Troposphere |
Lowest layer of the Earth's atmosphere. WHERE weather happens |
|
|
Atmospheric pressure |
Pressure exerted by the weight of the air in the atmosphere. |
|
|
High pressure |
Have more atmospheric Mass above their location. |
|
|
Low pressure |
Have less atmospheric Mass above their location. |
|
|
Pressure gradient Force |
Cause the wind gradient between high and low pressure areas to move. |
|
|
Coriolis effect |
Deflection of wind away from a straight path because the Earth's rotation affects air currents and ocean currents. Greater effect at higher latitudes and no effect at the equator. |
|
|
General model of atmospheric circulation |
Predict position of:
Dominant air pressure system
And
Prevailing wind directions.
Based on:
Seasonal changes of insolation
Physical consequences of rotating sphere |
|
|
Equatorial low pressure |
Equator belt I T C Z |
|
|
Latitude |
What is the primary control of temperature distribution? Because of earth sun geometry |
|
|
Controls on global temperature patterns |
Altitude, land and water heating differences, ocean currents and sea surface temps, and cloud cover. |
|
|
Continental climate |
Dryer land, so more extreme temperature variations |
|
|
Marine |
Climates are moderated |
