  • 1. What clouds are made of  Water drops  Ice crystals
  • 2. How clouds form Small drops of water turn into a gas called water vapor Once the vapor reaches a certain altitude the cold air causes the water droplets to start to stick together.
  • 3. How Clouds Are Named The height at which the cloud is located contributes to the naming. A clouds shape helps decide between the types of clouds.
  • 4. Types of clouds Type 1: High Clouds Type 2: Mid Clouds Type 3: Low Clouds Type 4: Vertically Developed Clouds
  • 5. High Clouds Cirrus Cirrocumulus Cirrostratus
  • 6. Cirrus Look like feathers. First to appear when the skies are clear. Shape and movement of the cloud indicates the strength and speed of the high altitude winds. Don’t produce rain or snow at the Earth’s surface.
  • 7. Cirrocumulus Look like cotton balls unrolled Can appear in rows or Individually Their rippling appearance helps with their identification.
  • 8. Cirrostratus Thin blanket of clouds that covers the sky.  The clouds are so thin that the moon and sun shine through. Form at about 4 miles above the ground Signals rain
  • 9. Picture of High Clouds CirrostratusCirrus Cirrocumulus
  • 10. Mid Clouds Altostratus Altocumulus
  • 11. Altostratus Consists of both water droplets and ice crystals Cover large amounts of the sky “frost” the sky. Small amounts of precipitation  Rain is possible
  • 12. Altocumulus Can be white, grey or both. Looks like bubble (foam) in a hot tub Easy to mix up with high clouds because sometimes the shading is not visible.
  • 13. Picture of Mid Clouds Altocumulus Altostratus
  • 14. Low Clouds Stratus Stratocumulus Nimbostratus
  • 15. Stratus Covers the sky like a blanket on a bed. Form horizontally Considered to be fog when low and close to the ground.
  • 16. Stratocumulus Grey clouds with dark shading Puffy and tall Do not produce rain The clouds instead form after a rain storm
  • 17. Nimbostratus Dark Grey Wet looking clouds  Related to falling rain and snow Allow no sunlight to shine through
  • 18. Picture of Low Clouds StratocumulusStratus Nimbostratus
  • 19. Vertically Developed Clouds Cumulus Cumulonimbus
  • 20. Cumulus Looks similar to cotton wool Have shapes sometimes Clumps of clouds are spaced out allowing the pretty blue sky to shine through. Looks like a rooster.
  • 21. Cumulonimbus Tall Can move into the stratosphere Contains both water droplets and ice crystals Produce different weather conditions Vertical wind can reach high speeds
