Question

What are two differences between how isolated storms and cold front storms form?

Answer 1

In 1955, my father, a pilot and instructor in Belgium, showed us a Walt Disney film from 1943, made for military aviators, called: “Air Masses and Fronts.”

The animators used the following to illustrate the difference between a warm and cold front: The warm one was a paint brush drawn over a piece of paper. The cold one was the brush pushed over the paper, curling as it moved.

A warm front is simply warmer air that rises slowly over colder one. It is long, perhaps some hundred miles long. It is slack. As the air rises, condensing its moisture, it causes the formation of strato-cumulus, drizzle then rain.

The cold front is much steeper because now, the cold air moves in from under, lifting the warmer one over much shorter distance. The air is unstable and causes gusty and shifting wind, rain showers, perhaps some isolated thunderstorms but, since it is colder polar air, the visibility is much better.

Warm and cold fronts occur when a mid-latitude low pressure moves eastward along the polar front, pushing the warm one and pulling the cold one.

Since the cold one is steeper and moves faster, it soon joins the warm front causing what is called, an occlusion front. It can be a warm occlusion, if the cold front rises over the warm one, or a cold occlusion if the cold front lifts the warm one.

Hoppe this helps :) also next to do you mind adding a picture??
