  1. Climate Factors

  2. Climate WEATHER, by definition, is the CURRENT state or condition of the atmosphere at aGIVENTIME and place. CLIMATE, on the other hand, describes the AVERAGE weather conditions that could be expected during a CERTAIN TIMEof year at a specific place. Climate is much less specific than a weather forecast…

  3. Climate is determined by two major factors

  4. CLIMATE FACTORS 1. Latitude- Low latitudes near tropics (Equator) are warmer.- High latitudes near poles are colder. 2. Prevailing Winds- Prevailing winds push air masses West to East across the country.- Winds blowing from the ocean bring moisture.Example: Seattle, Washington is very rainy. 3. Mountains Ranges- Mountains make air rise.- Rising air creates precipitation.

  5. 4. Distance to large bodies of water- Areas near water have smaller changes in temperature.Example: LA, California does not get very warm in the summer or very cold in the winter. • 5. Ocean Currents- Warm water current cause warm temperatures • - Cold water current cause cold temperatures NEXT

  6. 1. Latitude

  7. 1. Latitude PolarFrom 60-90 degrees longitude. Cold climate. TemperateFrom 23-60 degrees longitude. No extremes. In between temperature TropicsFrom 0-23 degrees longitude. Very warm temperatures. Polar Temperate Tropical Tropical Temperate Polar

  8. 2. Prevailing Winds If the winds move over water – moist air is brought to the region. If the winds move over land – dry air is brought to the region.

  9. - Faces the wind- Air rises- Air cools and condenses- Precipitation occurs Windward Side Air - Downwind- Air sinks- Air warms and dries- No precipitation Leeward Side 3. The Rainshadow Effect DRY SIDE WET SIDE Mountain

  10. How does the RainshadowEffect affect climate? Windward Side: ___________ Leeward Side: _____________ cool, moist warm, dry

  11. 4. Distance from Large Bodies of Water(oceans, seas, large lakes) • oceans hold their heat longer creating mild coastal climates

  12. 5. Ocean Currents • Warm-water currents warm coastal climates • Cold-water currents cool coastal climates.

  13. Global Ocean Currents
