24 -1 AIR MASSES
Air Masses �Hot air rises Low pressure �Cold air sinks High pressure �Differences in pressure causes wind
How Air Moves �From poles towards equator � 3 wind belts in north � 3 wind belts in south
�Coriolis effect – winds are deflected by Earth’s rotation
Formation of Air Masses �Air mass – large body of air in which temperature and humidity are similar �Stationary or slow
�Form in: �Polar – cold and dry �Tropical ocean – warm and moist
Types of Air Masses �Classified by source region �Temperature and humidity �Ocean – maritime �Land - continental
Continental �Form over large land masses �Humidity low, dry �Stay in location for days or weeks
�c. P – continental polar Cold and dry �c. T – continental tropical Warm and dry
Maritime �Form over large bodies of water �Higher humidity �Bring rain or fog
�m. P – maritime polar Moist and cold �m. T – maritime tropical Moist and warm
North America Air Masses �Continental Polar c. P – cold and dry �From polar regions in Canada �Moves south-sotheast
�Maritime Polar m. P – cold and moist �From polar Pacific, polar Atlantic �Moves southeast, southwest-south
�Continental Tropical c. T – warm and dry �From US southwest �Moves north-northeast
�Maritime Tropical m. T – warm and moist �From tropical Pacific, tropical Atlantic �Moves northeast, north- northwest
