I know it looks like the IOD and ENSO are perfectly in sync and mutually re enforcing one another and I'm sure that they are to a degree, but what will be obvious when la nina folds like a cheap tent is that mature, stagnant ENSO events have a more difficult time initiating and coupling with the IOD than ones that develop during the early portion of the summer. This is part of why the dynamical guidance is less aggressive. Remember, ENSO at baseline is self destructive, and it will do so at least excuse imaginable....this particular event is on borrowed time as it is.
