1. Is there a difference?

2. Climate Vs. Weather Climate Long-term weather patterns of an area Weather Current state of the troposphere Short term variations

3. Climatology The study of Earths climate and the factors that affect past, present, and future climatic changes

4. Normals Standard values for a location Average values over a long period of time

5. What Causes Different Climates? Topography Coastal Regions, areas near water, are warmer in the winter and cooler in the summer Latitude

6. Equator Tropic of Capricorn Tropic of Cancer Arctic Circle Antarctic Circle 66.5° N 23.5° N 23.5° S 66.5° S 0°

7. Tropics Temperate Polar Temperate

8. Climate Regions Tropics Most solar radiation, generally warm Between Tropics of Capricorn and Cancer Temperate Between 23.5 and 66.5 North and South Mild temperatures Polar 66.5 North and South to the Poles Cold Temperatures

9. Koeppen Classification System Classified based on temperature and amount of precipitation Tropical Dry Mild Continental Polar

10. Climate Change

11. Long-Term Climatic Change Climates change over extremely long periods of time Ice Ages – Periods of extensive glacial coverage Most recent ended 10,000 years ago Temps dropped 5°C

12. Short-Term Climatic Change Caused by regular variations in daylight, temp, and weather patterns Examples: Seasons El Nino (Warm ocean current)
