2. Adiabatic Temperature
Changing and Expansion and
Cooling.
• Temperature changes happen
even though heat is not added or
subtracted is adiabatic
temperature.
• The first type of adiabatic is dry
adiabatic, this is the cooling or
heating of unsaturated air
• The second type is wet
adiabatic, this is the cooling of
saturated air and it moves slower
than dry adiabatic.

3. Orographic Lifting
• This occurs when mountains act
as barriers to air flow, forcing the
air to ascend.

4. Frontal Wedging!!!!
• The area between warm and cold
air is a front.
• A process that occurs at a front,
dense air act like a road block.
• Less dense air rises.

5. Convergence
• The up rising of air that results
from the air in the lower
atmosphere flowing together is
Convergence
• warm days, air flows from the
ocean to the land along both
coast of Florida

6. Localized Convective
Lifting
• Unequal heating of earths
surface warms a section of air
that lowers the air density

7. Stability (Density Differnces
& Syability and DAILY
Weather
• Stable air stays in its position,
when unstable air rises.
• Temperatures Conversion
happens when air increases with
height.

8. Condensation
• The air must be fully saturated to
form any kind of condensation.
• Types of condensation is weather
dew, fog, or clouds.

9. Types of clouds
• Clouds are described by their
height and formed.
• There are different types of
clouds
• Cirrus , Cumulus and Stratus.

10. High Clouds
• High clouds are often made up of
ice crystals, they are thin and
white as well.
• They are formed by low
tempertaures, small amount of
water vapor up high.

11. Middle Clouds
• Clouds appear to 2000-
6000meters from ground.
• These Clouds put a blanket like
across the sky that looks whiteish
grey.

tenv3.htm
12. Low Clouds
• Low clouds cover a lot of the sky,
kinda like fog.
• Low Clouds form from air rising
up.
• Nimbostratus,Stratocumulus and
stratus clouds are all types of low
clouds.

13. Clouds of Vertical
Development.
• Not all clouds fit in high low or
middle clouds.
• Some clouds can form under the
proper circumstance.

14. Fog
• There is nothing different from a
fog and a cloud, the only
difference is the method and
place of formation.
• Fog is formed by radiation
cooling.
• Fog is clouds that touch to the
ground.

15. Cold Cloud
Precipitation(Bergeron
process)
• Bergeron Process is a theory
that relates the formation of
precipitation to supercooled
clouds, Freezing nuclei
• Water is supercooled when it
is below 0°C
• http://www.richhoffmanclass.
com/chapter5.html
16. Warm Cloud Precipitation
(collision-coalescence
process)
• Supersaturated is with ice is greater
than 100 percent relative humidity.
• Rain drop formation in warm clouds
is a theory called Colluision-
coalescence.

17. Rain & Snow.
• Drops of water that fall from the
sky is called rain.
• When the temperature gets really
cold the rain froze to a 6-sided ice
crystal called snowflakes.

18. Sleet, Glaze and Hail
• Clear particles that fall from the
sky is sleet.
• Glaze is when frozen rain falls to
the ground.
• Hailstorms begin as ice pallets
falling from the sky.
