The temperature in the forecast is shown at a height of a few kilometers. The more evenly connected the blue, i.e. colder, region, the stronger it is polar cyclone, If, on the other hand, larger gaps and lighter inclusions are calculated in the direction of the north pole, the vortex is more unstable. In a polar vortex split, the blue region splits into two.
