2. Adiabatic Temperatures changes
• Adiabatic is referring to any process that
occurs without heat transfer.
• This is also a concept used in many areas of
engineering and physics.

3. Orographic Lifting
• The vertical movement of air.
• Happens on the windward side of a mountain.
• Forcing the air to ascend, or move upward.

4. Frontal Wedging
• Boundary of colliding masses of cold and
warm air.
• Also a process occurs in the front that is cold
dense air.
• Warmer less dense air rises.

5. Convergence
• Lifting of air
• Results of the air in the lower atmosphere
• With they both flow together

6. Localize Convective Lifting
• Occurs when there is unequal Heating on the
Earth.
• Warms a pocket of air more then surrounding
air.
• Lowering the air density.

7. Stability ( Density Differences &
Stability and Daily Weather
• Happens when air temperature increases with
height.
• Called temperature inversion

8. Condensation
• Gas to liquid
• Warm air can hold more moisture then cold
air
• Condensation can damage a car.

9. Types of Clouds
• Cirrus clouds are high, white and thin clouds
• Cumulus consist of rounded individual cloud
masses
• They have flat bases and appearance over
domes or stadiums

10. High Clouds
• The bases are usually dark
• High Clouds are called cirrus
• High Clouds usually don’t produce
precipitation

11. Middle Clouds
• Made of ice crystals‘ and water droplets.
• Middle Clouds can go up to 2000 to 8000m

12. Low Clouds
• Stratus up to6500
• Lower clouds have puffy layers
• And they are very common around the world

13. Clouds of Vertical Development
• Consist of different cloud types.
• This occurs when warm air rises
• They also have patterns to them.

14. Fog (by cooling an evaporating)
• A collection of liquid water droplets and ice
crystals that form on the earth surface.
• A form a cloud that is very close to the
ground. http://helicopterblog.com/?p=276
15. Cold Cloud Precipitation ( Bergeron
process)
• Also known as the cold rain ice crystals
process.
• When is crystals form in higher clouds then
usual..
• Water goes from liquid to vaper

16. Warm Cloud Precipitation
• Is when air rises
• Also the warm air would go above the colder
air.

17. Rain and Snow
• Snow only occurs when it is blow frezzing
• Rain occurs when the clouds are closer to the
ground then further away.

18. Sleet, Glaze and Hail
http://honeyedhashette.blogspot.com/2011/0
• Sleet is frozen rain. 1/zuppa-toscana.html
• Glaze is a thin coding of ice.
• Hail is form of huge blocks of ice
