  1. CLIMATE

  2. CLIMATE 3 MAIN TYPES • POLAR --- high latitude – 60 – 90 degrees N/S. Very low Temps. • Temperate (Middle-Latitude) --- middle latitude 30 – 60 degrees N/S. Temps vary greatly. • TROPICS --- low latitude 0-30 degrees N/S. Very high temps.

  3. CLIMATOGRAPH

  4. CLIMATE CONTROLS • LATITUDE (angle of incidence) • ALTITUDE • MOUNTAINS (barriers) • OCEAN CURRENTS • WATER VS. LAND • CYCLONIC STORMS • PRESSURES

  5. RAINFOREST (TC) • Tropical Climate • Little temp. difference (hot) • Rainfall greater than 100 inches due to convection (transfer of heat through movement of a fluid) • Thick vegetation • ex. Zaire, Amazon, Indonesia, Malaysia, Sumatra

  6. RAINFOREST

  7. RAINFOREST

  8. DESERT (TC) • Tropical Climate • Located near 25-30 degrees (High Pressure) • High temps, low humidity, clear • rainfall less than 10 in. • sparse vegetation • ex. W. USA, Gobi (Asia), Sahara (Africa), Middle east

  9. DESERT

  10. Desert

  11. SAVANNA (TC) • LOCATED NEAR AREAS OF LOW PRESSURE • SUMMER – WARM DAY AND NIGHT • WINTER WARM DAY AND COOL NIGHT • WET/DRY SEASONS • VEGETATION – TALL GRASS WITH SCATTERED TREES • AFRICA, S. AMERICA, S. FLORIDA

  12. SAVANNA

  13. SAVANNA

  14. STEPPE (MLC) • MIDDLE-LATITUDE CLIMATE • LOCATED NEAR DESERTS • WARM TEMPS. • 10-20 IN OF RAINFALL • POLISH WORD MEANING “GRASSLAND”

  15. STEPPE

  16. MARINE WEST COAST (MLC) • Found along west edge of continents • Temp is warm and mild • Rainfall is 30-60 in. • Heavy vegetation on windward side of mts. • controls include mountains and ocean • Ex. N.W. coast of US. N.W. Europe

  17. MARINE WEST COAST

  18. MIDDLE LAT. DESERT • Found in interior of continents • Dry and warm • Little precipitation. 10 – 20 in. • winter season – cold • Midwest

  19. MIDDLE LAT. DESERT AND STEPPE

  20. MEDITERRANEAN (MLC) • S.W. coast of continents, along horse lat. • warm dry summers. mild winters • summer is dry (H pressure) • winter rainfall due to shifting High pressure • “Best climate” clear skies, low humidity • S. Cali, S. Africa, Shores of mediterranean sea.

  21. MEDITERRANEAN

  22. MEDITERRANEAN

  23. HUMID SUBTROPICAL (MLC) • S.E. edge of continents 30-40 degrees lat. • Extremes in temps. 0-100 usually mild winters • rainfall 30-65 in a year. • Heavy plant growth and forests • cyclonic storms are controlling factor • S.E. U.S.

  24. HUMID SUBTROPICAL

  25. HUMID SUB TROPICAL

  26. HUMID CONTINENTAL (MLC) • N.E. area of continents • EXTREMES in temps. summer is warm and humid, winter is cold with snow • rainfall – 30 in. • cyclonic storms

  27. HUMID CONTINENTAL

  28. MOUNTAIN • Rockies, Appalachians • Temperature, pressure decrease with altitude • Precipitation on windward sides • Vegetation becomes sparse with increase in altitude.

  29. MOUNTAIN

  30. SUBARCTIC (PC) • 50- 65 degrees lat. • Cold winters, short summers • 10-20 in of rainfall • Taiga Forest (pine) • Biggest climate in N. America • Greatest temp range. -59 to +70

  31. SUBARCTIC

  32. SUBARCTIC

  33. TUNDRA (PC) • Boarders lands of icecap • VERRRRRRY cold • 10 in. of precipitation • Permafrost, small shrubs, moss, lichens • found only in northern hemisphere • Eskimos • 9 months avg. below freezing.

  34. TUNDRA

  35. ICECAP (PC) • N.P. and S.P. • Temp never above freezing • snow maybe 2-3 miles thick • official low - -126.9 degrees F. • Few inhabitants • Land of the six month sun.

  36. ICECAP
