donsutherland1 Posted February 5, 2020 Share Posted February 5, 2020 From Copernicus: Global temperatures were substantially above average in January 2020. The month was: - 0.77°C warmer than the average January from 1981-2010, becoming by a narrow margin the warmest January in this data record; - warmer by 0.03°C than January 2016, which was previously the warmest January; - close to 0.2°C warmer than January 2017, which is now the third warmest January; - exceeded in anomalous warmth only by February and March 2016. European-average temperature anomalies are generally larger and more variable than global anomalies, especially in winter, when they can change by several degrees from one month to the next. The European-average temperature for January 2020 was particularly high. The month was: - 3.1°C warmer than the average January in the period 1981-2010; -warmer than any other January in this data record, by about 0.2ºC in the case of January 2007, the previous warmest January. https://climate.copernicus.eu/surface-air-temperature-january-2020 3 Link to comment Share on other sites More sharing options...

donsutherland1 Posted February 15, 2020 Author Share Posted February 15, 2020 On GISS, January 2020 was the warmest January on record globally. The temperature anomaly was +1.18°C, which was narrowly above the previous record of +1.17°C from 2016. Link to comment Share on other sites More sharing options...

Chinook Posted February 17, 2020 Share Posted February 17, 2020 I am not sure if you saw my recent post about the recent Iceland low pressure. There have been several strong low pressures have been in the Iceland region this winter. Seemingly, no matter what happens, Europe continues to get warmer air masses. I have heard that January 2020 was tied for the warmest January on record. (Source: Brian Brettscheider/ Climatologist49 on twitter.) I have barely seen any TropicalTidbits maps where the surface temperature was below normal in eastern Europe. 2 Link to comment Share on other sites More sharing options...

Wow. I was not expecting that. The average ONI over the last 3 and 6 months is only 0.5 and 0.3 respectively. Somewhat interesting...the UAH stratosphere temperature spiked up this month. This is only the 3rd time a spike has occurred. The other two were from El Chichon and Pinatubo. 1 Link to comment Share on other sites More sharing options...

bdgwx Posted March 4, 2020 Share Posted March 4, 2020 Hmm...Dr. Spencer is suggesting the smoke warmed both the troposphere and stratosphere. Typically aerosols cool the troposhere and warm the stratosphere. This is an unusual event in that the spike up is observed in both layers. I'm a bit skeptical of his smoke causing radiation induced warming (aka greenhouse effect) claim, but I'm open to hearing what evidence he presents. The thing is that the February troposphere anomaly is primarily the result of warming in the NH. My first thought is that the record +AO may be partly to blame with the spike. 2 Link to comment Share on other sites More sharing options...

Could it be the Taal Volcano for the stratosphere? It wasn't anything like Pintatubo but it could have some smaller effect. Link to comment Share on other sites More sharing options...

I was watching aerosol optical depths closely after that eruption and while there was a lot tephra lofted into the troposphere it didn't appear as if much sulphate aerosols made it into the stratosphere. I think the Australia wildfire smoke is a better hypothesis at this point. In regards to the troposphere...volcanoes typically cool this layer. I don't know of a case where warming resulted from an eruption. And I'm not understanding the link with smoke either. I thought smoke was more effective at blocking incoming shortwave radiation than it was at trapping outgoing longwave radiation. 1 Link to comment Share on other sites More sharing options...

Spencer is missing the two obvious factors for UAH warmth: GHG and improved satellites with no diurnal drift. Evidence for the last point is the UAH trace - the period after the 2016 nino is much warmer relative to the super nino peak than the period after the 1998 nino. What happened in 1998? the MSU to AMSU transition. Scientists still don't know which satellite was right NOAA-14 or NOAA-15. UAH picked the colder satellite, of course, which looks like the wrong choice when compared against other series. Meanwhile per the article below, recent satellites have essentially no diurnal drift, with very stable performance for climate detection. https://advances.sciencemag.org/content/4/10/eaau0049.full 3 Link to comment Share on other sites More sharing options...

ERA was only up by 0.02C. I keep wondering if UAH is contaminated by what happens in the stratosphere more so than RSS. If so that would partly explain UAH's 0.13C/decade trend which is far lower than what any other dataset shows. Link to comment Share on other sites More sharing options...

Almost a decade of cooling in UAH6 relative to RSS after the MSU to AMSU transition in 1998. Recently introduction of satellites with limited diurnal drift has reduced the trend differences between RSS+UAH (see link above). 1 Link to comment Share on other sites More sharing options...

bdgwx Posted April 8, 2020 Share Posted April 8, 2020 UAH also recorded another increase in stratospheric temperatures. If history is any guide then that means further troposphere cooling is around the corner. The leading hypothesis for stratospheric warming is still wildfire smoke.
