospheric component of the UK
Met Office HadleyCentre Global Environment Model (HadGEM3-GC3.1)
represent the main SouthAmerican monsoon features. Climatological
(19812010) ensemble means ofAtmospheric Model Intercomparison
Project (AMIP)-type climate simulationsare evaluated. The
assessment evaluated the models ability to represent theSouth
America austral summer and winter precipitation contrast and
associ-ated circulation, key South American monsoon system
elements, the associa-tion between south-east Brazil and South
America precipitation, and climato-logical (1997/1998 to
2013/2014) distributions of rainy season onset and demisedates
over south-east Brazil (15\◦S25\◦S,
40\◦W50\◦W) and the core
monsoonregion(10\◦S20\◦S,45\◦W55\◦W).Despitesomeidentifieddeficiencies,bothmod-els
depict the monsoon region and represent the main features,
including (1)the north-westsouth-east precipitation band and
associated ascending motionover central South America; (2) the
upper-level Bolivian High and the
north-eastSouthAmericatroughduringthesummer;(3)thelower-levelSouthAtlanticandPacific
subtropical anti-cyclones and (4) the low-level jet east of the
Andes. Bothmodels represent upper-level divergence and lower-level
convergence over the core monsoon region, and upper-level
convergence and lower-level divergenceover the Pacific and
Atlantic anti-cyclones associated with the regional
Walkercirculation during the pre-monsoon (spring) and peak monsoon
(summer) sea-sons. Convection over South America is weaker in
BAM-1.2 than observed, con-sistent with continental precipitation
deficit. The models reproduce the dipole-like precipitation
pattern between south-east Brazil and south-eastern SouthAmerica
during the austral summer but overestimate these patterns
spatialextent over the South Atlantic. Both models simulate the
main observed climato-logical features of rainy season onset and
demise dates for the two above definedinvestigated regions.
HadGEM3 overestimates onset dates interannual variabil-ity. These
results can contribute towards understanding climate and
land-usechange implications for environmental sustainability and
for recommending cli-mate adaptation strategies.",
