1 What is Climate? An area’s long term pattern of weather What factors would be needed to describe an area’s climate?
2 The 2 main factors that contribute to climate are TemperaturePrecipitationThe average temperature is not enough. Highs and Lows are necessary to see the temperature range.The amount of rain and time of year rain falls.
3 Many factors can affect temperature and precipitation Climate Control DescriptionLatitudeElevationNearby WaterOcean CurrentsTopographyPrevailing WindsVegetation0º to 90º on globeAmount above sea levelNear oceans or lakesCold or warm currentsNear Mountain Ranges (Windward and Leeward)Global winds. (What kind of air are they bringing?)How many plants grow in an area
4 Latitude Affects all areas Temperature Precipitation The farther from the equator the cooler the temperaturePrecipitationAreas at HIGH PRESSURE (30º and 90º) are drierAreas at LOW PRESSURE (Oº and 60º) have more precipitaton
5 Elevation Effects mountains the most Temperature Precipitation The higher the elevation the cooler it isPrecipitationThe higher the elevation the drier it is
6 Nearby WaterEffects areas near large water masses (oceans or large lakes)TemperatureWater does not change temperature as much as landLess of a temperature range = milder climatesPrecipitationRainfall is usually higher if the area is downwind
7 Ocean Currents Effects areas near the ocean Temperature Precipitation Warm Currents warm areasCold currents cool areasPrecipitationAreas near warm ocean currents may be prone to tropical storms
8 Topography Effects areas near mountains Leeward Windward Temperature: CoolerPrecipitation: MoreTemperature: WarmerPrecipitation: Less
9 Prevailing Winds Effects Mainly the Mid Latitudes Temperature It depends where the air is coming fromIf it is coming from a cold region the area will be colderPrecipitationIf it is coming from the ocean the area will have more precipitation
