Today, 04-17-09, I see an occluded front draped across the Midwest. I managed to figure out how to attach a picture that was on this website:
http://www.wunderground.com/US/Region/US/2xFronts.html
I pretty much understand what goes on when an occluded front occurs. The cold front, driven by the low pressure, catches up with the warm front and drives under the back end of the warm front. Its kinda like watching a snow plow driving under a huge wooden wedge.
I was wondering as to what happens to the air masses as the low pressure system drives the fronts along. Do they keep/maintain their boundaries? Or do they eventually mix and reform a new cold front?? Or does the warm air mass rise above the front edge of the cold front and eventually mix in??
Any suggestions or theories would be helpful, thanks.
