Climate Verses Weather Is there a difference?
Climate Vs. Weather • Climate • Long-term weather patterns of an area • Weather • Current state of the troposphere • Short term variations
Climatology • The study of Earth’s climate and the factors that affect past, present, and future climatic changes
Normals • Standard values for a location • Average values over a long period of time
What Causes Different Climates? • Topography • Coastal Regions, areas near water, are warmer in the winter and cooler in the summer • Latitude
Arctic Circle 66.5° N Tropic of Cancer 23.5° N Equator 0° Tropic of Capricorn 23.5° S Antarctic Circle 66.5° S
Polar Temperate Tropics Tropics Temperate Polar
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
Koeppen Classification System • Classified based on temperature and amount of precipitation • Tropical • Dry • Mild • Continental • Polar
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
Short-Term Climatic Change • Caused by regular variations in daylight, temp, and weather patterns • Examples: • Seasons • El Nino (Warm ocean current)
