1) When air rises it cools through adiabatic expansion and condenses water vapor to form clouds like cirrus, cumulus, and stratus at different heights. 2) Orographic lifting occurs when air is forced to higher elevations over rising terrain, cooling and potentially causing precipitation. 3) Convergence draws in surrounding air which rises then sinks, heating and cooling in localized areas and potentially causing convection storms.

When air is allowed to expand, it cools, and when
it is compressed, it warm
 When the temperature changes without adding
hot of cold air it is called adiabatic temperature
changes
 When the air is unsaturated and the air warms
up it is called dry adiabatic
 When the has water vapor in it the adiabatic rate
is slower then dry adiabatic rate

3. Orographic lifting is when an air mass is
forced from a low elevation to a higher
elevation as it moves over rising terrain.
 It is when air is forced to go with the
terrain

4. Front
 A front is a boundary between a cooling body
mass of hot air and cold air. A frontal wedging is
ware the cold air is in the front

5.  Convergence is the natural heating and
culling of the surface. Hot air rises cold air
sinks
 Hot air rises because it is less dens
 Cold air sinks because it is more dens

6.  Localized convection is when hot air rises in a
pocket of les dens air and snicks as more dens
cold air

7. Stable air stays in its original position, wile
unstable air rises
 the most stable conditions for the air is when
air temperature actually increases with
height it Is called a temperature inversion.

8. For condensation to happen the air must be
saturated to make dew, fog, or clouds
 When air is saturated the water vapor
condensates on to dust witch is called
condensation nucli.

9. Clouds are classified on the basis of there form and
height.
 Cirrus clouds are high White and thin. They can
happen as patches or look like fluffy blankets in
the sky.
 Cumulus clouds are single round cloud masses
with a flat base and a appearance that seams
like it is rising.
 Stratus clouds are the clouds that cover the sky
completely with small or no brakes in it. With no

individual cloud in it

10.  The high clouds are called cirrocumulus cloud
and there are three clouds that make up the
high cloud they are the cirrus, cirrocumulus,
and cirrostratus clouds.
 It is 6000m in the air
 All high clouds are thin and white and often
made of ice crystals
 http://eo.ucar.edu/kids/sky/clouds3.htm

11.  The middle clouds also known as the
altocumulus cloud they can change there form in
different conditions
 They are 2000, 6000 meters in the air
 They can be a Wight or gray with an infrequent
light snow or drizzle mar accompany the clouds
http://www.bigbranch.net/middle%20clouds.htm

12.  There is three types of low clouds stratus,
stratocumulus, and nimbostratus.
 The stratus cloud is a fog like layer that always cover
the sky. When the cloud gets uneven it becomes an a
stratocumulus cloud
 A nimbostratus cloud is the clouds that produce
precipitation

13.  Clouds that don’t fit in the three height
categories
 The clouds with vertical development are
filed with unstable air and all of them are
related to another.
 They can also produce rain

14.  It starts when the earth cools off rapidly bye
radiation

15.  When the temperature is 4c snowflakes
usually melt and continuo as rain drops
 When the temperature is -5c ice crystals join
into larger clumps and form a snow flake.

16.  Sleet is the fall of small particles of clear
transparent ice.
 Glaze also known as freezing rain it happens
when rain becomes 0c and when it hits a
surface I turns into ice.
 Hail is produced in a cumulonimbus cloud it
starts as a small ice pellets that grow by
collecting super cooling water as they fall.
