east around Earth at speeds of 120 to 250 miles per hour,but can become dramatically wavier when it's disturbed by strong storm activity or encounters masses of hot or cold air.But this winter season, the meandering jet stream has not knocked the polar vortex off its pole,explained Lang. ...
This week's particularly cold outbreak may be explained by the relative lack of cold air so far this winter in the eastern U.S. Instead of the cold air bleeding south a little at a time, it's coming all at once. How cold will it get? The polar vort...
The MIPAS measurements reveal large variability in column ClONO2 at the edge of the polar vortex. For the measurements of January 27 and 31, 1993, the model experiments show that variability in ClONO2 observed over this period can be explained by polar stratospheric cloud processing and ...
Thepolar vortex-- a deep mass of frigid air that rotates around the top of the world -- has been knocked off balance, which means it's liable to spill cold air into the U.S. Although winter temperatures in the lower 48 stateshave generally been normalor w...
The polar vortex isn’t a storm, nor is it dangerous on its own. The only hazard associated with the polar vortex is the dangerously cold air that can spill out of the Arctic toward lower latitudes, which can last for long s...
Ok! (HealthDay)— As a giant polar vortex sweeps down over most of the United States, bringing with it temperatures so frigid that frostbite and hypothermia can happen within minutes, doctors have some advice for those who dare to venture outside. ...

A "swirling pool of extremely cold air located tens of thousands of feet in the atmosphere" has escaped the Great White North and plunged the Midwest and parts of the East Coast and South into subzero temperatures. This isthe Polar Vortex. ...
The modulation was in phase with the SQBO at 50 hPa maximizing during summer, which was explained by interhemispheric coupling to the Holton-Tan effect. Therefore, the low-latitude DW1 may be affected by the wave activities associated with the polar vortex modulated by QBO. 4.3 ENSO The CC ...
