  1. FactorsThat AffectClimate Weather vs. Climate Creating Seasons LAME COWS

  2. Weather vs. Climate • Weather • condition of the atmosphere in one place during a short period of time. • Climate • weather patterns typical for an area over a long period of time.

  3. Creating Seasons • Revolution • Orbit around the sun • Rotation • Earth rotates on its axis - 24 hours – from west to east. • Axial Tilt • Earth is tilted at 23 ½ ° differing the amount of sunlight throughout the year.

  4. Creating Seasons • Equinox • March 21 and September 23, suns rays on the equator. Spring and Fall • Solstice • June 21, north hemisphere receives the most sun, Dec 22 Southern hemisphere receives most sun. Summer and Winter.

  6. Latitude AirPressure MountainBarriers Elevation ContinentalLocation OceanCurrents WindCurrents Storms Eight Factors That Affect Climate

  7. Latitude • Major change to climate • Change as you move North to South • Equator = direct rays = hot • Poles = indirect rays = cold

  8. AirPressure • Caused by unequal distribution of earths heat. • LP = warm, moist air rises → forms clouds → storms. • HP = cold dry air → sinks → stable and clear.

  9. MountainBarriers • a.k.a. - Orographic Precipitation • a.k.a. – Rain Shadow Effect • Windward side • Warm, moist air → up windward side → cool moist air drops precipitation • Leeward side • Warm dry air → down leeward side → little to no rain.

  10. Elevation • How far above sea level you are. • Every 1,000 feet temperature changes 3.5°F.

  11. ContinentalLocation • Water heats and cools more slowly than land. • Coastline areas have stable temperature. • Interiors of continent have extreme temperature changes.

  12. OceanCurrents • Warm-water currents -equator to the poles. • Cold water currents - poles to the equator. • Coriolis effect – The currents circular patterns are opposite of one another due to the Earth’s rotation. • Northern Hemisphere – clockwise • Southern Hemisphere – counter clockwise.

  13. WindCurrents • Air in high pressure rushes into areas of low pressure – this causes wind. • Helps to distribute earth’s heat. • Coriolis effect

  14. Storms • Clashes between warm and cold air masses • Hurricanes – tropical storms moving heat from tropics. • Tornadoes – powerful funnel shaped spiraling air.

  15. Homework • Read page 58 in your textbook, section titled “The Greenhouse Effect”. (total of 6 paragraphs) • Answer the following questions, • Why is the earth’s atmosphere referred to as being like a greenhouse? • What human activities have caused there to be high levels of CO2 in the atmosphere? • Analyze the diagram on page 70. • Answer questions 1-4 in complete sentences.
