This document summarizes different types of cloud formation and precipitation processes. It discusses how air is lifted through various mechanisms like frontal wedging and orographic lifting to form clouds. It also describes different cloud types like cirrus, altostratus and stratus clouds. Furthermore, it explains precipitation formation through processes like the Bergeron process and collision-coalescence as well as different types of precipitation like rain, snow, sleet and hail.

1. Clouds And
Precipitation.
By Josh Weaver.

2. Adiabatic Temperature Changes and
Expansion and Cooling.
• This is mostly when the net heat transfers to
or from the working fluid and that is zero.
• Also Adiabatic refers to any process that
occurs without heat transfer.
• This is also a concept used in many areas of
physics and engineering.

3. Orgraphic Lifting.
• Orgraohic Lifting can also be known as
upslope flow
• When Orgraphic Lifting occurs the land forces
the air to move to a higher elevation
• Forcing the air to send or move upward.

4. Frontal Wedging
• A front is the boundary between colliding
masses of warm and cold air.
• Since warm air is less dense it is wedged
upwards .
• This only happens because of a front that’s
usually raining .

5. Localized Convective Lifting
• Localized Convective Lifting happens when
unequal heating of Earth’s ground warms a
pocket of air more than the other air, lowering
the air pocket’s density.
• Also there is lot’s of different kinds of
Connective's .

6. Stability(Density Differences & Stability
and Daily Weather)
• The most stable conditions go down when air
temperature actually gets higher with height,
The name for this is temperature inversion.
• The unending circulation of the earth’s water
supply is called the hydrologic cycle.

7. Condensation
• Condensation is the process by which water vapor in the air
changed into liquid water
• Also Condensation is mostly the reasons why a lot of things
happen, Like when you glasses fog up or your cup of water
starts to sweat.
•

8. Types of Clouds
• Cirrus clouds are high, they are also white and
thin.
• There can be lots of different kinds of clouds
such as Low clouds stratus, Middle clouds
altostratus and High clouds.

9. High Clouds
• High Clouds are called Cirrus Clouds.
• Also high clouds are vary thin and wispy .
• The high clouds usually move across the sky
from west to east.

10. Middle Clouds
• Middle clouds are called altostratus clouds.
• The middle clouds are made from water
droplets
• Also the middle clouds are usually gray.
•

11. Low clouds
• Low clouds are called stratus clouds.
• Low clouds are usually gray looking
• Also low clouds usually form with warm
fronts.

12. Clouds of Vertical Development
• Clouds are usually classified into a system that
uses Latin words to tell the looks of different
clouds.
• They have lots of different words for clouds
but they usually gave meaning to them.

13. Fog (by cooling and by evaporation)
• Fog is pretty much the same thing as a cloud.
• But the only difference is that Fog have a base
that stays vary close to the ground.
• Fog also deals with a lot of precipitation.

14. Cold Cloud Precipitation (Bergeron
Process)
• This process relates to the forming of
precipitation.
• Also the Bergeron Process is in order for water
droplets to work

15. Warm Cloud Precipitation(collision-
coalescence process)
• The main thing that has to do with all the
clouds is precipitation.
• Also the collision-coalescence all about
raindrop formation in warm clouds.

16. Rain and Snow
• Rain and snow are the same thing as
precipitation.
• There are lots of different types of
precipitation and rain and snow are just a
couple.

17. Sleet, Glaze and Hail
• Sleet, Glaze and Hail are mostly freezing rain.
• Most of Sleet and Hail happens when
precipitation falls from the sky or clouds. In
liquid raindrops and as it gets lower it freezes
creating Hail or Sleet what ever you want to
call it.
