Impacts of different ENSO flavors and tropical Pacific convection variability (ITCZ, SPCZ) on austral summer rainfall in South America, with a focus on Peru
(John Wiley and Sons Ltd, 2018-01)
El Niño in the eastern and central Pacific has different impacts on the rainfall of South America, and the atmospheric pathways through the South Pacific Convergence Zone (SPCZ) and Inter-Tropical Convergence Zone (ITCZ) ...

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 ...

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 ...

The role of ENSO flavours and TNA on recent droughts over Amazon forests and the Northeast Brazil region
(Royal Meteorological Society, 2019-12-27)
Amazon tropical forests and the semiarid Northeast Brazil (NEB) region have registered very severe droughts during the last two decades, with a frequency that may have exceeded natural climate variability. Severe droughts ...

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 ...

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 ...

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 ...

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 ...

Control of seasonal and inter-annual rainfall distribution on the Strontium-Neodymium isotopic compositions of suspended particulate matter and implications for tracing ENSO events in the Pacific coast (Tumbes basin, Peru)
(Institut de recherche pour le développement-IRD, 2020-01)
The geochemistry of riverine sediments exported to the oceans is important for paleo-hydro-climatic reconstruction. However, climate reconstruction requires a good understanding of the relationship between geochemistry and ...
