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 framework for research linking weather, climate and COVID-19
(Nature Research, 2020)
When COVID-19 began to spread, environmental scientists recognized that the world faced a dangerous upper respiratory viral disease that might exhibit sensitivity to seasonal weather conditions. Many of these scientists ...

Change in strong Eastern Pacific El Niño events dynamics in the warming climate
(Springer, 2020)
While there is evidence that ENSO activity will increase in association with the increased vertical stratification due to global warming, the underlying mechanisms remain unclear. Here we investigate this issue using the ...

Climate impacts of the El Niño–Southern Oscillation on South America
(Nature Publishing Group, 2020-04-10)
The climate of South America (SA) has long held an intimate connection with El Niño, historically describing anomalously warm sea-surface temperatures off the coastline of Peru. Indeed, throughout SA, precipitation and ...

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 ...
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 ...
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. ...
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 ...

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 ...
Twinning SENAMHI and MeteoSwiss to co-develop climate services for the agricultural sector in Peru
(Elsevier B.V., 2020-12-06)
The development and dissemination of weather and climate information is crucial to improve people's resilience and adaptability to climate variability and change. The impacts of climate variability and change are generally ...
