6 Six Factors Affecting Climate 1. Latitude2. Altitude3. Distance from the Sea4. Wind Direction5. Ocean Currents6. Precipitation
7 LatitudeLines extending east and west around the earth and measure the distance north and south of the Equator (0 degrees)
8 Latitudebecause the Earth is tilted on its axis, the sun heats it unevenlyAreas closest to the equator (tropical and subtropical zones) get more direct sunlight all yearAreas farther from the equator (temperate and polar zones) get less direct sunlightthe number of hours of sunlight per day changes a great deal throughout the year
10 Altitude The higher the altitude, the colder the temperature 150m rise in altitude = 1 degree drop in temperature
11 the surface of land heats and cools more quickly than water Distance from the Seathe surface of land heats and cools more quickly than water
12 Distance from the SeaThe surface of land heats and cools more quickly then the surface of waterlarge landmasses can vary between temperature extremesSummer and winter temperatures on the West Coast are moderated by the water
13 Wind DirectionDepending on their point of origin, winds can warm or cool the temperature
14 Wind DirectionIn Canada, prevailing winds (those that usually come from one direction) most often come from the west, or from the northWest Coast communities are unique in Canada with winter temperatures above freezing. They have the mildest winter temperatures as a result of warm westerly winds coming off the ocean.
15 affect temperature by warming or cooling the air Ocean Currentsaffect temperature by warming or cooling the air
16 Ocean CurrentsOcean currents are either warm or cold, depending on their originAffect temperature of land by warming or heating the air blowing over themWarm air can hold more water than cold air; this is why West Coast has a mild, wet climate
17 Precipitation= drizzle, showers, heavy rain, hail, snow, or fog - all have an impact on the location they fall
18 Precipitationthe amount of precipitation a location receives depends on its distance from the sea and the prevailing windsWestern Canada experiences three types: orographic, convection, and frontal
19 Frontal - rain attached to a cold front, which is a weather system that can produce large amounts of rain and strong winds. The most common kind of rain.Orographic - caused when masses of air pushed by wind are forced up the side of elevated land formations, such as large mountainsConvection - Caused by the heat of the sun. Most likely to occur on a hot and humid day. Can produce large amounts of rainfall in very short periods of time.
