Air Masses 1. Air Mass- large body of air that has the similar moisture and temperature throughout it 2. An air mass gets it moisture and temperature characteristics from the area over which it forms.

Air Masses 3. Masses are represented with a two letter symbol. 4. First letter represents moisture characteristics 5. Second symbol represents temperature characteristics

Symbols Types of Symbols 6. Maritime (m)- forms over water; wet 7. Continental (c)-forms over land; dry 8. Polar (P)-forms over polar regions; cold 9. Tropical (T)- forms over the Tropics; warm

Cold Air Masses 3 polar air masses influence weather

Northern California/Southern California

Warm Air Masses 4 warm masses influence weather
