Assessment of climate change impacts on the hydrology of the Peruvian Amazon-Andes basin
(Wiley-Blackwell, 2011-11)
In this article, we propose an investigation of the modifications of the hydrological response of two Peruvian Amazonas-Andes basins in relationship with the modifications of the precipitation and evapotranspiration rates ...
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 ...
