RISImpact of Atmospheric Blocking on South America in Austral Summer
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates atmospheric blocking over eastern South America in austral summer for the period of 1979?2014. The results show that blocking over this area is a consequence of propagating Rossby waves that ...
Seasonal Variability of the South Equatorial Current Bifurcation in the Atlantic Ocean: A Numerical Study
Publisher: American Meteorological Society
Abstract: In this study, a reduced-gravity, primitive equation OGCM is used to investigate the seasonal variability of the bifurcation of the South Equatorial Current (SEC) into the Brazil Current (BC) to the south and the North ...
The Impact of ENSO on the South Atlantic Subtropical Dipole Mode
Publisher: American Meteorological Society
Abstract: he impact of El Niño?Southern Oscillation (ENSO) on the South Atlantic subtropical dipole mode (SASD) is investigated using both observations and model simulations. The SASD is the dominant mode of coupled ocean?atmosphere ...
The Impacts of Inter–El Niño Variability on the Tropical Atlantic and Northeast Brazil Climate
Publisher: American Meteorological Society
Abstract: n this study, observations and numerical simulations are used to investigate how different El Niño events affect the development of SST anomalies in the Atlantic and how this relates to the Brazilian northeast (NE) ...
