Jet Stream Changes Bringing In Much Colder Weather

January 8, 2016

By Paul Homewood 




Back on 29th December, I ran the animation of the forecast jet stream from These showed the jet stream, moving much further south from the end of December position, that had persistently brought strong winds and a mild, moist airflow up from the south west. It was this pattern that had brought so much rainfall to the north west of the country.


The forecast position as at 8th January (above) has proved remarkably accurate, compared with the current situation:




The only real difference is that the flow has not moved quite as far south as predicted. Nevertheless, the country is in a much colder, showery airflow, except for the north east of Scotland, which has borne the brunt of the rainfall.

The correlation of jet stream with the low pressure systems parked to the west of the UK is clear.




The forecast is for the kink in the jet stream to wiggle its way east, bringing much colder air down from the north next week. By next Friday, we look to be in for some very cold and windy weather!





I expect the Met Office will blame it on El Nino, and tell us they warned about it all the time. Mere mortals will probably say it is just weather!

    For those who haven’t seen this-

    Interactive map of earth showing – winds, temps, ocean currents, pollution & more.
    (This is the same data used for world weather forecasting),60.01,408
    (Works well in ‘Chrome’ & ‘Firefox’)
    Click on – ‘earth’ for parameters (e.g. for Jet Streams height =250
    Click on ‘globe’ & drag to rotate;
    Click on ‘globe’ – green spot gives – Position, Wind direction & speed, Temperature.
    Click on ‘about’ for more details.

    Temperature colour key for surface layer.
    Blue = 0 to-30°C, Red = -30 to -60°C
    Green = 0 to +10°C, yellow/green = +10 to +20°C, Brown = +20 to +60°C

    North Atlantic currents –

    Tons of fun

      saveenergy – thanks for the video – closed a few gaps for me.

    With any luck, the extra pressure will cause black outs in Europe when the wind farm fail

    There is no shortage of explanations for what is about to happen, take your pick from the Gulf Stream weakening (those evil CO2 molecules melting too much Greenland ice), the North Atlantic Oscillation, the Arctic Oscillation, solar effects, climatic chaos from the strongest El Nino evah, and an alliance between Santa Claus and the Tooth Fairy:

      You forgot George W. Bush.

    Over at Piers Corbyn, a highly qualified scientist and very successful forecaster, has an interesting take on the influence of the jet stream on our weather.

    Piers says;

    “…persistent ‘Long Jet Stream stuck’ situations are a feature of the of the new weather era (Wild-Jet-Stream / Mini-Ice-Age) the world is in, and where they locate to within a hundred miles is of crucial importance.

    It appears world weather is now developing faster into this grim new era – which depends on specific confirmed and predictable solar activity developments and lunar modulation of sun-earth connections.  Related to this, what is happening in the stratosphere is now more crucial and that changes some forecast options.

    These natural weather and climate changes are of course nothing whatsoever to do with the failed delusional CO2 hypothesis which can predict nothing because CO2 has no influence on what the sun does.”

    As I said back in December, these Netweather jet stream maps are a useful tool, and their long range forecast for the winter is still looking accurate.
