Temperature and Precipitation Anomalies in previous El Niño events (Detailed Charts)

The most frequent classes in previous warmer/cooler SST events are shown with circles ("high," "normal" or "low" for temperature, and "wet," "normal" or "dry" for precipitation) and related statistical confidence levels (%) as indicated in the legends.
"Undecided" as indicated by a gray square means that the most frequent class could not be isolated.
Grid squares with a climatological probability of "dry" exceeding 33% are shown with a square in their background of the grid.
No marks (circles or squares) are shown for a grid squares where insufficient data were available.
