Exploring Weather Fronts

The video explains the excitement of a snow day caused by a snowstorm, which is a result of a cold front. It introduces the concept of air masses, which are large bodies of air with uniform temperature and moisture. There are four types of air masses in the US: maritime polar, continental polar, maritime tropical, and continental tropical. The video describes how cold fronts occur when a cold air mass pushes a warm air mass upward, leading to heavy weather like snowstorms. In contrast, warm fronts occur when a warm air mass overtakes a cold one, resulting in lighter, steady weather. The video concludes with a recap of these concepts.

What is a cold front?

• A boundary where two cold air masses meet

• A boundary where two warm air masses meet

• A boundary where a cold air mass pushes a warm air mass up

• A boundary where a warm air mass pushes a cold air mass up
