  2. WHAT IS A CLOUD? • A collection of water droplets • Why White? -They are white, because they reflect the color of the sun. • Why Gray? – They are gray when the sun is unable to shine through.

  3. What makes clouds move? • WIND • On a windy day the clouds will move with the wind. • Speed – Clouds can move up to speeds of 30-40 mph.

  4. HOW IS FOG FORMED? • Fog is a cloud that is on the ground. • Fog is a result of warm air meeting cold air.

  5. GROUPS OF CLOUDS • There are three groups of clouds. • High Clouds - Cirrus • Medium Clouds - Alto • Low Clouds - Cumulus • Clouds that grow vertical • Stratus • Special Clouds • Fog is a special cloud.

  6. Types of High-level Clouds • There are three types of high-level clouds: • Cirrus • Cirrostratus • Cirrocumulus

  7. CIRRUS • Cirrus clouds are above 18,000 feet. • They are long and wispy. • Usually mean good weather. • What does a cirrus cloud look like?

  8. CIRROSTRATUS • Thin and sheet like. • Brings bad weather.

  9. CIRROCUMULUS • Rows of long white puffs. • Look like fish scales. • In tropical regions.

  10. Types of medium-level Clouds • There are two types of medium-level clouds: • Altostratus • Altocumulus • Medium-level clouds are between 6,500 – 18,000 feet in the air.

  11. ALTOSTRATUS • Are colored gray or blue-gray. • Covers the whole sky. • Appear before long periods of rain or snow.

  12. ALTOCUMULUS • Are puffy and gray. • Usually bring thunderstorms.

  13. Types of low-level clouds • There are three types of low-level clouds: • Stratus • Stratocumulus • Nimbostratus • Low-level clouds only go up to 6,500 feet in the air.

  14. STRATUS CLOUDS • Stratus clouds cover the whole sky. • Looks like fog in the sky. • Brings light rain. • What does a stratus cloud look like?

  15. STRATOCUMULUS • Are low, puffy, and gray. • Form in rows. • Can turn into a Nimbostratus cloud.

  16. NIMBOSTRATUS • Are dark gray. • Associated with rain and/or snow. • Produce precipitation light to moderate.

  17. Clouds that grow vertical • There are two types of clouds that grow vertical: • Cumulus • Cumulonimbus • Vertical means: (in this case) to grow upward.

  18. CUMULUS CLOUDS • Cumulus clouds are big, white, and puffy. • They grow upward. • What does a cumulus cloud look like?

  19. CUMULONIMBUS • Are anvil shaped. Winds blow the top of the cloud to make it flat. • Associated with severe weather. • The tip of the cloud points in the direction it is moving.
