The relationship between South Atlantic SST and SACZ intensity and positioning
(SpringerHeidelberg, 2014)
This study explores the ocean–atmosphere
interaction in the formation and dynamics of the South
Atlantic Convergence Zone (SACZ), through the analysis
of the heat sources estimated through the outgoing longwave
radiation. ...
Variations of geomagnetic cutoff rigidity in the southern hemisphere close to 70°W (South-Atlantic Anomaly and Antarctic zones) in the period 1975–2010
(Elsevier Ltd, 2019)
© 2018 COSPARWe report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic ...
Can Geomagnetic Storms Affect Stratospheric O3 and NO x in the South Atlantic Anomaly Zone?
(Birkhauser Verlag Ag, 2021-01)
The low magnetic field in the South Atlantic Anomaly (SAA) zone facilitates the entrance of high-energy particles from the magnetosphere. When particles that are drifting in closed orbits around the Earth reach the SAA ...
Simulation capability of tropical and extratropical seasonal climate anomalies over South America
(Springer, 2005-07-26)
An ensemble of 20 extended integrations of the atmospheric model CSIRO Mark 2, forced with the sea surface temperature observed during the 1986–1998 period, was performed to analyze the simulation capability of seasonal ...
Dynamics of precipitation anomalies in tropical South America
(2022)
In this study, precipitation in Tropical South America in the 1931–2016 period is investigated by means of Principal Component Analysis and composite analysis of circulation fields. The associated dynamics are analyzed ...
Empirical–Statistical Downscaling of austral summer precipitation over South America, with a focus on the central Peruvian Andes and the equatorial Amazon basin
(American Meteorological Society, 2021-01-12)
Precipitation is one of the most difficult variables to estimate using large scale predictors. Over South America (SA), this task is even more challenging, given the complex topography of the Andes. Empirical Statistical ...
The impact of the subtropical South Atlantic SST on South American precipitation
(COPERNICUS PUBLICATIONS, 2008)
The Community Climate Model (CCM3) from the National Center for Atmospheric Research (NCAR) is used to investigate the effect of the South Atlantic sea surface temperature (SST) anomalies on interannual to decadal variability ...
