Study Notes

Climate Definition

  • Climate is the weather pattern in a location over a long period (usually 30 years).
  • It's different from daily or weekly weather reports.
  • Climate factors affect how people dress and plan vacations.

Factors Determining Climate

  • Temperature: A key element in defining climate.
  • Humidity: The amount of water vapor in the air.
  • Distance from bodies of water: Impacts temperature and moisture.
  • Wind: Influences weather patterns and temperature.
  • Precipitation: The amount and type of rainfall or snowfall.
  • Topography: Land and water features (mountains, lakes, rivers) affect local climate.
  • Latitude: Distance from the equator affects temperature variations.
  • Elevation: Height above sea level influences temperature and precipitation.

Climate Groups

  • Scientists categorize climates into main groups based on factors.
  • There are five main climate groups.
  • A sixth (highland) climate group exists at high elevations, but not always considered in discussions.

Tropical Climates

  • Found near the equator.
  • Characterized by heat and heavy rainfall.
  • Examples include rainforests and savannas.
  • Rainforests are consistently warm and humid with abundant rainfall.
  • Savannas experience wet and dry seasons.

Dry Climates

  • Characterized by heat and low precipitation.
  • Often found in Africa and Australia.
  • Arid deserts receive less than a foot of rain annually.
  • Semi-arid grasslands receive more rain, supporting plant life.

Mild Climates

  • Experience warm and cold seasons, frequently near large bodies of water.
  • Mediterranean climates (e.g., Mediterranean Sea area): Warm summers, cool rainy winters.
  • Humid subtropical climates (e.g., parts of the US): Hot, humid summers, cold winters, rain in either season.
  • Marine climates (e.g., Seattle): Cold winters, abundant rainfall.

Continental Climates

  • Found in the Northern Hemisphere.
  • Experience distinct, contrasting seasons.
  • Humid continental climates (e.g., parts of the US): Warm summers, cold winters.
  • Subarctic climates (e.g., parts of Canada): Lower temperatures, longer winters.

Polar Climates

  • Located within the Arctic and Antarctic circles.
  • Tundra climates: Very cold with long winters but brief, plant-supporting summers.
  • Icecap climates: Temperatures are consistently below freezing with little precipitation on the ice-covered ground year-round.
