Yes, I’m using the term Mulligan as in a replayed golf shot. Ocean-atmosphere processes have consumed most of the warm water in the eastern equatorial Pacific from the downwelling (warm) Kelvin wave that had crossed the Pacific earlier this year. But we recently discussed and illustrated how a pool of subsurface warm water had broken off that Kelvin wave, returned west, and has now fed back into the western equatorial Pacific—priming the equatorial Pacific once again. (See Part 14 – Warm Water Recirculated?) With that recent “restocking” of warm water in the western equatorial Pacific, it looks like Mother Nature might be giving El Niño a second chance to develop this year.
