Study Notes
Air Masses Overview
- An air mass is a large body of air with uniform temperature, humidity, and pressure at a given height.
Classification of Air Masses
- Air masses are classified by temperature: warm or cold.
- They are also classified by humidity: wet or dry.
Temperature Characteristics
- The temperature of an air mass is influenced by its geographic location.
Tropical Air Mass
- Forms in tropical regions; characterized by warmth.
- Associated with low pressure due to the rising of warm air, leading to lower density.
Polar Air Mass
- Forms at the poles; characterized by cold temperatures.
- Associated with high pressure due to the sinking of cold air, leading to higher density.
Humidity Influences
- Humidity of an air mass is determined by its formation over either water (humid) or land (dry).
Maritime Air Mass
- Forms over oceans, resulting in high humidity.
- Water evaporation contributes to the moist characteristic of this air mass.
Continental Air Mass
- Forms over land and typically has low moisture content, making it dry.
Terminology of Air Masses
- Cold air mass is synonymous with polar air mass.
- Warm air mass is synonymous with tropical air mass.
- A dry air mass is known as a continental air mass.
- A wet air mass is identified as a maritime air mass.
Specific Types of Air Masses
- Maritime tropical: wet and warm air mass.
- Continental tropical: dry and warm air mass.
- Maritime polar: wet and cool air mass.
- Continental polar: dry and cool air mass.
Visual Understanding
- To comprehend air masses in North America, consult a map showcasing their distribution.
