Paul Douglas on Winter Cold, Jet Stream, and Hot Chocolate

January 22, 2013

One of the most important realizations of the past year for climate scientists was the impact that ice free waters in the arctic are having on the jet stream – which drives the weather we’ve come to expect as “normal” here in the temperate latitudes.

Paul Douglas of Weather Nation sheds more light on the interplay between climate warming and weather impacts that we all feel.

  1. From the UK Met Office:

    Overnight minimum temperatures

    Last night temperatures fell to as low as – 12.2 °C in Cambridge. This was close to the lowest recorded temperature of this winter so far, which was -13.4 °C, recorded in Marham, Norfolk on the 16 January.

    Minimum temperatures Tuesday 22 January 2013

    Location Area Temperature (°C)
    Cambridge Cambridgeshire -12.2
    Andrewsfield Essex -11.1
    Cavendish Suffolk -10.6
    Rothamsted Hertfordshire -10.4
    Marham Norfolk -10.3

    and so on (the above just a selection of the 15 places quoted)

    • Paul Handover: This is the flip side of the coin that Paul Douglas seemed to want to highlight.
      “Paul Douglas of Weather Nation sheds more light on the interplay between climate warming and weather impacts that we all feel.” I wonder if Mr. Douglas or Peter could show that what is listed below are NOT still records, in spite of Paul jubilantly pointing out all of his records that he thinks were set in 2012, all the while explaining maybe the reason for it, the Jet Stream, which is subject to change, as he himself mentioned; therefore, just what is the point?

      What follows are world record high temperatures: World (Africa) El Azizia, Libya; Sept. 13, 1922, (136F):
      North America (U.S.), Death Valley, Calif.; July 10, 1913 (134F);
      Asia; Tirat Tsvi, Israel, June 21, 1942, (129F):
      Australia ,Cloncurry, Queensland; Jan. 16, 1889 (128F):
      Europe, Seville, Spain,Aug. 4, 1881 (122F):
      South America, Rivadavia, Argentina; Dec. 11, 1905 (120F):
      Canada,Midale and Yellow Grass, Saskatchewan, Canada; July 5, 1937 (113F):
      Oceania;Tuguegarao, Philippines, April 29, 1912 (108F):
      Persian Gulf (sea-surface): Aug. 5, 1924 (96F):
      Antarctica; Vanda Station, Scott Coast, Jan. 5, 1974 (59F):
      South Pole, Dec. 27, 1978, (7.5F).
      Highest average annual mean temperature (world): Dallol, Ethiopia (Oct. 1960 Dec. 1966), 94° F.
      Longest hot spell (world): Marble Bar, W. Australia, 100° F (or above) for 162 consecutive days, Oct. 30, 1923 to Apr. 7, 1924. Notice anything regarding the dates of these records? Anyone heard of the dust bowl & wasn’t that in the 30s

      This list of records was changed recently:
      New world high temperature record holder: Death Valley, California
      Extreme Weather
      September 13, 2012
      The World Meteorological Organization (WMO) announced today that the record holder for the hottest temperature ever recorded on the planet had been changed. A record dating back to 1922 in El Azizia, Libya was deemed invalid and thus the honor now falls on a temperature recorded in Death Valley, California in 1913. (please note that this record was set one hundred years ago)
      Please show me which of these records above have been broken so that I can update my records.

      Paul mentions snow:
      Snow, U.S.ACredit: NOAA
      Just this year,(2011) a weather rarity hit the United States.
      On Jan. 12, 2011, 49 out of 50 U.S. states had snow on the ground . Florida was the only snow-free state. [Image Gallery: World’s Snow Cover Seen from Space ]

  2. The Met Office Hadley Centre in collaboration with the Walker Institute for Climate System Research , University of Reading (

    “If low levels of Arctic sea ice were found to be affecting the track of the jet stream, for example, this could be seen as linked to the warming of our climate – BUT THIS IS CURRENTLY AN UNKNOWN.”

    “… it is very difficult to do this type of analysis … … so it MAY TAKE MANY YEARS before we could confirm how … … have been altered by greenhouse gases.”

      it is certainly conservative to say that changes in jet stream behavior linked to arctic ice melt are not yet settled science.
      But there are now at least 4 pretty compelling publications on this phenomenon, with more study on the way, and you hear more and more highly qualified experts in the area that are using this as a working hypotheses.

      • The Video says “Weaker zonal wind speeds favor slower moving Rossby waves, which leads to more persistent weather patterns” It doesn’t appear that there was a very persistent pattern in North and South Dakota in 1936 when both the record high and record low temperatures that still hold were set.

        Please take note of the information given below and then tell me about drastic shifts in the climate like you folks want to maintain.
        I would certainly hope that you are able to notice the year that these records were set.

        In Steele, North Dakota on July 6, 1936 the record HIGH Temperature for the state was 121⁰ F.
        In Parshall, N. Dakota on Feb. 15, 1936 the record LOW Temperature for the state was -60⁰F.

        As Thomas Huxley famously stated: “The great tragedy in science: the slaying of a beautiful hypothesis by an ugly fact.”

    guess it’s time for my annual debunking of
    “Ah looked out may winder, an there wuz snow, so there cain’t be no clay-mut change” crock.(I haven’t seen it yet)

    Peter; I feel I owe you an apology for seemingly causing you to slip to the intellectual level of the majority of your fellow “Alarmist” that would have you make this statement: “Ah looked out may winder, an there wuz snow, so there cain’t be no clay-mut change” because I know from past association with you that you can be much more articulate than that. Please allow me to point out briefly just what some other folks in different parts of the world have seen this year, 2013, when they “looked out may winder”.

    Maybe, Peter, you can incorporate this video into what you are putting together for the winter of 2013.

    Coldest weather in decades hits India; group says 107 dead
    By Manoj Kumar | Reuters – Thu, Jan 3, 2013 12:57 PM EST
    NEW DELHI (Reuters) – The coldest weather in northern India for at least 44 years has killed more than 100 homeless people, an aid group said on Thursday.
    Winters in northern India have become colder in recent years, said Rajendra Kumar Jenamani, a scientist at the Meteorological Department.

    India Bone-Chilling Cold Weather Surprises Northern Parts Without Heating Systems
    Added by guardian on January 3, 2013.
    As many as 114 people have died due to cold temperatures in India
    Meteorologist M Duraiswamy said that January 2 was the coldest day in the last 44 years.
    Overall, conditions are terrible throughout the region and official can do nothing but hope for temperatures to rise soon. Moreover, what has made the conditions even worse is the absence of resources like heating systems that could mitigate the cruel low temperatures.
