There is no cold water in the ENSO subsurface below Nino 4 and Nino 3.4. I've done research that shows the subsurface at -200m correlates to the N. Pacific pattern. Winter's that were Strong El Nino's that had warm patterns, had subsurface cold water in Nino 4 and Nino 3.4. You can do it from another angle, El Nino's that became La Nina's the following year, had worse Winter pattern the year of the El Nino vs El Nino's that did not become La Nina's the following year. Because there is no cold water in the subsurface of the western ENSO regions, we are less likely to have a La Nina next year. This is applicable to the Winter.
