Air Masses and Their Impact on Weather Patterns

The video tutorial explains air masses, defined by temperature and water vapor content, and their impact on weather in North America. It covers five major types: continental Arctic, continental polar, maritime polar, continental tropical, and maritime tropical. Each type's characteristics, such as being dry or humid, cold or hot, are influenced by their origin over land or ocean. The tutorial highlights how these air masses affect the climate and weather patterns in the United States, particularly the interaction between CP and MT air masses, which can lead to thunderstorms in the eastern US.

What are the two main characteristics that define an air mass?

• Humidity and wind speed
