Spatio-temporal patterns of thermal anomalies and drought over tropical forests driven by recent extreme climatic anomalies
(The Royal Society, 2018-08-23)
The recent 2015– 2016 El Niño (EN) event was considered as strong as the EN in 1997–1998. Given such magnitude, it was expected to result in extreme warming and moisture anomalies in tropical areas. Here we characterize ...

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. ...
The 2017 coastal El Niño
(American Meteorological Society, 2018-08)
The original concept of El Niño consisted of anomalously high sea surface temperature and heavy rainfall along the arid
northern coast of Peru (Carranza 1891; Carrillo 1893). The concept evolved into the El Niño–Southern ...

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 ...
