Evidence for a modulation of the intraseasonal summer temperature in Eastern Patagonia by the Madden-Julian Oscillation
(American Geophysical Union, 2015-08)
We describe the relationship between the intraseasonal component of surface air temperature (SAT) variability in Eastern Patagonia and the Madden-Julian Oscillation (MJO) during austral summer based on ~50 years of daily ...
Interannual and interdecadal variability of atmospheric synoptic-scale activity in the Southern Hemisphere
(American Geophysical Union, 2003-01)
[1] A rotated empirical orthogonal function analysis was applied to anomalies of July atmospheric short time scale variability (or storm tracks) over the Southern Hemisphere (SH) using NCEP reanalyses. The study reveals ...
Subpolar High Anomaly Preconditioning Precipitation over South America
(American Meteorological Society, 2010-05)
The mechanisms associated with the intraseasonal variability of precipitation over South America during the spring season are investigated with emphasis on the influence of a quasi-stationary anomalous circulation over the ...
Summer precipitation variability over South America on long and short intraseasonal timescales
(Springer, 2013-12-20)
A dipole pattern in convection between the South Atlantic Convergence Zone and the subtropical plains of southeastern South America characterizes summer intraseasonal variability over the region. The dipole pattern presents ...
Intraseasonal Variability In South America during the Cold Season
(Springer, 2014-06)
Intraseasonal (IS) variability in South America is analyzed during the cold season using 10-90 day bandpass filtered OLR anomalies (FOLR). IS variability explains a large percentage of variance with maximum values over ...
Tropical and Extratropical Wave Disturbances Impact on the Amazon Basin Precipitation: Subseasonal to Intraseasonal TimescalesImpacto de las ondas tropicales y extratropicales en la precipitación de la cuenca del Amazonas: escalas de tiempo subestacional e intraestacional
(Universidade de São PauloBR, 2022)
Summer precipitation variability over Southeastern South America in a global warming scenario
(Springer, 2012-05)
December–January–February (DJF) rainfall variability in southeastern South America (SESA) is studied in 18 coupled general circulation models from the WCRP/CMIP3 dataset, for present climate and the SRESA1B climate change ...
A two-layer approximation to the Brazil Current-Intermediate Western Boundary Current System between 20 degrees S and 28 degrees S
(ELSEVIER SCI LTD, 2009)
It has been shown that the vertical structure of the Brazil Current (BC)-Intermediate Western Boundary Current (IWBC) System is dominated by the first baroclinic mode at 22 degrees S-23 degrees S. In this work, we employed ...
