MTN News- Mid latitude cyclones are some of our biggest weather makers from the Fall through the Spring.  You might know them by a different name.

“Well a mid latitude cyclone would be more typically known as an area of low pressure.” said NWS Meteorologist Ben Schott.

This is not just any little low pressure area.

“And they can be pretty deep, not just at the surface although on a weather map you have a nice little “L” there.’ said Schott.

Mid latitude storm systems suck air into them at the surface.  This means that cold air from the North and warm air from the South are forced to collide because of the system.  This gives us weather fronts.

“And a lot of times they are associated with a cold front so you can have an extended line of rain and storms that extend from the south.” said Ben Schott.

In fact, you will never see a cold front attached to an area of high pressure.  This means, they do not make air masses collide and that is one of the reasons they are called “fair weather” systems. Meteorologists can identify a mid-latitude storm system on more than just a pressure map.

Dramatic swirls are especially detected just off the Pacific coast where friction does not destroy the circulation.
