Multiscale streamflow variability associated with El Niño/ Southern Oscillation
Streamflow responses to the El Niño/Southern Oscillation (ENSO) phenomenon in the tropical Pacific are detectable in many regions. During warm-tropical El Niño and cool-tropical La Niña episodes, streamflows are affected throughout the Americas and Australia, in northern Europe, and in parts of Africa and Asia. In North and South America, correlations between peakflow season streamflows and sea...
متن کاملEl Nino/Southern Oscillation
Three previously published proxy records of El Nino/Southern Oscillation (ENSO) variability were compared: a documentary record from coastal South America; an ice-core record from the Quelccaya ice cap in Peru; and a tree-ring record record from arid site conifers in the southwestern United States. The records were calibrated with long ENSO instrument records, and all the proxy records showed s...
متن کاملEl Niño - Southern Oscillation
El Niño (The Christ Child) is named for the unusual warm current of water flowing south near the coast of Peru whose onset is often felt near Christmas. This mostly regular event has a great effect on the Peruvian anchovy industry, at one time, one of the most productive fisheries in the world. When cold-water upwelling stops reducing the amount of nutrients in the surface waters off the South ...
متن کاملOn the possible cause of distinct El Niño types in the recent decades
Distinct El Niño types have been observed in the recent decades with warm anomalies in the eastern Pacific (Canonical El Niño, EL) and central Pacific (El Niño Modoki, EM). Among these, a basinwide tropical Pacific (TP) warming is seen during 2009 and recently during 2014. We carried out data analysis and numerical simulation experiments to understand the possible cause for different El Niño fl...
متن کاملLong-term variability in the El Niño/Southern Oscillation and associated teleconnections
We analyze global patterns of reconstructed surface temperature for insights into the behavior of the El Niño/Southern Oscillation (ENSO) and related climatic variability during the past three centuries. The global temperature reconstructions are based on calibrations of a large set of globally distributed proxy records, or “multiproxy” data, against the dominant patterns of surface temperature...
