The 2014/15 El Niño – Part 4 – Early Evolution – Comparison with Other Satellite-Era El Niños

In the preceding post, we looked at the evolution of the weekly sea surface temperature anomalies in two regions of the equatorial Pacific (NINO3.4 and NINO1+2), comparing the data so far in 2014 to those of the strong 1982/83 and … Continue reading
