The Climate today is dominated by global warming and change.
WHAT IS NEGATIVE ARCTIC OSCILLATION?
This is the oscillation and collapse of the Arctic Vortex, those fast moving jet streams around the North Polar Region.
What directly causes Arctic Vortex Collapse?
The name given is Sudden Stratospheric Warming (SSW) or sometimes, less articulately Arctic Atmospheric Warming (AAW)
“WARMING” leads to Arctic Vortex Collapse that leads to frigid arctic blasts from the North Pole across North America and Central Europe and Central Asia/China. Before 1998, there WAS NO ANNUAL ARCTIC VORTEX COLLAPSE! NONE! IT WAS RARELY ENCOUNTERED! We have given our children…every Winter… “this”, as part of Global Warming. it’s “new” and uniquely human.
Where specifically does this WARMING occur?
In a region of the Arctic Ocean called the Barents-Kara Sea Region, between Finland and Russia…
That is an absolute temperature of 5-10+ C in the waters of the B-K Sea Region at the Arctic Sea Ice Minimum in September. It is this WARM WATER AREA THAT STAYS WARM INTO FALL AND DISRUPTS THE ARCTIC VORTEX.
