VERIFY: Do low pressure systems circle the earth?

Let's verify how storms move around our earth.

KARE 11 meteorologist Jeff Edmondson was recently asked the question: "Do areas of low pressure circle the Earth?" The answer is complicated so lets talk about how they form.

Areas of low pressure typically develop along two different air masses, think of a large zone of warm air and a zone of cold air. For our area we see them develop in southern Canada and also in the United States along the Rocky Mountains.

So do they circle the Earth? The short answer is no. Most of the time these storms will dissipate and be absorbed by other cold fronts or new areas of low pressure that are created.

However, storms like Hurricanes can last a long time. Florence developed on August 31st and dissipated September 17th. The longest lived hurricane formed in the Eastern Pacific in early August of 1994, it then took a 31 day trip to the western Pacific Ocean where it dissipated as it moved towards Alaska.

Around the poles, areas of low pressure have a smaller area to travel and in this time lapse from the South Pole you can see individual storm systems form and dissipate but you don't see anything stay developed and circle the Earth.

So this time we can verify, no, storm systems do not circle the Earth.
