  1. Early Greek View of Earth’s Climate

  2. Köppen climate classification --average monthly temp.

  3. Chart for Determining Köppen classification

  4. The Köppen system uses a series of letters to designate climate:

  5. Koppen 2nd and 3rd letter designations A climates m – short dry season (monsoon) s – dry summer (rare) “Night is winter in the tropics”—

  6. CLIMATE CLASSIFICATION “Genetic” ClassificationKöppen symbol --warm, humid year-round --controls: ITCZ mT air masses --warm, humid year-round; short dry season --Controls: ITCZ, on-shore winds in rainy season

  7. --longer dry season than monsoon --Controls: ITCZ in rainy season (“summer”) STH in dry season (“winter”)

  8. Main control on A climates:

  9. B climates S– potential evapotranspiration exceeds precipitation W– potential evapotranspiration is 2x precipitation

  10. --hot, dry year round --Controls: STH cT air masses --not as dry as #4 --Controls: same as #4 -- seasonal rainfall due to either ITCZ or Mid-latitude cyclones

  11. --Controls --cold ocean currents --e.g. Atacama Desert, Chile --colder than #5 due to higher latitude --Controls: long distance to moisture source; rainshadows --similar to #7, but with more summer convective rainfall
