The average weather conditions in an area over a long period of time
Day to day conditions measured by precipitation, temperature, cloud cover, wind speed and humidity
Forms of precipitation
rain, snow, sleet, hail
the difference in elevation between the highest and lowest parts of an area
most extreme form of relief
Why does it get colder with increasing altitude
Due to lower pressure & higher altitudes
a relatively dry climate with very hot summers and very cold winters, characteristic of the central parts of Asia and North America.
A climate moderated by proximity to oceans or large seas. It is usually cool, cloudy, and wet and lacks the temperature extremes of continental climates.
Moderate rainfall, temperatures that rarely fall below freezing.
Difference between the highest and the lowest temperature
Any form of water that falls from clouds and reaches Earth's surface.
2 major ocean currents off of Canada's coast
Labrador current off the east - cold
North pacific current off the west - warm
a body of air that has about the same temperature and moisture throughout
air mass over an ocean vs over land
the temperature of the ocean will affect the temperature of the air above it and there is always a breeze closer to water
Air expands and cools as it rises The pressure of the air molecules changes as you move upward from sea level into the atmosphere.
the horizontal movement of air caused by differences in air pressure
prevailing winds in Canada
western (west to east)
polar front jet stream
when the dry cold air meets up with wet tropical air
What does a climograph measure?
temperature and precipitation
even vs seasonal precipitation
even- when the precipitation is roughly even throughout the year
seasonal- the amount of precipitation varies depending on the season
