1 What is Climate? An areas long term pattern of weather An areas long term pattern of weather What factors would be needed to describe an areas climate? What factors would be needed to describe an areas climate?

2 The 2 main factors that contribute to climate are Temperature Temperature Precipitation Precipitation The 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 Description Climate Control Description Latitude Latitude Elevation Elevation Nearby Water Nearby Water Ocean Currents Ocean Currents Topography Topography Prevailing Winds Prevailing Winds Vegetation Vegetation 0º to 90º on globe Amount above sea level Near oceans or lakes Cold or warm currents Near 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 Affects all areas Temperature Temperature The farther from the equator the cooler the temperature The farther from the equator the cooler the temperature Precipitation Precipitation Areas at HIGH PRESSURE (30º and 90º) are drier Areas at HIGH PRESSURE (30º and 90º) are drier Areas at LOW PRESSURE (Oº and 60º) have more precipitaton Areas at LOW PRESSURE (Oº and 60º) have more precipitaton

5 Elevation Effects mountains the most Effects mountains the most Temperature Temperature The higher the elevation the cooler it is The higher the elevation the cooler it is Precipitation Precipitation The higher the elevation the drier it is The higher the elevation the drier it is

6 Nearby Water Effects areas near large water masses (oceans or large lakes) Effects areas near large water masses (oceans or large lakes) Temperature Temperature Water does not change temperature as much as land Water does not change temperature as much as land Less of a temperature range = milder climates Less of a temperature range = milder climates Precipitation Precipitation Rainfall is usually higher if the area is downwind Rainfall is usually higher if the area is downwind

7 Ocean Currents Effects areas near the ocean Effects areas near the ocean Temperature Temperature Warm Currents warm areas Warm Currents warm areas Cold currents cool areas Cold currents cool areas Precipitation Precipitation Areas near warm ocean currents may be prone to tropical storms Areas near warm ocean currents may be prone to tropical storms

8 Topography Effects areas near mountains Effects areas near mountains Windward Leeward Temperature: Cooler Precipitation: More Temperature: Warmer Precipitation: Less

9 Prevailing Winds Effects Mainly the Mid Latitudes Effects Mainly the Mid Latitudes Temperature Temperature It depends where the air is coming from It depends where the air is coming from If it is coming from a cold region the area will be colder If it is coming from a cold region the area will be colder Precipitation Precipitation It depends where the air is coming from It depends where the air is coming from If it is coming from the ocean the area will have more precipitation If it is coming from the ocean the area will have more precipitation
