Eric Webb wrote:The current amplitude, evolution, and timing of the downwelling Kelvin Waves in the Equatorial Pacific is closely mirroring 2009 this year and another downwelling KW is passing the international dateline atm which will further suppress the thermocline and maintain the heightened OHC thru the Equinox. Ironically this is about the same time when another major downwelling wave formed in 2009 and crossed the central Pacific.

Its astonishing to me how 2009 was ignored as an analog for this season. There were lots of similarities @ the sub surface and the observed zonal wind activity. There were also similarities in the Atlantic basin, with 2009 having an MDR as cool as this years.
