This document discusses various types of clouds and precipitation. It describes cloud formation processes like orographic lifting, fronts, convergence, and localized lifting. It explains cloud types like cirrus, cumulus, and stratus clouds. The document also covers precipitation formation theories like Bergeron process and collision coalescence. Finally, it defines different types of precipitation including rain, snow, sleet, glaze, and hail.

Orogrophic Lifting
• An easier way to explain this would be
the windward and leeward side of
mountain. One side gets all the
precipitation, and the other side gets
nothing.

3. Fronts
• A boundary between colliding masses
of warm and cold air.
• Less dense air rises

4. Convergence
• When air rises because the air under it
flows together

5. Localized Lifting
• When un-equal heating warms up one
pocket of air more than the others ,
making that air less dense

6. Stableness
• Air that sits still
• Stable air stays in one place while
unstable air rises and moves around

Condensation
• For condensation to happen, there
needs to a surface
• The air needs to be saturated
• When this happens in he air we call
clouds

Cloud types and Precipitation
• Cirrus- high up, white, and are thin.
Look like wispy feathery cloudy
• Cumulus- big fluffy clouds that have a
flat bottom
• Stratus- cover much and often most of
the sky. No distinctive individual clouds

9. Fog
• A cloud that is so heavy it fell to the
ground

10. Precipitation
• For precipitation to form, the water
vapor in the air must get bigger by one
million times

Bergeron Process
• Theory that describes the precipitation
of cold clouds
• Water below 0C is said to be super
cooled
• Water in this stage will automatically
freeze with contact

12. Collision Coalescence
• When air is super saturated with ice
• Theory that describes the formation of
raindrops

13. High Clouds
• Bases reside between 16000 and 45000
feet
• Because of the altitude they are
mainly composed of ice crystals
• Clouds in the region would be cirrus,
cirrocumulus, and cirrostratus

14. Middle Clouds
• Bases found at 6,500 to 23,000 feet
• Main clouds here are altostratus, alto
nimbus, and nimbostratus clouds
• Their height depends on the region
they form

15. Low Clouds

16. Rain and Snow
• Forms when water droplets in clouds
size up one million times
• Depending on the weather in the
region, the water droplets may freeze
into crystals and become snow
