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 ...

Relationship between monthly rainfall in NW peru and tropical sea surface temperature
(Hindawi Publishing Corporation, 2013-08)
This study assesses the relationship between global sea surface temperature (SST) and a regional index of rainfall (NWPR) in Piura-Tumbes, a coastal region in northwestern Peru, over the period 1965-2008 by means of the ...

A critical assessment of the JULES land surface model hydrology for humid tropical environments
(Hydrology and Earth System Sciences (HESS), 2013-01)
Global land surface models (LSMs) such as the Joint UK Land Environment Simulator (JULES) are originally developed to provide surface boundary conditions for climate models. They are increasingly used for hydrological ...

The Major Floods in the Amazonas River and Tributaries (Western Amazon Basin) during the 1970-2012 Period: A Focus on the 2012 Flood
(American Meteorological Society, 2013)
In this work, the authors analyze the origin of the extreme floods in the Peruvian Amazonas River during the 1970-2012 period, focusing on the recent April 2012 flooding (55400m3 s-1). Several hydrological variables, such ...

ENSO impact on hydrology in Peru
(Copernicus GmbH, 2013-04)
The El Niño and La Niña impacts on the hydrology of Peru were assessed based on discharge data (1968-2006) of 20 river catchments distributed over three drainage regions in Peru: 14 in the Pacific Coast (PC), 3 in the Lake ...

Trends in rainfall and temperature in the Peruvian Amazon-Andes basin over the last 40years (1965-2007)
(John Wiley & Sons, Inc., 2013-09)
The hydroclimatology of the Peruvian Amazon-Andes basin (PAB) which surface corresponding to 7% of the Amazon basin is still poorly documented. We propose here an extended and original analysis of the temporal evolution ...
