2011-2012 Winter Forecast: Comparing Last Winter's Underwater Temps to Now
We did some research regarding 1 meter underwater temperatures in the ENSO regions, and decided to compare last winter's temperatures to this year's at current time of publishing.
We can see how cold the water was last year, when there was a strong La Nina in effect. This year, we can see how temperatures in the ENSO regions have decreased by 2 degrees Celsius in a span of 2 or 3 months. This rapid cooling is definitely an encouraging sign that a La Nina may be in the works for this winter.
