Exploring Air Masses and Fronts

The video explains the excitement of a snow day caused by a sudden snowstorm. It introduces the concept of air masses and fronts, detailing how cold and warm fronts form and affect weather. The video describes the four types of air masses in the US: maritime polar, continental polar, maritime tropical, and continental tropical. It explains how cold fronts lead to intense weather like snowstorms, while warm fronts result in lighter, steady precipitation. The video concludes with a recap of these concepts.

What is a cold front?

• A boundary where two warm air masses meet

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

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

• A boundary where two cold air masses meet
