    I was musing these patterns..... SSW Canadian warming in November/December is associated with a later winter Scandinavian high. We had a very strong mid March warming which was in focused in that region. Have we been seeing the synoptics of an epic winter, play out in late Spring and early summer?

    It is NOT the media suggesting anything. They are reporting on scientific studies with a good dash of hyperbole for headline impact !!

    I don't think there is any correlation other than a propensity for more meridional patterns in low geomagnetic periods. It will depend where we are positioned in the wave pattern when it gets stuck. Not sure where we are in the solar cycle but the early upslope is usually when these conditions are most likely.

    The first image is multi-model for sea level pressure. As you can see, no detail as is to be expected; better to use heights as a very rough guide. all other parameters here:- Meteociel - Modèles de prévisions saisonnières de 1 à 6 mois de Copernicus C3S WWW.METEOCIEL.FR Meteociel propose les différents modèles de prévisions saisonnières mensuelles de ECMWF, Meteo-France, UKMO, NCEP, DWD, CMC, ECCC et JMA

    A master of camouflage in the birch tree twigs !! Buff-tip BUTTERFLY-CONSERVATION.ORG When at rest, the wings are held almost vertically against the body with two buff areas at the front of the thorax and at the tips of the forewings which look very like the pale wood of the birch.

    I have in memory a recent SSW that did not downwell at the time but it did have an effect on early Spring. Anybody remember which year that was?

    The easiest and quickest way to do that is to remove the like buttons.

    Yes, I'm amazed at the reaction to that inaccuracy. Some models with more layers may be better able to create continuity/accuracy through the levels but to claim they are two separately modelled entities is just plain wrong.

    Is there such a thing as a displacement split?

    Todays snow satellite illustrates your point well. Big beefy snow showers (red tinge) as the arctic parcel comes south.

    The only issue I'm aware of is lack of flight data on a day or two over the holidays. Flight data must have been reduced/impacted all through this strange year; has it made a difference to the accuracy statistics?

    Did someone mention insular Cannot remember ever seeing such a perfect bullseye of low heights centred on the BI Just realised that the ECM charts are clickable for meteograms. ECMWF | Charts APPS.ECMWF.INT

    Meteociel has a whole panel of charts to compare, you just need to click on voir panel multimodeles.

    Looks like it is from the DECIDER charts. Decider WWW.METOFFICE.GOV.UK Choose Decider to give fast advice to forecasting teams or traders working in weather-sensitive trades.

    If you know the years and dates, the Japanese site has 5 day means for 30, 100 and 500 heights. 5-day Mean Figures of Atmospheric Circulation DS.DATA.JMA.GO.JP Climate System Monitoring / TCC

    Brecht (sic) ... perfect timing for the Beast to put in an appearance. No science, no teleconnections no gut feeling, just the simple law of Sod. The east wind is probably the only visitor that can have unfettered access to the UK.

    Currently closely tracking 1995 and 2007 .... both years just before solar minimum was called. Who can forget December 1995 but 2007 was unremarkable. Nothing to be gleaned from that but the law of Sod dictates there will likely be some sort of beastly intervention when services are stretched owing to other pressures.

    Is there a link to go with image? Wondering if they give a reason for it.

    I don't remember seeing anything similar to the modelling of Alex. Is it because the tiny surface feature gets trapped under the cut off upper low that causes it to do a loop while remaining intact?
  24. Gael_Force
    It seems so. https://www.theparliamentmagazine.eu/news/article/towards-free-and-open-weather-data-for-all

    Big waves with this.
