ENSO prediction can be very tricky but at least we are beginning to understand what factors make ENSO switch to negative or positive...however, we have little idea with PDO, we can only read if it's a positive or negative currently but there seems to be no way to predict if it's going to flip or stay the same after some time.
If El Nino is on the way it'll flip during the summer. But usually either the PDO or PMM signatures are much more positive preceding any El Nino.
So have there ever been El Ninos with -PDOs? How did EPAC activity fare during such years?
