Ch 17 Section 3 Climate
2
Climate Climate means the long-term average of weather conditions—wind, temperature, precipitation, moisture, and other aspects of weather.
3
Biogeophysical system
Biosphere- everything organic, including plants, animals and humans Hydrophere- is liquid water in oceans, lakes, rivers, soil and underground Cryosphere- is frozen water in snow, ice, and glaciers Lithosphere- solid earth including soil, rocks and mantle.
4
Cause of Climate Latitude is the primary factor that determines climate at a given location. The angle of sunlight at the different latitudes is why climate is different.
5
Ocean and Land Influence
Continental Climates- Temperature can vary greatly Maritime Climate- Temperature varies little. Summers are cooler Winters are warmer Difference in locations can have a big effect on the climate even at the same latitude.
6
At the same latitudes you can have a very big forest or a desert.
7
Precipitation Humid climates are associated with low-pressure areas in the tropics and middle latitudes. Rainfall is greater near the equator because of the trade winds. Arid climates are associated with high pressure areas.
9
Influence of Mountains
Mountains block weather systems Cause lee rain shadow Why on the other side of mountains it is much dryer.
10
Influence of Water A sea breeze blows from the water toward the land in the afternoon, when the land is warmer than the water. Warm air rises over land; allowing cool air form the sea to move toward the land. Reverse happens at night
