Attribution of Amazon floods to modes of climate variability: A review
(John Wiley & Sons, 2020-08)
Anomalous conditions in the oceans and atmosphere have the potential to beused to enhance the predictability of flood events, enabling earlier warnings toreduce risk. In the Amazon basin, extreme flooding is consistently ...
Updating regionalization of precipitation in Ecuador
(Springer, 2021-01-07)
This article identifies homogeneous precipitation regions in Ecuador and their relationship to the El Niño-Southern Oscillation (ENSO), using monthly records from 215 rain stations for the 1968–2014 period. A k-means ...
Hydrological modeling of the Peruvian-Ecuadorian Amazon Basin using GPM-IMERG satellite-based precipitation dataset
(Copernicus GmbH, 2017-07)
In the last two decades, rainfall estimates provided by the Tropical Rainfall Measurement Mission (TRMM) have proven applicable in hydrological studies. The Global Precipitation Measurement (GPM) mission, which provides ...
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 ...
A comparative analysis of TRMM-rain gauge data merging techniques at the daily time scale for distributed rainfall-runoff modeling applications
(American Meteorological Society, 2015-01)
This study compares two nonparametric rainfall data merging methods-the mean bias correction and double-kernel smoothing-with two geostatistical methods-kriging with external drift and Bayesian combination-for optimizing ...
The role of ENSO flavours and TNA on recent droughts over Amazon forests and the Northeast Brazil region
(Royal Meteorological Society, 2019-12-27)
Amazon tropical forests and the semiarid Northeast Brazil (NEB) region have registered very severe droughts during the last two decades, with a frequency that may have exceeded natural climate variability. Severe droughts ...
Amazon River dissolved load: temporal dynamics and annual budget from the Andes to the ocean
(Springer Verlag, 2016-06)
The aim of the present study is to estimate the export fluxes of major dissolved species at the scale of the Amazon basin, to identify the main parameters controlling their spatial distribution and to identify the role of ...
Basin-scale analysis of rainfall and runoff in Peru (1969–2004): Pacific, Titicaca and Amazonas drainages
(Taylor and Francis Ltd., 2012-06)
According to the Peruvian agricultural ministry, the Pacific watersheds where the great cities and intense farming are located only benefit from 1% of the available freshwater in Peru. Hence a thorough knowledge of the ...
Warming and wetting signals emerging from analysis of changes in climate extreme indices over South America
(Elsevier B.V., 2013-01)
Here we show and discuss the results of an assessment of changes in both area-averaged and station-based climate extreme indices over South America (SA) for the 1950-2010 and 1969-2009 periods using high-quality daily ...
Projected increases in the annual flood pulse of the Western Amazon
(Institute of Physics Publishing, 2016-01)
The impact of a changing climate on the Amazon basin is a subject of intensive research because of its rich biodiversity and the significant role of rainforests in carbon cycling. Climate change has also a direct hydrological ...
