Towards a more consistent eco-hydrological modelling through multi-objective calibration: a case study in the Andean Vilcanota River basin, Peru
(Taylor and Francis Ltd., 2020)
Most hydrological studies rely on a model calibrated using discharge alone. However, judging the model reliability based on such calibration is problematic, as it does not guarantee the correct representation of internal ...

Mechanisms of tropical precipitation biases in climate models
(Springer, 2020-10-27)
We investigate the possible causes for inter-model spread in tropical zonal-mean precipitation pattern, which is divided into hemispherically symmetric and anti-symmetric modes via empirical orthogonal function analysis. ...
Assessment of ECMWF SEAS5 seasonal forecast performance over South America
(American Meteorological Society, 2020-03-11)
Seasonal predictions have a great socioeconomic potential if they are reliable and skillful. In this study, we assess the prediction performance of SEAS5, version 5 of the seasonal prediction system of the European Centre ...

A combined view on precipitation and temperature climatology and trends in the southern Andes of Peru
(John Wiley and Sons, 2020-05-13)
In the southern Peruvian Andes, communities are highly dependent on climatic conditions due to the mainly rain-fed agriculture and the importance of glaciers and snow melt as a freshwater resource. Longer-term trends and ...

Current thermal state of permafrost in the southern Peruvian Andes and potential impact from El Niño–Southern Oscillation (ENSO)
( John Wiley and Sons , 2020-05-19)
Tropical high‐mountain permafrost has a unique thermal regime due to its exposure to strong solar radiation and to rough surface snow morphology, which reduce ground heat transfer from the surface. Latent heat transfer and ...
Dry season circulation-type classification applied to precipitation and temperature in the Peruvian Andes
(John Wiley and Sons, 2020-04-07)
We present the first systematic classification of circulation regimes that characterize the Tropical Andes during the dry season (May–August). We apply the hierarchical k-means clustering method to ERA-Interim reanalysis ...
Trends and variability of precipitation extremes in the Peruvian Altiplano (1971–2013)
(John Wiley and Sons, 2020-05-24)
Precipitation extremes have been investigated throughout the last decades in different regions of the Andes. However, little attention has been paid to the Altiplano region (Central Andes), especially to the Peruvian ...
Association Between Air Pollution in Lima and the High Incidence of COVID-19: Findings from a Post Hoc Analysis
