3. How Is Climate Different from Weather? Weather - the conditions outside on a particular day, can be determined by looking outside Climate - the usual pattern of weather in a region over a long period of time. To determine the climate in a region, you would need to study the weather for about 30 years.

4. Describing Weather Meteorologists – scientists who study weather provide information about:  temperature  precipitation  wind speed  relative humidity (amount water vapour in air)  atmospheric pressure (force exerted by weight of air above)  cloud cover  today’s weather?  Current Weather - The Weather Network Current Weather - The Weather Network

5. 1.Climate Zones – uses temp., percip., and plants to identify climate zones Classifying Climate

6. Newer system of classifying climate based on:  landforms, soil, plants and animals  climate  human factors (cities, farming practices…) 2. Ecoregions

7.  series of graphs that show temperature and moisture conditions in a region  only describe climate  can make climate projections into future  Canadian Climate Impacts and Scenarios Canadian Climate Impacts and Scenarios 3. Bioclimate Profiles

8.  The following factors determine the climate for a location: LOWER Near Water Latitude:  as you move away from the equator, the sun’s rays are less direct. Therefore, the temperature decreases. Ocean Currents:  The temperature of the ocean current affects the air that passes over it. Winds:  The prevailing winds are the established pattern of winds. These winds move the air masses that effect our weather. 4. Climate Factors

9. Elevation:  It gets colder as the elevation increases. As air moves up, is expands because air pressure is less. As expands, it loses heat. 1 o C/100m Relief:  Windward side of a mountain range is warm and wet. The leeward side of a mountain range is warm and dry. Near Water:  Water has a moderating effect on temperature. In the summer, it keeps the air over it and nearby cooler. In the winter, it causes the temperatures to be warmer.
