What is the difference between Climate and Weather
• Weather-day-to-day state of the atmosphere in a region
• Climate-how the atmosphere "behaves" over relatively long periods of time.
What makes up a climate?
• Events occuring in the:• Cryosphere• Atmosphere• Hydrosphere• Lithosphere• Biosphere
What are the main parts of the Atmosphere that we will look at in terms of climate and weather?
–Participation–Temperature
Latitude
Temperature- the further from the equator (north or south), the cooler it gets
Precipitation- the closer to the poles, the lower the precipitation
Why? Cooler air holds less moisture
Ocean Currents
• Temperature- if they are warm it will raise the temperature along the coast and if they are cold, they will lower the temperature.
• Precipitation- if they are warm, the climate will be wetter and if they are cold, the climate will be drier
W ind (Prevailing)
In Canada, our prevailing winds are the Westerlies, which means our weather patterns travel from west to east.
Winds
• Temperature– Off water- moderate temperature s( make it more even)– Off land- more extreme temperatures
• Precipitation– Off water- brings more moisture (makes wetter)– Off land- brings drier conditions
Elevation
• Temperature- the higher you go the colder it gets
• Precipitation- the higher you go the more precipitation you are likely to get
Relief
• Temperature- moderate on ocean side and extreme on land side
• Precipitation- side facing water(windward side) is wetter than the side facing away from the water (leeward side)
• Why?- as the air rises up the mountain it cools and since cool air • cannot hold much moisture, it releases it as it rises
Near Water
• Temperature- moderated by the ocean (especially if moving inland off the ocean) so far inland areas experience more extreme temperatures
• Precipitation- higher next to oceans, lower in areas located far inland
LOWERN Explained by Bill Nye
• Elevation- why is it colder at higher elevations? Are you not closer to the sun?
• Wind- how is wind created?
• Ocean Currents- what keeps ocean currents moving?
Arctic
CharacteristicsTemperatureCold winters, cool summers
Precipitation -low amount(less than 50 cm)
- snow
What else?High windsCoastal areas are warmer and
have heavier snow falls
West Coast
CharacteristicsTemperature
Cool summers, mild winters
Precipitation Very wet (60- 400cm precipitation)
Mountain
Characteristics Very different because of the 2 mountain ranges
TemperatureTemperatures tend to drop the higher you get in elevation
PrecipitationSummers tend to be dry, with wetter winters
Boreal
Characteristics Temperature
Temperature range is large because zone covers large area latitudinal
Precipitation Precipitation is generally low, with higher amounts in
the eastern coastal areas
Prairie
CharacteristicsTemperature
Extreme temperature range
Precipitation Generally very dry
What else?Very windy
