The polar vortex works counterintuitively to what you might expect – the stronger it is, the less impactful it is. When the polar vortex is strong, cold air is less likely to plunge deep into ...
Often these stretched polar vortex events repeat themselves with time and in rare winters this can persist for the entire winter. This last happened in 2013-14 resulting in a very cold winter."
The polar vortex is not synonymous with a cold snap. In fact, the stratosphere is 10 to 30 miles above the earth’s surface and above the polar jet stream and other systems that create most ...
Beginning on January 2, 2014, sudden stratospheric warming (SSW) [dubious – discuss] led to the breakdown of the semi-permanent feature across the Arctic known as the polar vortex. Without an active upper-level vortex to keep frigid air bottled up across the Arctic, the cold air mass was forced southward as upper-level warming displaced the ...
The 2014 Bering Sea bomb cyclone at peak intensity on November 8, over the Bering Sea.This system triggered the cold wave across North America. On November 8, the northward movement of a bomb cyclone associated with Typhoon Nuri's remnants shifted the jet stream far to the north, creating an omega block pattern, which allowed a fragment of the polar vortex to descend from Arctic region into ...
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests), USA Today previously reported. It's a normal ...
The interface between the cold dry air mass of the pole and the warm moist air mass farther south defines the location of the polar front. The polar front is centered roughly at 60° latitude. A polar vortex strengthens in the winter and weakens in the summer because of its dependence on the temperature difference between the equator and the poles.
