(FOX Weather) "There isn’t a one-to-one correlation between what’s happening with the polar vortex and our weather, and also, there’s a delay," Judah Cohen, Ph.D. and an atmospheric and environmental scientist who studies the polar vortex, told FOX Weather. "So, you’ve been talki...
Few phrases in a weather forecast can send a chill down even the winter-hardiest spine quite like the polar vortex. The polar vortex isn’t a storm, nor is it dangerous on its own. The only hazard associated with the polar ...
With a piece of the Polar Vortex camped out in the North Central U.S.(near historic cold for this time of year), storm systems have been like a parade traversing the periphery of the vortex. This has brought heavy snow and ice to the Deep South, with major disruptions to travel and ...
While the polar vortex in the mid-stratosphere tends to recover quickly after these disturbances, any effects on the tropospheric jet stream and its weather patterns couldpotentially stick around for up to 6 weeksafter the vortex is disrupted.This “loads the dice” for potential arctic outbreaksov...
Extreme polar vortex events known as sudden stratospheric warmings can influence surface winter weather conditions, but their timing is difficult to predict. Here, we examine factors that influence their occurrence, with a focus on their timing and vertical extent. We consider the roles of the trop...
High above the North Pole, thepolar vortex, a fast-spinning whirl of frigid air, is doing a weird shimmy that may soon bring cold and snowy weather to the Eastern U.S., Northern Europe and East Asia for weeks on end, meteorologists say. ...

While El Niño is still just as strong, a major change in the jet stream pattern is already underway. One of the keys to the pattern change is the polar vortex which is expected to split into two parts, and one piece is...

The polar vortex(极地涡旋) — a rotating(旋转的) part of cold air — becomes active as the temperature rises there. So lots of cold Arctic air then goes southward. Will this winter be much colder? The official forecast(预报) said a cold winter is possible. Northern China may see more ...
