El Nino and La Nina ping-pong
Permalink
Enjoyed this update, thanks ENSO team!
Looking at the ENSO record, the shift back to La Nina after El Nino is typical like clockwork.
However, looking at the record (back to 1950 anyway...) it is interesting to see what looks like a, hmmm... "whipsaw anomaly"(?) - ENSO phases going from La Nina three-peat, to the current El Nino, back to a projected La Nina! If ENSO does go to La Nina this autumn, there will have been no sustained (longer than 9 months) 'ENSO Neutral' period intervening in the past 5 years?
Maybe looking to 1950 isn't far back enough to have a real grasp of trends. But such a "whipsaw" (maybe there's a better term) certainly would stand out in the 74 year record.
