This maybe bad news for those hoping for El Niño rains to give our dry California forest a big drink and fill our lakes and reservoirs. Stay Tuned, as Mother Nature is in charge of the results.

Watts Up With That?

This post will serve as the mid-September 2012 sea surface temperature anomaly update.

Sea surface temperature anomalies for the NINO3.4 region of the eastern equatorial Pacific are a commonly used index for the strength, frequency and duration of El Niño and La Niña events. In recent weeks, they have cooled to well below the threshold of El Niño conditions. For the evolution of an El Niño that starts from La Niña conditions, that dip is unusual during the satellite era (since November 1981). See Figure 1. Actually, it’s unusual for any El Niño event over the past 30 years.

    The next story at WUWT is just as interesting which discusses strataspheric circulation changes leading to ocean circulation changes. That article deals with the NAO but a guy name Earl Happ has some interesting thoughts on the effect of the antarctic strataspheric circulation on the southern oscillation index. I know that Bob Tisdale takes exception to some of Earls ideas but the effect of solar activity changes on the polar circulation might be significant and these in turn many have significant affect on the oceans. This could get interesting.
