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. 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. These are seasonal, and do not cause El Niño events. However, large Kelvin waves, such as those observed in early 1997, almost always lead to El Niño events. how fast are tax returns being processed 2021
