Air Masses:

• What is an air mass?

  • Large bodies of air with similar temperature and moisture characteristics

• How do we classify them?

  • Based on source region and temperature

• What effect do they have?

  • Influence weather patterns and bring changes in temperature, humidity, and precipitation
