So is the downwelling caused by the build up of the warmer water by Indonesia?  Like the clockwise circulation of the water in the in the Northern Pacific and the counter-clockwise in the Southern Pacific but with a third dimension being the downwelling?  Does the downwelling wave travel in a counter-clockwise arc south of the equator and a clockwise arc north of the equator?  Does local upwelling caused winds more readily allow for the Kelvin wave to reach the surface?  Are these waves ever blocked or prevented from rising to or warming the surface water?  Why does the Kelvin wave stay above 300 meters, a thermocline?  What are the chances of a megalodon bursting through?  (ok sorry about that last question, I just couldn't resist)
