In Australia, the polar vortex, known there as a "polar blast" or "polar plunge", is a cold front that drags air from Antarctica which brings rain showers, snow (typically inland, with blizzards occurring in the highlands), gusty icy winds, and hail in the south-eastern parts of the country, such as in Victoria, Tasmania, the southeast coast of ...
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 ...
Beginning Saturday, the polar vortex began to dip down into the northern tier of the U.S., dropping temperatures into the single digits. Wind chills dropped into the negative teens for that region.
The disturbances in the polar vortex also caused "massive" quantities of freezing air to be pushed toward the equator, causing unseasonably colder temperatures and cold fronts throughout the Southern Hemisphere, including the Southern Cone of South America, New Zealand, and Australia. [4]
" The polar vortex is defined as a mass of cold air that is tightly bound to polar regions by strong counterclockwise winds known as the polar jet stream," Thornton explained.
The potentially life-threatening cold is due to the disrupted polar vortex. The FOX Forecast Center said a lobe of the polar vortex will dip to the south and move into the U.S. this weekend and ...
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 ...
