Types of Air Masses and Their Impact on Weather

The video explains how weather is influenced by air masses, which are large parcels of air with specific characteristics. Air masses are classified based on their location (continental or maritime) and source region (Arctic, Polar, or Tropical). These classifications help predict weather patterns, as maritime air masses bring moist conditions while continental ones bring dry weather. The video also covers how air masses move and interact, leading to phenomena like convectional and orographic lifting, which can form clouds and precipitation. Fronts, where different air masses meet, can cause significant weather changes, including storms.

What is a continental air mass?

• An air mass found in polar regions

• An air mass found in the tropics

• An air mass found over land
