NOT SO GREEN  |  RSS Confirms UAH

I’ve often wondered if residual warm waters from The Blob in the eastern extratropical Pacific have suppressed the transition to La Nina. Maybe some researcher will look into it  -  Bob Tisdale

 

Earlier this week, Dr. Roy Spencer of the University of Alabama in Huntsville ( UAH ) announced the annual lower troposphere temperature anomalies for the year 2016. See his post Global Satellites: 2016 not Statistically Warmer than 1998. Bottom line: The UAH global lower troposphere temperature anomaly for 2016 ( an strong El Niño-decay year ) was only 0.02 deg C ( that’s read 2 one-hundredths of one degree Celsius ) higher than in 1998, another strong El Niño-decay year with the previous highest value.

With much less fanfare, Remote Sensing Systems ( RSS ) released their results for December 2016 yesterday. After converting the monthly data to annual anomalies, we can see that RSS lower troposphere temperature anomalies had similar results. That is, they too showed the RSS global lower troposphere temperature anomaly for 2016 was only 0.02 deg C higher than in 1998.

Curiously, in a comparison of two comparably strong El Niño events, even though global lower troposphere temperature anomalies were much lower in 1997 than in 2015 ( the El Niño evolution years ), they were remarkably similar during the years of 1998 and 2016 ( the El Niño decay years ). In other words, the uptick from 2015 to 2016 was much less than the rise from 1997 to 1998, suggesting that the 2015/16 El Niño was weaker than the 1997/98 El Niño.

 

Thanks to Bob Tisdale.
