      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 

      Cai, Wenju; McPhaden, Michael J.; Grimm, Alice M.; Rodrigues, Regina R.; Taschetto, Andréa S; Garreaud, René D.; Dewitte, Boris; Poveda, Germán; Ham, Yoo-Geun; Santoso, A.; Ng, Benjamin; Anderson, Weston; Wang, Guojian; Geng, Tao; Jo, Hyun-Su; Marengo, José A.; Alves, Lincoln M.; Osman, Marisol; Li, Shujun; Wu, L.; Karamperidou, Christina; Takahashi, Ken; Vera, Carolina

      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 ...

    • Extreme El Niño Events 

      Dewitte, Boris; Takahashi, Ken

      (Elsevier, 2019)
      Acceso cerrado
      Every few years the tropical Pacific warms abnormally in association with a relaxation of the trade winds, a phenomenon known as the El Niño–Southern Oscillation (ENSO) that represents the strongest fluctuation of the ...

    • Hydroclimatic change disparity of Peruvian Pacific drainage catchments 

      Rau, P.; Bourrel, L.; Labat, D.; Frappart, F.; Ruelland, D.; Lavado-Casimiro, W.; Dewitte, Boris; Felipe-Obando, Oscar

      Peruvian Pacific drainage catchments only benefit from 2% of the total national available freshwater while they concentrate almost 50% of the population of the country. This situation is likely to lead a severe water ...

    • Increased variability of eastern Pacific El Niño under greenhouse warming 

      Cai, Wenju; Wang, G.; Dewitte, Boris; Wu, L.; Santoso, A.; Takahashi, Ken; Yang, Y.; Carréric, A.; McPhaden, M.J

      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 ...

    • Low-frequency modulation and trend of the relationship between ENSO and precipitation along the northern to centre Peruvian Pacific coast 

      Bourrel, L.; Rau, Pedro; Dewitte, Boris; Labat, David; Lavado-Casimiro, W.; Coutaud, Aude; Vera, Andrea; Alvarado, Abigail; Ordóñez Gálvez, Juan Julio

      The relationship between El Niño Southern Oscillation (ENSO) and precipitation along the Peruvian Pacific coast is investigated over 1964–2011 on the basis of a variety of indices accounting for the different types of El ...

    • Ocean climate observing requirements in support of climate research and climate information

      (Frontiers in Earth Science, 2019-07-31)
      Natural variability and change of the Earth’s climate have significant global societal impacts. With its large heat and carbon capacity and relatively slow dynamics, the ocean plays an integral role in climate, and provides ...

    • Rainfall along the coast of Peru during strong El Niño events

      While, climatologically, most areas of the Peruvian Pacific region do not experience precipitation, they can be affected by heavy rain and flooding during strong El Niño events with severe socio-economic impacts. Only four ...

    • Regionalization of rainfall over the Peruvian Pacific slope and coast 

      Rau, P.; Bourrel, L.; Labat, D.; Melo, P.; Dewitte, Boris; Frappart, F.; Lavado-Casimiro, W.; Felipe-Obando, Oscar
