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 … WebUnder normal conditions, the tropics’ prevailing easterly winds push Sun-warmed surface waters across the Pacific from the Americas toward Indonesia, creating a deep pool of …
WebThe two phenomena, Kelvin waves and El Niño, are linked by wind. Pacific trade winds blow from east to west, pushing sun-warmed surface waters toward Indonesia. As a result, the … WebApr 10, 2024 · Specifically, the SST anomalies in the Atlantic Ocean can drive easterly anomalies over the equatorial western Pacific during the decay phase of El Niño, which induce an upwelling oceanic Kelvin wave, accelerating its demise (e.g., Kim & Yu, 2024).

They also provide the oceanic “memory” that is so important to year-to-year variability and ENSO. Rossby and Kelvin waves also exist in the atmosphere, but these move much faster than their oceanic counterparts.
WebApr 3, 2015 · One of those missing factors was unusually high temperature in the upper 150 m of the ocean along the equator (in essence, an excess of “heat content”), which generally preconditions the Pacific to subsequent El Niño onset (Meinen and McPhaden, 2000; McPhaden 2012). Figure 6.
