Document Summary
Climate: the long term behaviour of weather in a bounded area, usually averaged over decades or centuries. Weather: the short term, fluctuating behaviour of precipitation, cloud cover, temperature and wind, usually over timescales less than a year. Latitude: proximity to water (continental vs. costal, elevation, precipitation, ocean currents. Interaction of these factors leads to different climates around the world, the diverse regional landscapes leads to a variety of climate regions. Pacific climate: marine climate influenced by pacific ocean, warm summers and cool winter, orographic precipitation- due to lifting of moist air over a mountain barrier. Seasonal variations in temperature and wetter winter season. Pacific cordillera: higher elevation (lower temperature, higher precipitation on leeward side of mountains. The prairies: the interior situation of the prairies, allows for continental climate of hot summers and cold winters, the site of polar and tropical air current convergence, so precipitation decreases from east to.
