2. Adiabatic Temperature Changes And
Expansion And Cooling
• The temperature will change even if the heat
is not added or going away
• Wet adiabatic is slower than dry adiabatic
• The cooling and heating is unsaturated air
which is called dry adiabatic rate.

3. Orographic Lifting
• This is the first mechanisms that causes the air
to rise
• The mountains will act as barriers for the air
to flow
• The force will cause the air to go up.

4. Frontal Wedging
• This is the second mechanism that causes the
air to rise
• The front is where the warm and cool air can
go
• Warmer air will rise

5. Convergence
• This is the 3rd mechanism
• This is air that is lifting
• The air in the lower atmosphere coming
together

6. Localized Convective Lifting
• This is the 4th mechanism
• Unequal air heats up more than the air that is
being surrounded
• The air only gets a portion of it

7. Stability(Density Differences &
Stability and Daily Weather)
• Stable air stays where it is at
• None stable air sometimes rise
• When the air is most stable is when the air
temperature rises with the height

8. Condensation
• When there is dew, clouds, or fog the air has
to be saturated
• This happens in the air above the ground
• There must be a surface for water-vapor
condensation

9. Types Of Clouds
• The Cirrus cloud is high in the sky, has a white
color and the cloud is thin. The clouds will
appear to feel very soft.
• The Cumulus cloud are round and the base is
flat.
• The Stratus cloud covers the whole sky or
sometimes will cover most of the sky.

10. High Clouds
• There are 3 different types of clouds.
• They are Cirrus, Cirrostratus, Cirrocumulus.
• They are the same because they all have
crystals, their color is white, and the cloud is
thin.

11. Middle Clouds
• Middles clouds have a whitish or grayish color
to them.
• There are only two different clouds.
• There called’ Middle clouds’ because they are
2000-6000 meters apart.

12. Low Clouds
• There are 3 different kinds of clouds
• They are Stratus, Stratocumulus, and
Nimbostratus.
• Nimbostratus is the cloud that’s the main one
that makes rain.

low.htm
13. Clouds of Vertical Development
• Some of the clouds don’t even have the height
that they mentioned.
• All of the clouds are related and have the
same unstable air.
• Cumulonimbus clouds would make rain or
thunderstorms.
http://en.wikipedia.org/wiki/Cloud
14. Fog( By Cooling And By Evaporation)
• Fog and clouds are the same.
• When there is moist air it will become fog.
• When the warm air moves over warm water it
will evaporate.

15. Cold Cloud Precipitation (Bergeron
Process)
• Water that is liquid states below 0 degrees is
called’ super cooled’.
• The super cooled water will freeze when it
touches a solid.
• There are different levels of ice and liquid.

16. Warm Cloud Precipitation( Collision-
Coalescence Process)
• When air is saturated to water, it is called ‘
supersaturated’.
• Warm clouds come together with large cloud
droplets.
• Then the cloud droplets come together with
smaller droplets and form raindrops.

17. Rain and Snow
• When the surface temperature is 4 degrees
Celsius then snowflakes will melt.
• Then the snow turns into rain before it hits
the ground
• Six sided ice crystals will form when there is
low temperature

18. Sleet, Glaze, and Hail
• Glaze is also freezing rain
• Sleet is transparent ice
• Hail will be produce in the Cumulonimbus
clouds
