A quick but intense blast of Arctic air will barrel into the Northeast later this week to deliver quite a cold shock to the Northeast and neighboring Canada, AccuWeather meteorologists warn. The ...
The polar vortex is cyclical high-altitude winds that blow counterclockwise around the pole experiencing winter in the stratosphere, the next layer of atmosphere above the lowest, the troposphere ...
The polar vortex is a large area of low-pressure and cold air surrounding both of the Earth’s poles, according to the weather service. It always exists near the poles.
Behind the storm, an arctic blast from the polar vortex will send temperatures plunging to potentially record lows for much of the country. Behind the storm, an arctic blast from the polar vortex ...
The January 13–16, 2024 North American winter storm brought wide-ranging and significant impacts across much of the continental United States, particularly in the Southern regions of the country.
The polar vortex, which is a storm at the jet stream level of the atmosphere, has kept frigid air pent up above the Arctic Circle for much of the winter. When the polar vortex remains strong as it ...
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 term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex.
