  1. Chapter 8: Climate Wladimir Köppen 1846-1940

  2. A Climates—no seasons, constant temperature, varying precipitation

  3. Af climate—Tropical Rainforest

  4. Am Climate—Tropical Monsoon

  5. Aw Climate—Tropical Savanna Why the dry season?

  6. C Climates—mild winters, varying precipitation San Francisco, CA Chengdu, China Columbia, South Carolina Cfb Csa, Csb Cfa Cwa Any pattern to where C climates are located? Why do C climates extend into the upper latitudes on west coasts (northern hemisphere) but not on east coasts?

  7. Cfa—Humid Subtropical Cwa—Humid Subtropical, dry winter

  8. Cfb—Marine West Coast Rain all year, cool Wettest climate in the mid-latitudes

  9. Csb—Mediterranean, mild summer

  10. CsavsCsb climates—Mediterranean hot summer & mild summer climates—can exist as close as 20 miles from each other!

  11. D climates—severe winter (at least one month average below freezing) Verkhoyansk, Russia Churchill, Manitoba Moscow, Russia New York, NY Dailan, China Dfa Dfb Dfc, Dfd Dwc, Dwd There are no D climates in the southern hemisphere—why?

  12. Dfa Humid Continental DwaHumid Continental, dry winter

  13. Dfb Humid Continental Cool Summer

  14. Dfc--Subarctic

  15. Dwd—most severe Subarctic

  16. No summers, almost no precipitation

  17. Polar Tundra Climate

  18. Musk-ox eating lichen on the tundra of Greenland

  19. Polar Ice Cap Climate

  20. B Climates—deserts & steppes Areas with relatively high annual precipitation can be deserts (or steppes)if temperatures are high. Albuquerque, NM ArRiyad, Saudi Arabia BS (mid-latitudes)—steppes Transitional ZonesCool or hot summers BSH, BSK BW (subtropics)—deserts Cool or hot summersBWh, BWk

  21. Why such extensive aridityin the western U.S.? Mojave Desert Atacama Desert

  22. In addition to the influence of the STH, deserts are determined by: --mountain barriers (think of the western U.S.) --colder ocean currents (think of the coast of Chile)

  23. Atacama Desert, ChileDouble Rain Shadow

  24. Proximity to cold ocean currents intensifies aridity, but can also produce important coastal fog belts.

  25. BWh Subtropical Desert Hot summers BWk Mid-latitude desert Cool summer

  26. BSh—Usually just outside of the hot deserts of the tropic These are transitional climates between desert and more humid areas. Precipitation is usually less than 23.6 inch/year. On outskirts of Sahara Desert and in Middle East.

  27. BSk—Usually poleward of 30° and the mid-latitude deserts. In these climates, precipitation is usually convective, so occurs in summer. However, in places like Semey, there are cyclonic storms that impact the area, they just do not bring much moisture with them. BSk— mid-latitude cold steppe climates
