2. Adiabatic temperature changes
• When air expands it drops
• Change in temp without addition
or removal of heat

3. Orographic lifting
• This occurs when air mass is
forced from low elevation to a
higher elevation.
• This happens high up in the sky.

4. Frontal wedging
• When cold and warm air collide
on the surface of the earth.
• Warm air is force up because its
less dense.

5. convergence
• Greater in flow then out
flow.

6. Localized convective lifting
•Warm air rising above
an particular local city.

7. stability
•The balance of the
weather

8. condensation
• When water vapor cools to its
dew point and changes back in
to a liquid.

9. Types of clouds
• There are four types of clouds.
• Cumulus, Stratus, cirrus, and
Cumulonimbus.

10. High clouds
•Made out of air that is
so cold its made up of
ice crystals.

11. Middle clouds
• Made up of ice crystals.
• In the middle part of the
atmosphere.

12. Low clouds
•Located in the lower
part of the atmosphere.
•Called stratus.

13. Clouds of vertical development
• Crated from the bottom up.
• Called cumulus.

14. fog
•Crated by water vapor in
the air.

15. Cold cloud precipitation
• Known as snow or sleet.
• Happens when it rains and
its below 32 degrees.

16. Warm cloud precipitation
• Known as rain
• Happens when it rains and its
above 32 degrees.

17. Rain and snow
• Rain changes to snow when the
temp goes below 32 degrees.

18. Sleet, glaze and hail
• Sleet is a very wet form of snow.
• Hail is frozen rain.
