Comment : Great article on the update on ENSO.

Question : To have a true El Nino, doesn't the Pacific Decadal Oscillation have to be in the positive and the Oscillation in Atlantic ocean in the negative ? Looks like the record warm SST of the Atlantic will cause the current weak El Nino to fizzle ?

I remember in November 1976, NOAA came out with their Fall and Winter forecast and it read like this : " A Colder and Drier Fall and Winter " for the Eastern half of the continental US. They were 100 % correct. It was a very Cold and Snowy Fall and Winter here in the Ohio Valley. Did they base this on the Pacific Decadal Oscillation that turned positive in August 1976 along with a weak El Nino ?
