When it remains strong and well positioned, it helps confine the coldest air near the pole. But when it shifts southward, Arctic air can spill into Canada and the northern United States, driving temperatures sharply lower. In non-technical terms, the fluid near the center of the vortex circulates faster than the fluid far from the center.

When most people hear the term polar vortex, they think of extreme cold, dangerous wind chills and relentless winter weather. While the polar vortex can certainly deliver frigid air, it doesn’t always mean constant storms and widespread disruptions. During winter in the Northern Hemisphere, the polar vortex can often expand and send cold air south, often referred to as an arctic blast, a phenomenon that occurs regularly at this time of year. The phenomenon can send chilly temperatures to regions and areas in the south that don’t usually experience the cold. Vortex Engineering is an innovative and leading provider of Automated Teller Machines (ATMs) and multi-vendor ATM management software products. With a strong foundation built on years of focused research & development, Vortex has revolutionized the ATM industry with its unparalleled cost-effective range of green ATMs to achieve the highest return on investment (ROI).

• A good example of a vortex is the atmospheric phenomenon of a whirlwind or a tornado or dust devil.
• The polar vortex will bring below-freezing temperatures to the Midwest, Mid-Atlantic and the South, USA TODAY previously reported.
• As water flows out of a small opening in the bottom of the basin or reservoir, it forms what is called a whirlpool.
• Although there is still a lot of unknown information regarding Himawari’s Nine-Tails and how she acquired the chakra, it will all be cleared up in due time.

The polar vortex over Antarctica and its adjacent seas is isolated from air outside the region by the polar-front jet stream in the Southern Hemisphere, which circulates between approximately 50° and 65° S over the Southern Ocean. The Antarctic polar-front jet stream is more uniform and constant than its Arctic counterpart, because Antarctica is surrounded by ocean rather than a mix of land and water. As a result, land-ocean temperature contrasts underneath the jet stream in the Antarctic are not as great as those in the Arctic. In addition, mountains capable of deflecting energy into the jet stream are fewer and distant, so the development of large Rossby waves is less frequent than in the Northern Hemisphere.

It is also a good idea to check the items in your home and car emergency kits at the beginning of each winter season to ensure you are prepared for any type of hazardous winter weather. The meteorologists said the polar vortex system is set up due north of Michigan over Canada’s Hudson Bay. It’s at least partly responsible for the frigid temperatures around the region that contributed this week to a 100-vehicle pileup in southwest Michigan and led the city of Detroit to declare a cold weather health emergency. A vortex can be observed in the spiraling motion of air or liquid around a center of rotation. A good example of a vortex is the atmospheric phenomenon of a whirlwind or a tornado or dust devil. Tornadoes develop from severe thunderstorms, usually spawned from squall lines and supercell thunderstorms, though they sometimes happen as a result of a hurricane.

After the weekend winter storm, temperatures will drop below 10 degrees in most of the North East and northern U.S. «The polar jet stream usually contains that Arctic air to the north,» said Kevin Kacan, a meteorologist at the National Weather Service’s Detroit regional office. «But when there’s a disturbance that breaks that northern track of the jet stream, it allows air to sink down into the northern U.S.» The center of the stretched polar Vortex game vortex will be somewhere above Duluth, Minnesota, by Friday morning, ushering in “long-lasting brutal cold,” Maue said. Temperatures in the North and Midwest will get about as cold as possible, even down to minus 25 or 30 degrees Fahrenheit (minus 32 to minus 34 degrees Celsius), Maue said. The average low temperature for the Lower 48 states will dance around 11 or 12 degrees (minus 12 to minus 11 degrees Celsius) on Saturday, Sunday and Monday, Maue said.

Our cutting edge technology based products improve the bottom-line of our customers. “I think people are underestimating just how bad it’s going to be,” said former National Oceanic and Atmospheric Administration chief scientist Ryan Maue, now a private meteorologist. «Potentially hundreds of thousands of people may go without electricity and heat for days,» said Jonathan Porter, AccuWeather’s chief meteorologist. The system could affect over 150 million people in over two dozen states over the weekend of Jan. 24 and 25, according to AccuWeather.
