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 pattern continued mostly uninterrupted throughout ...
