During the 2014 January polar vortex, more than 20 people across the country died from the cold as places like Georgia — which rarely see serious cold — dealt with lows under 10 degrees ...
Prior to the events of January 2014, several studies on the connection between extreme weather and the polar vortex were published suggesting a link between climate change and increasingly extreme temperatures experienced by mid-latitudes (e.g., central North America). [89]
The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes ...
'Chicago Beach Keeps Locals Warm During Polar Vortex' – video new report from Voice of America. Chicago river frozen during 2019 polar vortex February 1, 2019 In the Chicago area , temperatures plummeted as low as −23 °F (−31 °C) at O'Hare International Airport on January 30, with a windchill of −52 °F (−47 °C).
Polar vortices also exist on other rotating, low-obliquity planetary bodies. [1] 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 ...
New York City had its first measurable snow (0.1 of an inch or greater) early Wednesday and other locations, such as Philadelphia and Washington D.C. were teetering on the edge of measurable snow.
The cold was caused by a southern migration of the polar vortex, likely caused by a sudden stratospheric warming event that occurred the prior month. Temperatures fell as much as 25–50 °F (14–28 °C ) below average as far south as the Gulf Coast .
The polar vortex, which is a storm at the jet stream level of the atmosphere, has kept frigid air pent up above the Arctic Brief visit from polar vortex to bring record-challenging cold to ...
