      Rainfall characteristics in the Mantaro basin over tropical Andes from a vertically pointed profile rain radar and in-situ field campaign 
      Information on the vertical structure of rain, especially near the surface is important for accurate quantitative precipitation estimation from weather and space-borne radars. In the present study, the rainfall characteristics, from a vertically pointed profile Radar in the Mantaro basin (Huancayo, ...

      Sensitivity study on the influence of parameterization schemes in WRF_ARW model on short- and medium-range precipitation forecasts in the Central Andes of Peru 
      A sensitivity study of the performance of the Weather Research and Forecasting regional model (WRF, version 3.7) to the use of different microphysics, cumulus, and boundary layer parameterizations for short- and medium-term precipitation forecast is conducted in the Central Andes of Peru.

      Climatology of extreme cold events in the Central Peruvian Andes during austral Summer: Origin, types and teleconnections 
      The climatological and large‐scale characteristics of the extreme cold events (ECEs) in the central Peruvian Andes (Mantaro basin (MB)) during austral summer (January–March) are examined using reanalysis, gridded and in‐situ surface minimum temperature (Tmin) data for the 1979‐2010 period. To describe ...

      Recent trends on glacier area retreat over the group of Nevados Caullaraju-Pastoruri (Cordillera Blanca, Peru) using Landsat imagery 
      The Cordillera Blanca, located in the central zone of the Andes Mountains in Peru, has shown a retreat in its glaciers. This paper presents a trend analysis of the glacier area over the groups of Nevados Caullaraju-Pastoruri from 1975 to 2010 using Landsat-5 Thematic Mapper (TM) imagery. In the case ...

      Variability and climate change in the Mantaro river basin, Central Peruvian Andes 
      The present work is part of the "Integrated Local Assessment of the Mantaro River Basin" (ILA Mantaro), whose main objective was: to systematize and to extend the knowledge about climate change in the Mantaro river basin, and to evaluate the climatic, physical and social aspects of its vulnerability, ...

      Trends in maximum and minimum temperature in the Central Andes of Peru (Mantaro River Basin) 
      The Mantaro River Basin (34550,08 Km2) is located on the eastern slope of the central Peruvian Andes, between the coordinates 10º34’30’’S- 13º35’30’’S/ 73º55’00’’W- 76º40’30”W. This is a very complex basin due to its geomorphology, with almost 85% of its territory located above 3000 masl. This basin ...

      Cambios en la estacionalidad de las lluvias en los Andes centrales peruanos y su relación con la circulación atmosférica a gran escala 
      Los cambios en las fechas de inicio, finalización y duración de la temporada de lluvias en los Andes centrales del Perú, específicamente en la cuenca del río Mantaro (CRM), afectan gravemente la gestión de los recursos hídricos y las principales actividades económicas de la región (ej. agricultura de ...

      Groundwater buffers decreasing glacier melt in an Andean watershed—but not forever 
      Accelerating mountain glacier recession in a warming climate threatens the sustainability of mountain water resources. The extent to which groundwater will provide resilience to these water resources is unknown, in part due to a lack of data and poorly understood interactions between groundwater and ...

      Diurnal cycle of raindrops size distribution in a valley of the Peruvian central andes 
      In the Central Andes of Peru, convective and stratiform rainfall occurs, frequently associated with convective storms. The raindrop size distributions (RSD), measured by a Parsivel-2 optical disdrometer, were characterized by the variation of their normalized parameters. The RSD dataset includes ...

      Influence of PBL parameterization schemes in WRF_ARW model on short - range precipitation's forecasts in the complex orography of Peruvian Central Andes 
      The study evaluated the sensitivity of the precipitation forecast in the central Andes of Peru of Weather Research and Forecasting (WRF) model to change the planetary boundary layer (PBL) schemes. In that region is located the Mantaro basin, which is one of the most important in the region. Here, the ...
