  1. Clouds Hear a Music Clip

  2. Cloud Classification 1.Based on Altitude Appearance from the ground

  3. High Level Clouds • Base of the Cloud is above 6000 m (over 20,000 feet) • - very cold - Thin and white in appearance - Composed of ice crystals

  4. Cirrus • WEATHER: • Usually associated with fair weather • Sometimes in advance of a storm system - Wispy or feathery in appearance - Called “Mares’ Tails”

  5. Cirro-Stratus • WEATHER: • Precipitation will follow - White-veined clouds that produce “halos” around sun or moon (due to light waves being bent by ice crystals)

  6. Cirrocumulus • Least common of high clouds - Appear like rippled sand or waves or fish scales http://aposf02.cityu.edu.hk/~ksliu/obs/cloud/Cirrocumulus1.jpg - “Mackeral Sky” • WEATHER: • Omen of good weather

  7. Mid Level Clouds • Bases appear between 2,000 & 6,000 m. • (10,000 – 20,000 feet) - Composed mainly of water droplets

  8. WEATHER: • consider fair weather, they often follow storms Alto-Cumulus - White to gray / larger than cirrocumulus • Puffy / often rippled or appear in waves - “Sheep-back” clouds

  9. Alto-stratus - Formless gray or bluish in color • Forms a thin veil over Sun or moon http://www.mmem.spschools.org/grade5science/weather/altostratus.jpeg WEATHER: - light precipitation is coming

  10. Low Level Clouds - Base below 2,000 m (under 10,000 feet) - Composed usually of water droplets unless the temperatures are very cold

  11. Cumulus - Dense, billowy clouds - Flat bases, developing vertically - Can be isolated or closely packed WEATHER: - Fair weather / lasts for a relatively short period of time then disappear

  12. Strato-Cumulus - Puffy, Soft, gray clouds - Rolling mass of thin lumpy clouds / often joined together / might appear in rows WEATHER: - Some precipitation with breaks of clear sky in between - Not long lasting

  13. Stratus - overcasted, Uniform cloud resembling fog • WEATHER: • rain or drizzle • Lift quickly and indicate a fine day ahead - low layer that covers entire sky

  14. Nimbo-stratus - Dark gray sheets that blot out the sum • WEATHER: • Indicative of lengthy precipitation • Light to moderate precipitation in the form of rain or snow depending on the temperature

  15. Other Clouds Contrails– High level / extremely cold temperatures formed from Jet engines Billows – unstable air flows

  16. Mammatus Clouds – examples of sinking air - harmless, but often seen after thunderstorms have passed. Pileus – smooth clouds capping over mountain tops

  17. OROGRAPHIC CLOUD clouds that develop in response to the forced lifting of air by the earth's topography

  18. Vertically Developed Clouds - Arise usually from swelling Cumulus - Grow to heights of over 39,000 feet by thermal convection of frontal lifting - Incredible amounts of energy

  19. Cumulo-nimbus • Towering Cloud - Often with “anvil head” • WEATHER: • Fast building / Squall line • - Heavy rainfall, thunder, lightning, hail & tornadoes
