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

Stability

Stabile air staysUnstable air rises Clouds will not form there is unstable air

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

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

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
