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 ...

Strength outlooks for the El Niño-Southern Oscillation
(American Meteorological Society, 2019-02)
Three strategies for creating probabilistic forecast outlooks for El Niño-Southern Oscillation (ENSO) are compared. One is subjective and is currently used by the NOAA/Climate Prediction Center (CPC) to produce official ...

Increased variability of eastern Pacific El Niño under greenhouse warming
(Nature Publishing Group, 2018-12)
The El Niño–Southern Oscillation (ENSO) is the dominant and most consequential climate variation on Earth, and is characterized by warming of equatorial Pacific sea surface temperatures (SSTs) during the El Niño phase and ...

Editorial : Tropical Climate Variability and Change: Impacts in the Amazon
(Frontiers in Earth Science, 2019-08-26)
Vast amounts of data from satellites and ground-based systems, and improvements on modeling techniques, allows a better understanding of Earth processes and advances on climate science. The tropics play a key role on global ...
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 ...
Climatology of extreme cold events in the central Peruvian Andes during austral summer: origin, types and teleconnections
(Royal Meteorological Society, 2018-08-30)
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 ...

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 ...
