WEATHER
|
Day-to-day change in atmospheric conditions at a particular place.
|
|
|
CLIMATE
|
Average long term weather conditions in a region.
|
|
|
Weather & Climate are influenced by...
|
Global air patterns & ocean currents.
|
|
|
All weather & climate ultimately arise from...
|
the uneven heating of the Earth.
•Sun's rays fall more directly at the equator than at the North & South poles. •The uneven heating causes GLOBAL WIND CIRCULATION PATTERNS: -warm air at the equator rises towards the poles, creating an area of low pressure. -cold air from the poles sink towards the equator, creating an area of high pressure. -The result is a pattern of prevailing winds in both Northern & Southern Hemispheres. |
|
|
Ocean Currents are caused by...
|
The wind & by variations in the density of water.
Ocean currents help transfer heat from the equator regions to the poles. |
|
|
Daily weather patterns are caused by movements of...
|
AIR MASSES: Large bodies of air with similar temperature, humidity, & pressure.
Boundary between 2 air masses is called a FRONT. A COLD FRONT occurs when a cold air mass overtakes & displaces a warm air mass. A WARM FRONT occurs when a warm air mass rises over a cold air mass. An OCCLUDED FRONT occurs when a cold front catches up with a warm front & the 2 weather systems merge. Cloud & Precipitation are characteristics of fronts. |

|
Study of short term weather patterns & data of particular areas.
