1Factors that Affect Climate Note PageCreated by Nancy Robbins, Sunnyside
2Altitude The height of land above sea level Temperature drops as you go higherElevationAt higher elevations, air is thinner so it holds less heat
3LatitudeThe distance north or south of the Equator, lines known as a “parallel”Amount of direct sunlight an area receives affects temperatureSun shines directly on equator so itis warmer, less direct sunlight at the poles so it is colder.Earth is tilted on its axis, so northern and southern hemispheres receive more direct sunlight in summer season, less in winter season.
4Topography Surface features Humid air from the ocean rises and cools – forms clouds and precipitationMountain sides facing away from oceans are typically very dry and air is warm* Rain Shadow-land down wind from mountains
5Oceans & Lakes Keeps weather from becoming to extreme – moderate Water temperatures change slower than land temperaturesWinds from oceans/lakes affect land temperature – cool ocean current = cool winds; warm ocean currents = warm winds
6Earth’s Winds Push warm and cold air masses Six belts – push moisture clouds, air pollution moistureDoldrums – ‘trade winds’ meet near equator, warm moist air, forms lots of clouds
