How Is Climate Different from Weather?
Weather - the conditions outside on a particular
day, can be determined by looking
outside Climate - the usual pattern of
weather in a region over a long period of time.
To determine the climate in a region, you would
need to study the weather for about 30 years.

Describing Weather
  • Meteorologists scientists who study weather
    provide information about
  • temperature
  • precipitation
  • wind speed
  • relative humidity (amount water vapour in air)
  • atmospheric pressure (force exerted by weight of
    air above)
  • cloud cover
  • todays weather?
  • Current Weather - The Weather Network

4
Classifying Climate
  1. Climate Zones uses temp., percip., and plants
    to identify climate zones

5
2. Ecoregions
  • Newer system of classifying climate based on
  • landforms, soil, plants and animals
  • climate
  • human factors (cities, farming practices)

6
3. Bioclimate Profiles
  • series of graphs that show temperature and
    moisture conditions in a region
  • only describe climate
  • can make climate projections into future
  • Canadian Climate Impacts and Scenarios

4. Climate Factors
  • The following factors determine the climate for a
    location
  • LOWER Near Water
  • Latitude
  • as you move away from the equator, the suns rays
    are less direct. Therefore, the temperature
    decreases.
  • Ocean Currents
  • The temperature of the ocean current affects the
    air that passes over it.
  • Winds
  • The prevailing winds are the established pattern
    of winds. These winds move the air masses that
    effect our weather.

8
  • Elevation
  • It gets colder as the elevation increases. As
    air moves up, is expands because air pressure is
    less. As expands, it loses heat. 1oC/100m
  • Relief
  • Windward side of a mountain range is warm and
    wet. The leeward side of a mountain range is
    warm and dry.
  • Near Water
  • Water has a moderating effect on temperature. In
    the summer, it keeps the air over it and nearby
    cooler. In the winter, it causes the
    temperatures to be warmer.
