This winter has been particularly snowy, with countless hits from polar
vortexes and
arctic blasts.
Colder temperatures and weaker high - altitude winds may make the
arctic polar
vortex even more intense in future winters and trigger greater ozone loss, says atmospheric scientist Paul Newman of NASA's Goddard Space Flight Center in Greenbelt, Maryland, although the losses probably won't approach those in Antarctica.
Mark Fischetti does a great job explaining the polar
vortex and how the belt that essentially keeps cold air tucked away up in the
arctic is loosening, resulting in the historic and extreme cold -LSB-...]
But a new analysis of more than six decades of daily temperature and snowfall data by Cohen and his team suggests
arctic heat waves may actually be linked to severe cold weather at lower latitudes... perhaps through the polar
vortex.
Long story short, the polar
vortex is the result of global warming changing the semi-permanent weather system over the
arctic regions resulting in movement of cold air masses from the
arctic region to parts of North America, such as Canada and, unfortunately, poor Buffalo.
Recent intrusions of cold
arctic air into the continents may be caused by aberrant behavior of the polar
vortex.
Only the Southwest, Hawaii, Alaska and South Florida will escape the grip of the upcoming
arctic blast that the polar

There has been a polar
vortex for as long as there has been an
arctic region.
However the polar
vortex remains over the
arctic regions as a great mass of swirling freezing air that persistently circulates counter-clockwise.

vortex, the movement of the air mass in the
arctic begins to change.
As long as the
arctic remains warmer than usual, the polar
vortex will continue to be a problem for years to come.
The Polar
Vortex shifts due to major warming in the
arctic polar region has been established climate science for over a decade now.
Recent research suggests that a warming
arctic may be contributing to cold snaps like this one in the Northeastern U.S. as a result of a weakened polar
vortex.»
