Factors of Climate

  1. 1. Factors of Climate What is climate? What factors determine climate?
  2. 2. What is Climate? Weather - state of the atmosphere at any given time or place. (what’s it like right now) Climate - the weather conditions of an area over a long period of time. (average weather over time)
  3. 3. #1 The Sun Source of all light and warmth The more direct sunlight = warmer temperatures The Earth’s axis, tilt, & rotation determine how much light we get and when.
  4. 4. #2 Latitude Lines Arctic Circle = Polar Region Tropics from 23.5N to 23.5 S Mark regions where sun hits Mid-Latitudes = Temperate Region
  5. 5. Simple summary of climatic zones: ● ● ● ● ● ● Polar - very cold and dry all year Temperate - cold winters and mild summers Arid - dry, hot all year Tropical - hot and wet all year Mediterranean - mild winters, dry hot summers Mountains (tundra) very cold all year Write these on the back of your organizer!
  6. 6. #3 Ocean/Wind Currents Can bring warming or cooling effect on the climate. Tropics = Warm Polar = Cool
  7. 7. #4 Elevation The higher you go, the cooler it gets. Reason: The air is less dense and cannot hold heat as easily.
  8. 8. #5 Precipitation The amount affects how arid or wet the climate is.
  9. 9. Distance from the sea (continentality) Land heats and cools faster than the sea. Therefore coastal areas have a lower temperature range than those areas inland. On the coast winters are mild and summers are cool. In inland areas temperatures are high in the summer and cold in the winter.
  10. 10. Aspect Slopes facing the sun are warmer than those that are not. Thus south facing slopes in the northern hemisphere are usually warm. However, slopes facing north in the southern hemisphere are warmest.
