  1. Cloud Types 18.3 Brain Pop: Clouds

  2. 18.3 Types of Clouds • Clouds are classified based on how they formed and their height • 3 basic forms…

  3. Cirrus: (= a curl of hair) • Thin, white, wispy, feathery • Made from ice crystals at high altitudes • Seen in fair weather, but can mean • rain or snow is coming

  4. Cumulus: (= a pile) • Rounded, thick, • puffy masses • Formed by vertically rising air currents • Usually mean fair weather

  5. Stratus: (= a layer) • Layered, gray, and smooth • Form in sheets at low altitudes • Block out sunlight - associated with rain

  6. 3 levels of height  can have seasonal and latitudinal variation

  7. cirrocumulus Cirrus • High Clouds: (above 6000 meters) Cirrostratus halo around the sun cirrostratus

  8. altocumulus • Middle Clouds: (2000-6000 meters) altostratus

  9. stratocumulus Stratus • Low Clouds: (below 2000 meters) • nimbostratus

  10. cumulonimbus • Clouds of vertical development: • (start at 2000 meters – mid/high)

  11. Fog: A cloud with its base at or very near the ground • The only difference between clouds and fog is their method and place of formation.

  12. Fogs caused by cooling • Fog forms when warm oceanic air moves over a cold water current, then wind blows it over land Ex: coastal California

  13. OR fog forms over land as air temperature near the ground drops overnight and reaches the dew point in the early morning

  14. Fogs caused by evaporation • Fog forms over water when water temperatures are still warm, but air temperatures have fallen rapidly • Fall and early winter
