PPT-Weather Patterns

Air masses A huge body of air that has similar temperature humidity and air pressure at any given height is called an air mass The 4 major types of air masses that affect the weather in the United States are.

Low receives direct sun ray’s year round. Includes Equator, Tropic of Cancer, and Capricorn. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. 8. th. Grade Earth and Space Science. Class Notes.
