The aim of this paper is to provide the community with a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in the context of ...

A data portal for regional climatic trend analysis in a Peruvian High Andes region

Schwarb, M.; Acuña, Delia; Konzelmann, Thomas; Rohrer, M.; Salzmann, N.; Serpa Lopez, B.; Silvestre, E. (Copernicus Publications, 2011-08-16)

In the frame of a Swiss-Peruvian climate change adaptation initiative (PACC), operational and historical data series of more than 100 stations of the Peruvian Meteorological and Hydrological Service (SENAMHI) are now ...

Potential impacts of early twenty-first century changes in temperature and precipitation on rainfed annual crops in the Central Andes of Peru

Sanabria, Janeet; Calanca, Pierluigi; Alarcón Velazco, Constantino; Canchari, Glicerio (Springer, 2014-03-08)

Smallholder agriculture in the Central Andes of Peru is based to large extent on rainfed cropping systems, is exposed to climatic risks and is expected to respond sensitively to increasing temperatures and shifts in the ...

Facing unprecedented drying of the Central Andes? Precipitation variability over the period AD 1000-2100

Neukom, R.; Rohrer, M.; Calanca, P.; Salzmann, N.; Huggel, C.; Acuña, Delia; Christie, D.A.; Morales, M.S. (Institute of Physics Publishing, 2015-08)

Projected future trends in water availability are associated with large uncertainties in many regions of the globe. In mountain areas with complex topography, climate models have often limited capabilities to adequately ...

Characteristics of Precipitating Storms in Glacierized Tropical Andean Cordilleras of Peru and Bolivia

Perry, L. B.; Seimon, Anton; Andrade, Marcos; Endries, J. L.; Yuter, S. E.; Velarde, Fernando; Arias, S.; Bonshoms, Marti; Burton, E.J.; Winkelmann, I. R.; Cooper, C.M.; Mamani, G.; Rado, M.; Montoya, N.; Quispe, Nelson (Taylor & Francis, 2016-06-01)

Precipitation variability in tropical high mountains is a fundamental yet poorly understood factor influencing local climatic expression and a variety of environmental processes, including glacier behavior and water ...

A comparative analysis of TRMM-rain gauge data merging techniques at the daily time scale for distributed rainfall-runoff modeling applications

Nerini, D.; Zulkafli, Z.; Wang, L.-P.; Onof, C.; Buytaert, W.; Lavado-Casimiro, W.; Guyot, J.L. (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 ...

Climate trends and variability in Ecuador (1966–2011)

Morán-Tejeda, E.; Bazo, Juan; López-Moreno, J.I.; Aguilar, E.; Azorín-Molina, C.; Sanchez‐Lorenzo, Arturo; Martínez, Rodney; Nieto, Juan J.; Mejía, R.; Martín‐Hernández, N.; Vicente-Serrano, S.M. (John Wiley and Sons Ltd, 2016-01-15)

This study detects climate trends and variability from precipitation and temperature observations in Ecuador and assesses their links to the El Niño Southern Oscillation (ENSO) for the period 1966–2011, using the El Niño ...

Multiregional satellite precipitation products evaluation over complex terrain

Derin, Y.; Anagnostou, E.; Berne, A.; Borga, M.; Boudevillain, Brice; Buytaert, W.; Chang, Che-Hao; Delrieu, Guy; Hong, Yang; Chia Hsu, Yung; Lavado-Casimiro, W.; Manz, Bastian; Moges, Semu; Nikolopoulos, Efthymios I.; Sahlu, Dejene; Salerno, Franco; Rodríguez-Sánchez, Juan-Pablo; Vergara, Humberto J.; Yilmaz, Koray K.. (American Meteorological Society, 2016-06)

An extensive evaluation of nine global-scale high-resolution satellite-based rainfall (SBR) products is performed using a minimum of 6 years (within the period of 2000-13) of reference rainfall data derived from rain gauge ...

Low-frequency modulation and trend of the relationship between ENSO and precipitation along the northern to centre Peruvian Pacific coast

Bourrel, L.; Rau, Pedro; Dewitte, Boris; Labat, David; Lavado-Casimiro, W.; Coutaud, Aude; Vera, Andrea; Alvarado, Abigail; Ordoñez, Julio (John Wiley and Sons, 2014-05-21)

The relationship between El Niño Southern Oscillation (ENSO) and precipitation along the Peruvian Pacific coast is investigated over 1964–2011 on the basis of a variety of indices accounting for the different types of El ...

Rainfall hotspots over the southern tropical Andes: Spatial distribution, rainfall intensity, and relations with large-scale atmospheric circulation

Espinoza, J.C.; Chavez, Steven; Ronchail, Josyane; Junquas, Clémentine; Takahashi, Ken; Lavado-Casimiro, W. (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 ...
