Assessment of ECMWF SEAS5 seasonal forecast performance over South America
(American Meteorological Society, 2020-03-11)
Seasonal predictions have a great socioeconomic potential if they are reliable and skillful. In this study, we assess the prediction performance of SEAS5, version 5 of the seasonal prediction system of the European Centre ...

A combined view on precipitation and temperature climatology and trends in the southern Andes of Peru
(John Wiley and Sons, 2020-05-13)
In the southern Peruvian Andes, communities are highly dependent on climatic conditions due to the mainly rain-fed agriculture and the importance of glaciers and snow melt as a freshwater resource. Longer-term trends and ...

Current thermal state of permafrost in the southern Peruvian Andes and potential impact from El Niño–Southern Oscillation (ENSO)
( John Wiley and Sons , 2020-05-19)
Tropical high‐mountain permafrost has a unique thermal regime due to its exposure to strong solar radiation and to rough surface snow morphology, which reduce ground heat transfer from the surface. Latent heat transfer and ...
Dry season circulation-type classification applied to precipitation and temperature in the Peruvian Andes
(John Wiley and Sons, 2020-04-07)
We present the first systematic classification of circulation regimes that characterize the Tropical Andes during the dry season (May–August). We apply the hierarchical k-means clustering method to ERA-Interim reanalysis ...
Trends and variability of precipitation extremes in the Peruvian Altiplano (1971–2013)
(John Wiley and Sons, 2020-05-24)
Precipitation extremes have been investigated throughout the last decades in different regions of the Andes. However, little attention has been paid to the Altiplano region (Central Andes), especially to the Peruvian ...
Suspended sediment dynamics in the Amazon River of Peru
(Elsevier, 2013-07)
The erosion and transport of sediments allow us to understand many activities of significance, such as crust evolution, climate change, uplift rates, continental processes, the biogeochemical cycling of pollutants and ...

Two Contrasting Severe Seasonal Extremes in Tropical South America in 2012: Flood in Amazonia and Drought in Northeast Brazil
(American Meteorological Society, 2013-11)
Two simultaneous extreme events affected tropical South America to the east of the Andes during the austral summer and fall of 2012: a severe drought in Northeast Brazil and intense rainfall and floods in Amazonia, both ...

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 ...

Climatic control on eastern Andean denudation rates (Central Cordillera from Ecuador to Bolivia)
(Elsevier, 2013-07)
The suspended sediment yield and associated current denudation rates of eight large catchments located along the eastern range of the central Andes have been determined. The catchments have been chosen as mountainous and ...

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 ...
