The Met Office explains how the loopy jet stream is causing the current spate of heatwaves and non heatwaves!

    The Met Office are doing meteorology?
    This is a truly stunning development /sarc

    Well here is the SW France, clearly marked ‘blue’ on his chart for 18 July we had a toasty 40C day. So from a sample of one, not very accurate.

      Odd! Computer say high 24 for 18th at Biarritz.

    The Met Office is even more loopy than the jetstream.

    I loved the comment towards the end of the video speaking of the forecast for August that, “well that could be all the computer models averaging out and giving us a very bland pattern”. Basically, “we haven’t got a clue”. Gives you confidence!

    If I remember my history, the NW Passage was navigable in the early 20th century. This must have been during a Polar warm period. So, if we can believe the met office, there must have been a similar shift in the jet stream as a result of the low Polar ice – leading to heat-waves over the Continent of Europe. No?

      Seems reasonable. I seem to remember 1922 being “unusually warm” in the Arctic. Various press cuttings here and elsewhere.
      Meteo France has orange alerts for half-a-dozen départements in the far south plus Corsica for heat; three or four above that yellow for thunderstorms. The rest of the country has no alerts.
      Max forecast for Bordeaux today and tomorrow is 27°. Biarritz will be something similar.

        Quite so, Mike. I’d like some CC Prophet to explain how the use of oil, gas and coal in 1922 (or earlier) was responsible for a rise in CO2 and the subsequent warming of the Arctic and the movement of the jet stream then. What’s that? The jet stream didn’t move in 1922? Oh b….r,

        I suspect Biarritz will be lower as it is on the coast and not a large city where UHI will play its part.

      5 stationary Rossby waves(RW); equatorial tropopause very high as ENSO moves rapidly into El Niño and the tropopause level falling from 580000 to 53000ft; Hadley cells descending phase moving towards the poles as the tropopause falls smoothing the RWs. NOT CO2!

    Don’t the climate ‘scientists’ claim the jetstream’s loopiness is influence by carbon dioxide…or maybe it’s surface temps. The reality is, of course, quite different. But, hey, let’s not allow truth, free thought and debate, and science get in the way of a lucrative lie.

      The latest (whacky) ‘theory’ I read was that excessive water extraction had caused the Earth to tilt slightly on its axis which has caused the JS to move.

        Science today is as bunkum as the snakeoil of yesteryear, bolstered by corrupt and gullible officialdom.

        Science today is going backwards with very little really ground breaking stuff since it has become committee science. The mavericks working alone, often funded by the philanthropists who now fund the retarded ecofascists, were the ones who made the most progress.

        “…going backwards…”

        Fundamental physical science has been going backwards for a hundred years! Anybody who was scientifically literate knew in the early 20th Century that “relativity” and “quantum mechanics” were essentially rubbish AS IDEAS. It was temporary scaffolding which would be cleared away, in good time, to reveal a brave new building anchored in solid rock.

        Is light a wave or a particle or both or neither? Depends on the observer and the experiment. What?? Since when did “observers” and “experiments” become part of the building blocks of the infinite Cosmos?

        A flash of light spreads out as a spherical wave through space, perhaps for billions of years, until the points in the wave front are inconceivably distant from each other, and the wave is the slightest ripple imaginable but definitely present in many far-flung locations. Then – somewhere – the wave front meets an electron and locally “decides” to interact with it. All of that dispersed energy is, after billions of years of being dispersed, instantly withdrawn from the farthest reaches and given to that one electron, – and the wave is no more. How?

        Progress was made in certain directions by treating it as a game of “as if.” We will treat the location of an electron AS IF it is an idea from statistics. We will explain the increased life span of an incoming cosmic ray sub-atomic particle AS IF time runs slowly for it but not for the particles it collides with. All sheer NONSENSE, of course; but it often worked ,in the sense of giving some good predictions and rules. For example, the quantum approach to chemistry is clever, especially when programmed into a computer, and works a treat.

        Why does the extreme nonsense “work” as a guide in certain experiments and applications? A hundred years ago science* had no answer and it still has none. None at all. Not a clue. Not a glimmer of a beginning to understanding it. Honest scientists like Sir Laurence Bragg who in 1925 was musing in a lecture at Oxford about the strangeness of those flashes of light I describe above said, in slightly different words, “I fervently hope we come to a proper understanding of all this quite quickly. It troubles me greatly.”

        We have not come to that understanding. We have gone backwards. Our physical science is a rudderless boat.
        I sometimes think our modern “geniuses” do not even know they are in the Navy.

        * Not much help is to expected from other intellectual disciplines!

    What you say is easily disprovable. I suspect you’re saying it just to try and denigrate the Met Office.

  8. July 19, 2023 1:05 pm

    And furthermore that chart us from the ECWMF, not the Met Office.

    A loopy jet stream is indicative of a planet in cooling mode!

    • Mike Jackson permalink

      And who is to say the planet is not currently in “cooling mode”? Two weak solar cycles would lend support to that hypothesis just as a new El Niño would (temporarily) tend to offset that cooling.
      What if by 2027 we are looking at average temperatures a degree or two below the last few years, longer and deeper winters, summer temperatures across Europe struggling to reach 30° in August? What are we going to do then?
      I agree that would be an extreme scenario but a meteorologist doing his job should be detecting the “straws in the wind” that would suggest a downturn is coming and not be blinded by the “received wisdom”. If we are caught looking the wrong way when that reversal does come (as it surely will) we will be in deep bother!
      And heat pumps and electric cars will absolutely not be the answer!

        “What are we [they!] going to do then?”

        Become real climate deniers!
