What is the difference between a cold front a warm front a occluded front and a stationary front?

Answer 1

Air masses are categorized by their humidity and temperature. Fronts are a boundary that forms when air masses meet.

Cold Front

• *as cold air moves forward, warm air is pushed upward*

• cold air mass displaces a warm air mass

• cumulus and cumulonimbus clouds form

• Usually produce thunderstorms with heavy percipitation

• Move into regions quickly

• Breif, heavy storms are likely

• After storms, the air is cooler and often very clear

Warm Front

• *warm air gradually moves up and over a mass of denser, colder air*
• warm air mass overtakes cold air mass
• nimbostratus clouds form
• constant rain/snow (for at least 24 hours)
• move more slowly than cold fronts
• bring many hours of steady rain/snow
• After the front passes, it is often warmer

Answer 2

Warm front: a red curvy line with semi circles on the side the front is advancing towards. Cold front: blue curvy line with triangles on the side that the front is advancing towards. Stationary front: red and blue line with red semi-cirlces on one side and blue triangles on the other.

Answer 3

A warm front occurs when cooler air retreats and warmer air advances.

A cold front occurs when cooler air advances, pushing warmer air away.

An occluded front occurs when a cold front catches up with a warm front, sending the warmer air aloft.

A stationary front occurs when warm and cold air meet, but neither air mass advances.
