LATITUDE

• (You can refer back to map on p. 52
• when studying!)
• High Latitudes
• N.of the Arctic circle also
• S. of the Antarctic circle
• They have ONE Season - Cold (exAntarctica)

4
LATITUDE

• Mid Latitudes
• Between T. of Cancer Arctic Circle
• Also between T. of Capricorn Antarctic circle.
  
• 4 Seasons Winter, Spring, Summer, Fall
  (exUSA)

5
LATITUDE

• Low Latitudes
• Between T. of Cancer T. of Capricorn
• Tropical, near the equator.
• 2 seasons - Wet Dry (ex Mexico, much of
  Africa) in most places

6
ELEVATION

• The higher you go, the colder it gets.
• As you go up in elevation, the air gets thinner
  and does not trap heat.
• Are there glaciers on the equator??

MOUNTAIN BARRIERS the Orographic Effect

• As winds blow across the ocean, they push
  moisture inland.
• When the moisture cloud reaches the mountains it
  gets popped by the mountain top and rains on
  the coastal side (ex California the Sierra
  Nevada Mtns.)
• By the time this cloud reaches the other side of
  the mountains, the air is dry.
• What very dry state do you find
• East of the Sierra Nevada Mts.??

PROXIMITY TO WATER

• Why is there so little difference between
  summer and winter along the coast of California?
  
• It takes the ocean a long time to heat cool!
• Wind blowing off of the water moderates
• the coastal areas.
• What is the difference between summer
• winter in Kansas?
• BIG difference in seasonswhy?
• Land heats cools quickly!!
• So The closer an area is to a large body of
  water, the smaller the difference in temperature,
  the farther away from water, the greater.

10
OCEAN CURRENTS

• The UK Europe are on the same line of latitude
  as Canada.
• Do they experience the same climate?
• A warm current called the North Atlantic Drift
  flows up from the equator and blows across the
  water and keeps Europe warmer than it should be
  at that latitude
• What about the Atacama Desert in Chile? Located
  on the coast, but one of the driest places on
  earth

11
Storms Do not necessarily affect climate, but
they do occur regularly in certain parts of the
world are associated with certain climates.
12
ATMOSPHERIC PRESSURE

• When the weather person refers to a high pressure
  system, usually it means that moisture is high in
  the atmosphere and it signifies a pattern of fair
  weather.
• A low pressure system usually brings rain.

• L Latitude
• Areas closer to the poles (arctic) receive less
  direct sunlight than areas closer to the equator
  (Tropics)
• E Elevation
• Air become less dense at higher elevations and
  cannot retain as much heat or moisture.
• The temperature decreases 3.5 degrees for every
  1000 ft. above sea level.
• M Mountain Barriers
• As airmasses cross over mtn. ranges, they lose
  their water vapor through condensation.
• Rain Shadows form on the leeward side of mtn.
  ranges.
• P Proximity to Large Bodies of Water
• Large bodies of water are slower to heat and cool
  than the air on land and this lessens extremes of
  hot or cold temperature.
• Cool winds in summer, warm winds in winter.
• O Ocean currents
• Warm currents circulate from the equator, cold
  currents from the poles.
• Cold currents cool nearby coasts, and warm
  currentsexamples S. California, Western Europe.
• S Storms
• Temporary and severe changes in weather.
• Changes follow a typical pattern in a climate
  region.
• Same types of storms get different regional name.
