NASA’s AIRS captures early 2014 Arctic surge
(KTVI)- NASA’s Atmospheric Infrared Sounder, AIRS, really picked up the dangerous Arctic cold that invaded much of the nation last week. The coldest air is shown by the deep purple color.
You can clearly see the so-called Polar Vortex, the cold air moving out of the Arctic through Canada and off to the south. The coldest temperatures in the movie are around minus 18 degrees Fahrenheit.
The shot of deep cold air was the first significant weather event of 2014, occurring right at the start of the new year.
Notice how warm Alaska and northern Europe were during this cold period over the eastern United States.
AIRS provides a three-dimensional look at Earth’s weather and climate and is an instrument on NASA’s Aqua spacecraft.
