The first 300 Club outside of Antarctica was established on January 30, 2019 near Minneapolis, Minnesota during a polar vortex. [6] With an outside temperature of −27 °F (−33 °C), three men heated their backyard sauna to 280 °F (138 °C) and sat inside for 10 minutes.
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 ...
When the polar vortex is strong, the mid-latitude Westerlies (winds at the surface level between 30° and 60° latitude from the west) increase in strength and are persistent. When the polar vortex is weak, high-pressure zones of the mid-latitudes may push poleward, moving the polar vortex, jet stream, and polar front equatorward. The jet ...
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.
The polar vortex is not synonymous with a cold snap. In fact, the stratosphere is 10 to 30 miles above the earth’s surface and above the polar jet stream and other systems that create most ...
Major SSWs occur when the winter polar stratospheric westerlies reverse to easterlies. In minor warmings, the polar temperature gradient reverses but the circulation does not, and in final warmings, the vortex breaks down and remains easterly until the following boreal autumn". [3]
Polar vortex. It's a phrase that becomes very popular has achieved buzzword status and is often used frequently during the winter as the Northern Hemisphere endures its coldest months of the year ...
The polar vortex drives fluctuations in winter temperatures in the middle latitudes. Climatologist Judah Cohen and others proposed climate change in the Arctic was causing the vortex to waver, bringing cold air south to the Midwestern United States , which was then replaced by warm tropical air.
