From drought to flooding: understanding the abrupt 2010-11 hydrological annual cycle in the Amazonas River and tributaries
(Institute of Physics Publishing, 2012-01)
In this work we document and analyze the hydrological annual cycles characterized by a rapid transition between low and high flows in the Amazonas River (Peruvian Amazon) and we show how these events, which may impact ...

The central South America region includes Brazil, Peru, Paraguay, and Bolivia
(American Meteorological Society, 2023)
The 2022 mean temperature for central South America was 0.23°C above the 1991–2020 average (Fig. 7.13). Much of the region had near- to above-average mean annual temperatures (Fig. 7.11). Seasonally, during December–February, ...

Central South America
(American Meteorological Society, 2020-08)
Heavy rainfall events were observed in January along the dry southern coast of Peru, resulting in some locations breaking precipitation records of more than 30 years. Heavy rainfall during February led to 42 landslides ...

Revisiting wintertime cold air intrusions at the east of the Andes: propagating features from subtropical Argentina to Peruvian Amazon and relationship with large-scale circulation patterns
(Springer, 2012-12-29)
This study investigates the spatial and temporal characteristics of cold surges that propagates northward along the eastern flank of the Andes from subtropical to tropical South America analysing wintertime in situ daily ...
Rainfall hotspots over the southern tropical Andes: Spatial distribution, rainfall intensity, and relations with large-scale atmospheric circulation
(American Geophysical Union, 2015-05-11)
The Andes/Amazon transition is among the rainiest regions of the world and the interactionsbetween large-scale circulation and the topography that determine its complex rainfall distribution remainpoorly known. This work ...

Observed and projected hydroclimate changes in the Andes
(Frontiers, 2020-03-17)
The Andes is the most biodiverse region across the globe. In addition, some of the largest urban areas in South America are located within this region. Therefore, ecosystems and human population are affected by hydroclimate ...

Impacts of El Niño and La Niña in the precipitation over Perú (1965-2007)
(Sociedade Brasileira de Meteorologia, 2014-06)
The impacts of El Niño (EN) and La Niña (LN) in rainfall in Peru are evaluated using monthly data (1965-2007) of 155 stations distributed over the three hydrographic drainages of Peru: 85 in the Pacific (VP), 21 in the ...

Control of seasonal and inter-annual rainfall distribution on the Strontium-Neodymium isotopic compositions of suspended particulate matter and implications for tracing ENSO events in the Pacific coast (Tumbes basin, Peru)
(Institut de recherche pour le développement-IRD, 2020-01)
The geochemistry of riverine sediments exported to the oceans is important for paleo-hydro-climatic reconstruction. However, climate reconstruction requires a good understanding of the relationship between geochemistry and ...

Climatology of extreme cold events in the central Peruvian Andes during austral summer: origin, types and teleconnections
(Royal Meteorological Society, 2018-08-30)
The climatological and large‐scale characteristics of the extreme cold events (ECEs) in the central Peruvian Andes (Mantaro basin (MB)) during austral summer (January–March) are examined using reanalysis, gridded and in ...
Impacts of satellite-based precipitation datasets on rainfall-runoff modeling of the Western Amazon basin of Peru and Ecuador
(Elsevier, 2015-09)
Satellites are an alternative source of rainfall data used as input to hydrological models in poorly gauged or ungauged regions. They are also useful in regions with highly heterogeneous precipitation, such as the tropical ...
