Atmosphere & Climate

Inversions - reverse of normal lapse rate It's warmer the higher you go in elevation traps air to create smoggy, foggy and colder condition large scale and localized phenomenon

• large-scale sinking air - associated with high pressure systems
  • compression adds to heating of upper air
  • Mexico City
    
    
• advectional cooling - associated with upper air horizontal flow of cool air that sweeps beneath warmer air, such as cold ocean air
  • Los Angeles Basin
    
    
• surface inversions - associated with cold winter nights
  • radiational cooling - land cools rapidly and cools surface air
  • cold-air-drainage cooling; displaces warmer air aloft
  • fog arises
  • Sacramento Valley
