Extreme oceanographic forcing and coastal response due to the 2015–2016 El Niño
The El Niño-Southern Oscillation is the dominant mode of interannual climate variability across the Pacific Ocean basin, with influence on the global climate. The two end members of the cycle, El Niño and La Niña, force anomalous oceanographic conditions and coastal response along the Pacific margin, exposing many heavily populated regions to increased coastal flooding and erosion hazards. Howe...
متن کاملEl Niño / Southern Oscillation and North American Land Birds by Steven
606 Introduction From the end of 1982 through the first few months of 1983, in the Galápagos Islands of the eastern tropical Pacific Ocean, there was a huge mortality of nesting seabirds. For example, populations of the Galápagos Penguin (Spheniscus mendiculus) and Flightless Cormorant (Phalacrocorax harrisi) declined by 49% and 77%, respectively (Valle and Coulter 1987). Other species, such as...
متن کاملEl Niño events recorded by stalagmite carbon isotopes.
The El Niño/Southern Oscillation (ENSO) system is a prominent component of interannual climate variability, and the Southern Oscillation Index (SOI) is a primary measure of the state of the ENSO system (1). Here, we present evidence that ENSO-related changes in the terrestrial carbon cycle can be recorded by stalagmites, thus providing a proxy for past El Niño events. Our analysis of a stalagmi...
متن کاملDynamical Mechanisms for the Teleconnection between ENSO and NAO in Late Winter
The dynamical mechanisms for the late-winter teleconnection between El NiñoSouthern Oscillation (ENSO) and the North Atlantic Oscillation (NAO) are examined using output from two global climate models and various reanalysis datasets. During El Niño winters, the intensified transient disturbances along the equatorward shifted North Pacific storm track extend their influences farther downstream, ...
متن کاملA new Approach to El Niño Prediction beyond the Spring Season.
The enormous societal importance of accurate El Niño forecasts has long been recognized. Nonetheless, our predictive capabilities were once more shown to be inadequate in 2014 when an El Nino event was widely predicted by international climate centers but failed to materialize. This result highlighted the problem of the opaque spring persistence barrier, which severely restricts longer-term, ac...
