  1. CLIMATE

  2. WHERE IS THIS?

  3. CLIMATE v. WEATHER • Weather is day-to-day events • Climate is patterns of weather that can be expected in a given area

  4. CLIMATE • Interaction of atmosphere, lithosphere, • Two properties of the globe influence climate: Angle of the Ecliptic Coriolis Effect

  5. ANGLE OF THE ECLIPTIC

  6. CORIOLIS EFFECT • Because the earth rotates at a tilted angle (the ecliptic), a force develops that causes wind and water to move in a clockwise direction north of the equator • Counterclockwise south of the equator • At the equator itself is “doldrums” • Thus, the equator is a phenomenon with real physical effects on the globe (as opposed to the arbitrary Greenwich or Prime Meridian) • http://www.youtube.com/watch?v=4IIVfoDuVIw • http://www.youtube.com/watch?v=nX9nqpjRZgE

  7. FIVE FACTORS CREATE CLIMATE • Solar radiation • Precipitation • Winds • Ocean Currents • Elevation

  8. Solar Radiation

  9. PRECIPITATION – THINGS TO REMEMBER • Warm air rises • Cool air sinks • Warm air can hold more moisture than cool air • When warm air rises and cools, moisture is released • Where this occurs in nature, this situation causes precipitation

  10. PRECIPITATION: Convectional

  11. PRECIPITATION: OROGRAPHIC

  12. PRECIPITATION: FRONTAL

  13. FORMS OF PRECIPITATION • Rain • Freezing rain • Sleet • Hail • Snow • Frogs

  14. GLOBAL WIND PATTERNS

  15. JET STREAM – A HIGH-ALTITUDE STREAM OF AIR THAT CONTROLS WEATHER

  17. OCEAN CURRENTS • Circulate warm water from equator • Cold water from poles • Circular pattern or “gyres” • Where cold and warm currents meet, “upwelling” occurs, oxygenating the water and making great fishing conditions • Current patterns are still not fully understood

  18. OCEAN CURRENTS Circulation of warm and cold waters Current names

  19. EFFECT OF ELEVATION

  20. TYPES OF CLIMATES • NAMING SYSTEMS

  21. TROPICAL RAINY

  22. TROPICAL SAVANNA Irregular rainy and dry seasons Savannas flank rainforests http://www.justjared.com/2014/03/02/bette-midler-performs-wid-beneath-my-wings-at-oscars-2014-video/

  23. DESERTS –four scenarios (sometimes overlap) • Interior of continents • Cold currents off coast • Between 18 and 31 degrees latitude • Rain shadows

  24. INTERIOR DESERTS

  25. COASTAL DESERTS

  26. RAIN SHADOW DESERTS Painted Hills

  27. MEDITERRANEAN

  28. MARINE or MARINE WEST COAST RAINY! But mild Bright green on map

  29. HUMID CONTINENTAL

  30. HUMID SUBTROPICAL

  31. STEPPE Grasslands, mollisols Low precipitation

  32. SUBARCTIC

  33. POLAR
