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

2014/15 El Niño – Part 3 – Early Evolution – Comparison with 1982/83 & 1997/98 El Niño Events

Comparisons are still being made of the 1997/98 El Niño with the El Niño forming this year. So I thought we should compare the weekly sea surface temperature anomalies for this year, in two NINO regions, with those during 1997 … Continue reading

El Niño Residuals Cause the C-Shaped Warming Pattern in the Pacific

In the recent model-data comparison of satellite-era sea surface temperature anomalies—appropriately titled Maybe the IPCC’s Modelers Should Try to Simulate Earth’s Oceans—we compared trend maps of modeled and observed sea surface temperature anomalies from 1982 to 2013. See Figure 1.  … Continue reading
