Up, Up, and Away

• A lesson on clouds by
• Allison Smith and Chassity Klick

2
What are clouds?

• Clouds in some form or another are water.
  Clouds are either small water droplets or tiny
  pieces of ice particles. Meteorologists rank
  clouds according to their height and whether or
  not they are flat or puffy.

4 Types of Clouds

• Most people say that there are only three main
  types of clouds. Today will discuss those three
  types plus another. These are the types of
  clouds
• Stratus
• Cirrus
• Cumulus
• Cumulonimbus
• 
  

4
Stratus Clouds

• Uniform grayish clouds
• Cover the entire sky
• Resemble fog that hasnt yet reached the ground
• No precipitation, but at times may drizzle
• When a thick fog "lifts," the resulting clouds
  are low stratus.

5
Examples of Stratus Clouds

• Fog
• Drizzle

6
Examples of Stratus clouds

• Covers majority of sky
• Uniformly gray

7
Examples of Stratus Clouds

• Covers the entire sky
• Gray

8
Weather associated with Stratus Clouds

• Overcast day
• Steady mist or drizzle
• Stay in one place for several days.

9
Cirrus Clouds

• Thin and often wispy type clouds
• form above 18,000 feet
• fair weather
• point in the direction of air movement at their
  elevation (usually moves from west to east)
• Formed by ice needles or spicules.

10
Examples of Cirrus Clouds

• Thin and wispy
• Pointing to direction of air movement

11
Examples of Cirrus Clouds

• Fair weather
• Thin and wispy

12
Weather associated with Cirrus Clouds

• Fair to pleasant weather
• Clouds are usually white
• By watching movement of clouds you can tell which
  direction weather is approaching

13
Cumulus Clouds

• Flat bases and very puffy (like floating cotton)
• usually very isolated with large areas of blue
  sky in between the clouds.
• form below 6,000 feet and are relatively thin

14
Examples of Cumulus Clouds

• Very Puffy
• Isolated with blue sky in between

15
Examples of Cumulus Clouds

• Very puffy
• Unstable atmosphere. Causing cumulonimbus clouds
  which bring thunderstorms.

16
Weather associated with Cumulus clouds

• If clouds are low then fair weather exists
• If atmosphere is unstable enough and clouds are
  high, cumulonimbus clouds can form which brings
  rain and thunderstorms.

17
Cumulonimbus Clouds

• Thunderstorm clouds
• Massive, dark gray to black clouds
• Tremendous amounts of energy released by
  condensation of water vapor within a
  cumulonimbus.
• Cumulonimbus clouds typically form where the air
  is very unstable, especially along cold fronts.

18
Examples of Cumulonimbus Clouds

• Very black sky
• Lots of lightning
• You can see the
• energy being produced

19
Examples of Cumulonimbus Clouds

• Dark grey and black
• You can see that bad
• weather is approaching

20
Weather Associated with Cumulonimbus Clouds

• Can be seen on a warm summer day
• Can bring strong winds, hail, and rain
• Can produce lightning, thunder, flash floods and
  tornadoes.

In conclusion

• Have you ever noticed how many different types
  of clouds float in the sky? Some are white and
  lumpy while others are dark and scary and some
  look like a big gray blanket which covers the
  whole sky. Now that you know a little more about
  clouds, you can place a name with almost every
  cloud in the sky.
