Influence of the Madden Julian Oscillation on precipitation and surface air temperature in South America
(Springer, 2015-04-03)
The regional influence of the Madden–Julian oscillation (MJO) on South America is described. Maps of probability of weekly-averaged rainfall exceeding the upper tercile were computed for all seasons and related statistically ...
Seasonal variability of the oxygen minimum zone off Peru in a high-resolution regional coupled model
(European Geosciences Union (EGU), 2016-08-08)
In addition to being one of the most productive upwelling systems, the oceanic region off Peru is embedded in one of the most extensive oxygen minimum zones (OMZs) of the world ocean. The dynamics of the OMZ off Peru remain ...
Influence of South America orography on summertime precipitation in Southeastern South America
(Springer, 2016)
Impacts of the main South American orographic structures (the Andes, the Brazilian Plateau and the Guiana shield) on the regional climate and associated global teleconnection are investigated through numerical experiments ...
The role of the Madden–Julian oscillation on the Amazon Basin intraseasonal rainfall variability
(Wiley, 2019-01)
The relationship between the Madden–Julian oscillation (MJO) and the seasonal cycle of the intraseasonal rainfall variability in the Amazon Basin (AB) are analysed using band-pass-filtered gauge-based gridded rainfall data ...
Teleconnections between the Peruvian central Andes and northeast Brazil during extreme rainfall events in austral summer
(American Meteorological Society, 2016-02)
Extreme precipitation events in the Peruvian Andes have significant socioeconomic impacts, yet their atmospheric dynamics are poorly understood. Here austral summer (December–March) wet and dry spells and their continental- ...
Intraseasonal modulation of spring-strong wind events associated with convection in northeastern Argentina
(John Wiley & Sons Ltd, 2019-06)
The relationship between intraseasonal variability (IS; 10–90 days) and days which registered convection-associated strong surface wind events (CSSWE) over northeastern Argentina (NEA) was studied. The climatological ...
Dual constant-flux energy cascades to both large scales and small scales
(American Institute of Physics, 2017-11)
In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional fluids and wave turbulence ...
Weather regimes in the South American sector and neighbouring oceans during winter
(Springer, 2003-04)
We classified 34 years of winter daily 500 hPa geopotential height patterns over the eastern South Pacific-South America-South Atlantic region using the K-means clustering method. We found a significant classification into ...
Anisotropy and nonuniversality in scaling laws of the large-scale energy spectrum in rotating turbulence
(American Physical Society, 2012-09)
Rapidly rotating turbulent flow is characterized by the emergence of columnar structures that are representative of quasi-two-dimensional behavior of the flow. It is known that when energy is injected into the fluid at an ...
Enso Influence over Precipitation in Argentina
(Nova Science Publishers, 2016)
Argentina is located in southeastern South America and because of its extensive territory, areas with different climate features can be found. The main climate features are related to the moisture advection from the Brazilian ...
