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.

Orographic Lifting

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

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.

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

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

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.

Condensation

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

Types of clouds

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

  ere.htm
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.



• http://eo.ucar.edu/kids/sky/cloud
  s3.htm
Middle Clouds

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

  tenv3.htm
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.



• http://www.atmos.illinois.edu/ea
  rths_atmosphere/clouds.html
Clouds of Vertical
        Development.
• Not all clouds fit in high low or
  middle clouds.
• Some clouds can form under the
  proper circumstance.

  Principles.html
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.

  azards/fog/index.html
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
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.

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.




http://zahiym5tlc.edublogs.org/
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.
