TIMELAPSE PHOTOS: Watch this polar vortex freeze us from space

The Gawker  blog,  Sploid , shows us, through NASA images, the "polar vortex" that's dropping our temps to record lows. 

The time-lapse photos are from NASA's Aqua and Terra  satellites.

According to NASA , a polar vortex is a wintertime feature of the stratosphere.

The vortex consists of winds spinning counterclockwise above the pole, the vortex varies in strength because of interactions with "planetary waves and global-scale disturbances that rise from the troposphere."

"The polar vortex acts like a big flywheel," Walter Robinson, a UI professor of atmospheric sciences, told NASA. 

Meteorologists at the Weather Channel say the cold front, displaying "life-threatening" temperatures in some locations, is the coldest front they've seen in decades. 

In Cincinnati, we are experiencing the coldest temps since 1996. The Tri-State is under a Wind Chill Warning until 5 p.m. Tuesday.
