This video tutorial covers the basics of air masses and fronts, starting with an overview of weather and climate differences. It explains the composition of the atmosphere and the role of air masses, which are large bodies of air with similar temperature and moisture characteristics. The tutorial details different types of air masses, such as Arctic, maritime, and continental, and their naming conventions. It then introduces the concept of fronts, which are boundaries between air masses, and describes the characteristics and effects of cold, warm, stationary, and occluded fronts on weather patterns.

What is the primary difference between weather and climate?

• Weather is constant, climate changes frequently.

• Weather is specific to a region, climate is global.

• Weather is short-term, climate is long-term.

• Weather is long-term, climate is short-term.
