Why is the polar vortex collapsing?
The polar vortex may be disrupted by the increase in temperature and pressure in the stratosphere, an event called ” sudden stratospheric warming “, which leads to the collapse of the polar vortex.
What likely caused the polar vortex to shift?
The stronger the winds, the more the air inside is isolated from warmer latitudes, and the colder it gets. When the Arctic polar vortex is especially strong and stable (left globe), it encourages the polar jet stream, down in the troposphere, to shift northward.
How often do polar vortexes happen?
This occurs fairly regularly during wintertime and is often associated with large outbreaks of Arctic air in the United States. The one that occurred January 2014 is similar to many other cold outbreaks that have occurred in the past, including several notable colder outbreaks in 1977, 1982, 1985 and 1989.
What caused the 2014 polar vortex event?
The event occurred in early 2014 and was caused by a southward shift of the North Polar Vortex. Record-low temperatures also extended well into March. On January 2, an Arctic cold front initially associated with a nor’easter tracked across Canada and the United States, resulting in heavy snowfall.
What was the North American cold wave of 2014?
The 2014 North American cold wave was an extreme weather event that extended through the late winter months of the 2013–2014 winter season, and was also part of an unusually cold winter affecting parts of Canada and parts of the north-central and upper eastern United States.
