      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

      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
