Over the last few days the Polar vortex has been well and truly split at 10 hPa or 100,000 feet (fig 1). But what does it all mean for us down here on the surface, particularly in the UK? Well here for what it’s worth is how the Met Office see the next 30 days or so panning out for the UK (fig 2).
Here’s a bit more information about what the splitting of the polar vortex and the associated SSW will mean in a Facebook video courtesy of the Met Office (fig 3).
Towards the end of the month, according to the GFS the cyclonic vortex centred over Scandinavia will fill leaving only a single vortex over Arctic Canada and a massive high at 10 hpa over the Barents sea (fig 4).
