Summer soil-precipitation coupling in South America
(Wiley Blackwell Publishing, Inc, 2011-01)
The soil moisture memory contributes to atmospheric variability and seasonal predictability and could potentially affect the development of the South American Monsoon System. The relative importance of the local land surface ...
High-elevation monsoon precipitation processes in the central Andes of Peru
(American Geophysical Union, 2020-12-27)
Measurements at the high-elevation Lamar Observatory in the Mantaro Valley (MV) in the Central Andes of Peru demonstrate a diurnal cycle of precipitation characterized by convective rainfall during the afternoon and nighttime ...
Landscape response to late Pleistocene climate change in NW Argentina: Sediment flux modulated by basin geometry and connectivity
(American Geophysical Union, 2016-02)
Fluvial fill terraces preserve sedimentary archives of landscape responses to climate change, typically over millennial timescales. In the Humahuaca Basin of NW Argentina (Eastern Cordillera, southern Central Andes), our ...
Late Quaternary megafans, fans and fluvio-aeolian interactions in the Bolivian Chaco, Tropical South America
(2012-10-15)
The Chaco is a huge plain and a main biogeographic biome of South America dominated by subtropical semi-deciduous vegetation that spreads on the Andes footslope on more than 800,000km 2 through Bolivia, Argentina and ...
Isotopic variability (δ18O, δ2 H and d-excess) during rainfall events of the north American monsoon across the Sonora River Basin, Mexico
(Elsevier Ltd, 2021)
The economic activities of the Sonora strongly depend on groundwater extraction, which is generally of recent
meteoric origin. Understanding the hydrological functioning in this semi-arid region, located in northwestern
Mexico, ...
Multivariate analysis of the energy cycle of the South American rainy season
(JOHN WILEY & SONS LTD, 2009)
The South American (SA) rainy season is studied in this paper through the application of a multivariate Empirical Orthogonal Function (EOF) analysis to a SA gridded precipitation analysis and to the components of Lorenz ...
Late Quaternary Cuiabá megafan, Brazilian Pantanal: Channel patterns and paleoenvironmental changes
(2017-05-05)
The Brazilian Pantanal wetlands comprise some of the largest Quaternary megafans in South America. The origin of these megafans has been linked to climate changes during the Late Quaternary. This study focuses on the Cuiabá ...
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 ...
Dynamics of Precipitation Anomalies in Tropical South America: A Multiscale Approach
(Universidad de Cuenca, 2023-05-08)
This PhD thesis aims to study the dynamics of precipitation anomalies and extreme precipitation
events in tropical South America (TrSA). Precipitation anomalies in TrSA are influenced by a
complex climate variability ...
