Dynamics of precipitation anomalies in tropical South America
(2022)
In this study, precipitation in Tropical South America in the 1931–2016 period is investigated by means of Principal Component Analysis and composite analysis of circulation fields. The associated dynamics are analyzed ...
Orographic rainfall hot spots in the Andes‐Amazon transition according to the TRMM precipitation radar and in situ data
(American Geophysical Union (AGU), 2017-06-16)
The Andes‐Amazon transition, along the eastern Peruvian Andes, features “hot spots” with strong precipitation. Using 15 years of Tropical Rainfall Measuring Mission PR data we established a robust relation between terrain ...
Teleconnections between tropical-extratropical oceans and the daily intensity of extreme rainfall over Argentina
(Wiley, 2013-03)
A Singular value decomposition (SVD) analysis was performed jointly on the daily intensity of extreme rainfall (DIER) over Argentina and the sea surface temperature (SST) of all the oceans from 17.5 °N to 90 °S in order ...
A Model for the Relationship between Rainfall, GNSS-Derived Integrated Water Vapour, and CAPE in the Eastern Central Andes
(Multidisciplinary Digital Publishing Institute, 2021-09)
Atmospheric water vapour content is a key variable that controls the development of deep convective storms and rainfall extremes over the central Andes. Direct measurements of water vapour are challenging; however, recent ...
Rainfall in the andean páramo: New insights from high-resolution monitoring in southern Ecuador
(AMERICAN METEOROLOGICAL SOCIETY, 2018)
Impacts of different ENSO flavors and tropical Pacific convection variability (ITCZ, SPCZ) on austral summer rainfall in South America, with a focus on Peru
(John Wiley and Sons Ltd, 2018-01)
El Niño in the eastern and central Pacific has different impacts on the rainfall of South America, and the atmospheric pathways through the South Pacific Convergence Zone (SPCZ) and Inter-Tropical Convergence Zone (ITCZ) ...
Data Descriptor: Daily observations of stable isotope ratios of rainfall in the tropics
(Nature Publishing Group, 2019-10-08)
We present precipitation isotope data (delta H-2 and delta O-18 values) from 19 stations across the tropics collected from 2012 to 2017 under the Coordinated Research Project F31004 sponsored by the International Atomic ...
Spatio-temporal rainfall variability in the Amazon basin countries (Brazil, Peru, Bolivia, Colombia, and Ecuador)
(Wiley Online Library, 2009-09)
Rainfall variability in the Amazon basin (AB) is analysed for the 1964-2003 period. It is based on 756 pluviometric stations distributed throughout the AB countries. For the first time it includes data from Bolivia, Peru, ...
