Cloud Formation and Adiabatic Processes |

1. Cloud Formation

2. Bell-work • Two ways to saturate air: • __________________ • __________________ 2. As air rises, it cools rate of _____°C / km 3. As ascending air rises, it __________ and __________

3. Adiabatic Temperature Changes

4. Dry and Wet Adiabatic Rates 5°C wet 10°C dry

5. Latent Heat of Condensation The600 calories of heat energy is released into the surrounding air by gas molecules then they condense into a water. Warms the air!

6. Cloud Formation • A parcel of air _______ • It cools to its _____ ________ • The water vapor ____________ into water droplets. • The air reaches ______________ • ___________ form.

7. Cloud formation

8. At what altitude does the air temperature cool to be the same as the dew point temperature? At that altitude and temperature, will the clouds be liquid or ice crystals?

9. Dry air

11. Death Valley Rain Shadow Desert

12. 4 processes of cloud formationpg. 114- 1. Orographic lifting 2. Frontal Wedging 3. Convergence 4. Local Convection

13. White board • Name • Diagram • Location • Type of cloud (puffy cumulous, towering thunderstorm, or low stratus) • Type of rain (sudden quick rain shower, constant rain, no rain)

14. 1. Orographic Lifting Processes

15. Wetter Windward Locations and Leeward Rain Shadows

16. Heavy Precipitation in Mountains Snow Pack in the Rocky Mountains

17. 2. Frontal Wedging:a warm front with humid air rises over a cold front.As it rises, its cools and condenses into clouds

18. Frontal wedging clouds Cold air fronts collide with warm air Large areas of clouds and steady precipitation form all along the front

19. 3. Convergence

20. Clouds Converge over Southern Florida

21. 4. Localized Convection

22. Bell Work: Match the Location with the Type of Cloud Formationorographic lifting, convergence, frontal wedging, local convection

23. Global precipitation Is there a relationship between cloud formation and precipitation??
