WebDec 22, 2014 · Westerly wind bursts spanning thousands of kilometers and acting over days or perhaps weeks at a time set off internal waves that transport energy westward and eventually poleward along the western coast of South America, some of that energy bounces off and radiates back east. See sketch below:
WebThe Kelvin waves travel east and set up changes in the eastern Pacific that lead to El Niño by depressing the thermocline there. There are smaller Kelvin waves in 1995 and 1996. … WebBoth atmospheric and oceanic equatorial Kelvin waves play an important role in the dynamics of El Nino-Southern Oscillation, by transmitting changes in conditions in the Western Pacific to the Eastern Pacific. There have been studies that connect equatorial Kelvin waves to coastal Kelvin waves.
WebJun 18, 2012 · Over the Pacific, coherent interaction is simulated between evolving persistent planetary waves and convectively coupled waves bearing a resemblance to equatorial Kelvin waves or MJO-like behavior. We hypothesize that the two-way tropicalextratropical interaction for this mode acts to weaken the extratropical response … WebBoth atmospheric and oceanic equatorial Kelvin waves play an important role in the dynamics of El Nino-Southern Oscillation, by transmitting changes in conditions in the …
WebAug 16, 2024 · When in phase and collocated with Kelvin wave activity, MJO westerly wind stress contributes to the amplification of preexisting downwelling Kelvin waves, leading to earlier onset and greater strength of the resulting El Niño events.
WebApr 15, 2014 · The full development of an El Nino can, for example, dampen the development of hurricanes in the Atlantic Ocean basin, spike global temperatures and shift precipitation patterns. Drought-weary Californians have pinned their hopes for water to the development of a strong El Niño, which in the past has brought copious rainfall to the … rcf1400wvt1WebEl Niños and Kelvin waves are both triggered by winds -- or a lack thereof -- in the Pacific Ocean.
