The 2013–14 North American winter was one of the most significant for the United States and North America as a whole, due in part to the breakdown of the polar vortex in November 2013, which allowed very cold air to travel down into the United States, leading to an extended period of very cold temperatures.
According to the Associated Press, this will be the 10th time this winter that the polar vortex — a large area of cold air that spins over the North Pole — will drop into the U.S., delivering ...
Areas of the southeast will see some snowfall over the weekend. According to the National Weather Service Office in Atlanta, areas of northwest Georgia have about a 50% chance of seeing snowfall.
The north-central U.S. is suffering from the most extreme cold, with wind chills as low as -60 degrees for parts of the Dakotas, Montana and Minnesota.. Bismarck, North Dakota, recorded a low ...
A record low temperature at Dallas/Fort Worth International Airport of −2 °F (−19 °C) on February 16 was the coldest in North Texas in 72 years. [30] Power equipment in Texas was not winterized , leaving it vulnerable to extended periods of cold weather, leading to widespread power outages.
The 1985 North America cold wave [1] was a meteorological event which occurred in January 1985 as a result of the shifting of the polar vortex farther south than is normally seen. [1] Blocked from its normal movement, polar air from the north pushed into nearly every section of the central and eastern half of the United States and Canada ...
A stretched polar vortex event played a significant role in the Arctic outbreak that froze Texas in February 2021, killing more than 200 people, according to a 2020 study.
The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.
