12.1 notes: The Causes of Weather Main Idea 1: Weather is affected by winds carrying air masses.

Air Masses Characteristics Temperature: Determined by the amount of solar radiation received & the heat capacity of the area over which it forms.

Air Masses Characteristics Humidity: Measurement of moisture content in the air.

c= Continental m= Marine Four Major Types of Air Masses: (T) tropical cT Warm, Dry mT Warm, Wet (P) polar cP Cool, Dry mP Cool, Wet

Long term variations of the weather in a region. It’s the average of 30+ yrs. or more of “weather”. Weather vs. Climate: The current state of the atmosphere. Ie.. short-term variations in a region.

Balancing The “Budget”: Due to continual air movement & ocean circulation, heat energy is constantly moving between air, land, & water. Heat is always being redistributed around the globe.

The Ocean’s Conveyor Belt: The Earth’s “Air conditioner” The Earth’s Major Winds

Main Idea 2: The large water or land area over which an air mass forms is called the source region.

Air Masses: Describe: A large body of air that takes on characteristics of the area over which it forms.

Classify Air Masses: . Warm, dry = formed over land, near tropics. Cold, dry= formed over land, near poles. Warm, wet= formed over ocean, near tropics. Cold, wet = formed over water, near poles. .

Source Regions: Ex A: A huge, empty parking lot at Disney World in July = hot, dry air mass! Ex B: Malaspina Glacier near the ocean= cold, wet.

Air Mass Modifications: Always on the Move: Air masses do not stay in one place forever! Describe Modification: When an air mass moves over new land or water, it acquires new characteristics from the new surface beneath it.
