6-4.3 • Classify shapes and types of clouds according to elevation and their associated weather conditions and patterns.
1. What are clouds? • Clouds are of billions of water droplets. 1,000,000,000
2. How do clouds form? • Clouds form from the condensation of water vapor. • Water warmed by the sun rises (evaporation), cools, & changes to water droplets (condensation).
3. How are clouds classified? • A. By shape • B. By altitude • C. By precipitation
1. Cumulus (meaning "heap” / “piled up” 2. Medium or low elevations. 3. Large, fluffy & puffy with flat bases. 4. White = fair weather ■ 5. Darker = rain or thunderstorms. A. Cumulus Clouds
1. Cirrus (meaning "curl of hair”) 2. High elevations. 3. Wispy, made of ice crystals. 4. Signals fair weather or the approach of a warm front. B. Cirrus Clouds
1. Stratus (meaning “layered”) 2. Forms at medium or low elevations. 3. Spread out layer upon layer covering a large area. 4. As clouds thicken, precipitation may occur C. Stratus Clouds
Review: The 3 cloud shapes Cumulus (Puffy) Cirrus (Wispy) Stratus (Layered)
5. What are the 3 high altitude clouds? A. Cirrus B. Cirrostratus C. Cirrocumulus High Altitude Clouds
6. What are the 2 mid-level clouds? B. Altocumulus A. Altostratus Mid-level Clouds
7. What are the 3 low level clouds? B. Cumulus (vertical cloud) A. Stratus Low-level Clouds C. Stratocumulus
8. Prefixes / Sufixes • The prefix cirro- describes high clouds. • The prefix alto- describes middle elevation clouds • The prefix/sufix nimbus- refers to rain.
9. Name 2 storm clouds. A.Nimbostratus B. Cumulonimbus (a thunderhead; may accompany a cold front) Low-level Clouds
10. Fog • Clouds that form when condensation occurs at or near the ground are called fog.
