NASA Video Shows Polar Vortex 2019 Moving to Spread Frigid Air Across US Midwest
NASA’s Atmospheric Infrared Sounder on the Aqua Satellite shows a visual depiction of the dramatic and deadly cold snap.
The world is only talking about the frigid temperatures at the Midwest that have put part of the United States into a halt. An unusually cold Arctic air mass called a polar vortex is responsible for the severe weather in the areas forcing the temperature to plunge below zero degrees Fahrenheit. You do not really have to live in the US Midwest to have heard about the polar vortex. The situation is very severe in those areas. A new video by the National Aeronautics and Space Administration (NASA)’s Atmospheric Infrared Sounder (AIRS) on the Aqua Satellite shows a visual depiction of the dramatic and deadly cold snap.

NASA explained that the lowest temperatures are shown in purple and blue and range from -40 degrees Celsius to -23 degrees Celsius. As the data series progresses, you can see how the coldest purple areas of the air mass scoop down to the United States.
The Aqua Satellite was launched in 2002. NASA’s Jet Propulsion Laboratory manages the AIRS and AMSU instruments in Pasadena, California. AIRS is capable of producing detailed heat maps over a vast geographical area. NASA used this equipment to monitor the change in temperature that is created by the polar vortex. Meanwhile, it is reported that the Midwest is expected to gradually warm back up over the next few days and return to temperatures more similar to what the residents would expect for early February.
