Keep in mind too, the better part of the last decade has been some wild transitions between ENSO events and this includes multiple super strong EL Nino's. When you account for lags which typically exist between the oceanic-atmospheric coupling and then throw in some rapid ENSO transitions and you're dealing with extreme chaos. Lots of gradients, both temperature and pressure, and combined with external forcings, what is the response of the atmosphere going to be with these gradients...very fast flows during the NH winter.
We get ourselves into some more dormant ENSO years and we will see things relax.
