Adiabatic Temperature Changes and Expansion and Cooling
Temperature change Dry adiabatic rate Heating or cooling of saturated air Wet adiabatic rate Slow cooling by the adding of latent heat

Orographic Lifting
Land masses makes air flow over it Rainiest places are the cause of thisMost moister is lost by the time the air
reaches the other side

Convergence
Collision of different air masses to make air rise
Causes Cloud development Precipitation

Localized Convective Lifting
Unequal heating Pockets warming Particles rising called Thermals
http://www.richhoffmanclass.com/chapter4.html
Stability
Stabile air staysUnstable air rises Clouds will not form there is unstable air
http://keithrogershome.com/Chap6StabilityInstability.html
Condensation
Saturated air It forms in dew, fog, or clouds Occurs when air reaches dew point

Types of Clouds Cirrus clouds wispy, slim, and high clouds Cumulus clouds round, individual air masses middle and low
altitude Classified on the basis of formation and height
http://eo.ucar.edu/webweather/cloud3.html
High Clouds
Cirrus, cirrostratus, and cirrocumulus clouds Slim, whitish clouds Made of ice crystals Cirrus clouds are sometimes followed by a
storm

http://eo.ucar.edu/kids/sky/clouds3.htm
Middle Clouds
Altocumulus clouds 2,000 to 6,000 meters high Big dense curved clouds

Low Clouds
Stratus, stratocumulus, nimbostratus clouds Sometimes includes light precipitation Fog like layer
http://urbanext.illinois.edu/kalani/18.cfm http://www.windows2universe.org/earth/Atmosphere/clouds/stratocumulus.html
Clouds of Vertical Development
The category where that clouds don’t fit
Low elevation range Sometimes ascend up
to mid and high altitudes
http://www.free-online-private-pilot-ground-school.com/Aviation-Weather-Principles.html
Fog
Similar to a cloud A cloud with its base at or near the ground The denser the tougher to see

Cold Cloud Precipitation
Two physical processes Suppercooling- when precipitation freezes
when it touches a solid surface Supper saturated – when relative
humidity surpasses 100%

Warm Cloud Precipitation
Collision-coalescence process makes rainwater
Salt particles absorb water vapor taking it out of the air
Often big droplets form.

Rain and Snow
Rain means water that falls from a cloud Snow made of individual crystals

Sleet, Glaze and Hail
Sleet- The fall of small translucent ice partials
Glaze- Raindrops becoming supercolled as they fall through subfreezing air near the ground
Hail- Water vapor that go through a processes of freezing then pushed up making it bigger every time it goes through
