The path of the Jet Stream changes every moment, and is a uniquely different pattern on any given day. It generally follows an annual cycle - the wind speed and extent of coverage is much greater in the Winter and much less in the Summer. This seasonable variability of the Jet Stream over North America is illustrated in the simplified black and white maps from 2017. The animation shows the jet stream over North America for one full year. The original Jet Stream map of the entire Northern Hemisphere from April 18th, 2005 that has been translated into bronze, can also be seen below.
