We have also seen various news reports commenting on what the term polar vortex means, as well as its history and use. 

At AMS, we have been publishing the “AMS Glossary of Meteorology” since 1959, and in that first edition, AMS did define the term ‘Polar Vortex.' We have since modified the original definition.
