What is climate
Human Influence on Climate
Long-term weather patterns of an area
Explain the difference between S.F. and Minneapolis?
Classifies climates based on average temperature and precipitation, taking into consideration vegetation.
Hawaii - http://www.georgedonna.org/Hawaiindx.htm
Constant high temperatures and lots of precipitation, the location of many rain forests.
30% of all land, location of many deserts (Sahara and Gobi), evaporation exceeds precipitation.
Subtropical high pressure systems bring warm, muggy summers and dry cool winters.
Constant flow of air from ocean brings mild winters and cool summers.
Italy - http://www.camigliano.it/eng/landscape.htm
Warm summers due to proximity to warm ocean water.
Temperature changes can be extreme from summer to winter, site of tropical and polar air mass collisions.
Year-around cold temperatures (warmest month average is less than 50ºF).
Tundra - http://www.bergoiata.org/fe/national-parks-american/10.htm
Little precipitation, many months of cold temperature, short growing season.
Penny Ice Cap - http://www.wholey.net/Auyuittuq/Auyuittuq.html
Form near the poles as a result of the small amount of solar radiation there.
Mt. Everest - http://www.muvaki.de/Tibet/
Unique climates due to extremely high elevations.
Localized climate that differs from the regional climate.
Features that act to increase temperatures in a microclimate
Ice Age - http://www.worldbook.com
Periods of time in which ice/glaciers cover vast amounts of Earth’s surface and temperatures decrease
Short-term period of climate change as a result of variations in daylight, temperature and weather.
Sunspots - http://theastropages.com/astroobjects/2000/20000306.htm
Large, dark, rapidly changing spots on the sun where solar radiation is blocked (possibly by magnetic field)
A change in the direction the N. pole faces. Eventually climates will shift when this wobbles to new direction.
Dust in the atmosphere can block solar radiation for several years, lowering temperatures.
The retention of heat in the atmosphere by gases that act like glass in a greenhouse.
