Clouds and Weather
Lets start off with Clouds @ BrainPop

Stratus Clouds:Flat layered clouds that spread like a blanket
across the sky.
Cumulus Clouds:White, puffy clouds that appear to rise from flat
bases.
Cirrus Clouds:Look like wispy streaks or feathers.
Cumulus CloudsCumulus clouds are puffy white or light gray clouds that look like floating cotton balls. They have sharp outlines and a flat base.Image courtesy of Carlye Calvin
Cumulus CloudsOccasionally Cumulus clouds show vertical development and produce tower-like extensions. These Cumulus clouds are in the early stages of development. Image courtesy of the UCAR Digital Image Library
Cumulus CloudsThis image of cumulus clouds was taken in in the mountains of Colorado. You can tell this was taken in the mountains because some of the clouds appear to be below the person taking the photograph!Image courtesy of Olga and Sergei Kuznetsov

Stratus CloudsThis image of stratus clouds was taken in San Giamano, Tuscany, Italy. The stratus cloud appears as fog on the ground.Image courtesy of Sara Martin

Cirrus CloudsCirrus clouds are composed entirely of ice and consist of long, thin, wispy streamers. They are commonly known as "mare's tails" because of their appearance.Image courtesy of Lisa Gardiner

Cirrus CloudsCirrus clouds may appear even over some of the world's driest areas, such as the high Atacama Desert of northern Chile.Image courtesy of Caspar Ammann
Cumulonimbus CloudsThis cumulonimbus cloud has the characteristic anvil-shaped top. Image courtesy of the UCAR Digital Image Library
Cumulonimbus CloudsThis photograph of a cumulonimbus cloud was taken near Fort Lupton, Colorado. You can see some towers growing in this cloud.Image courtesy of Gregory Thompson
Cumulonimbus CloudsThis cumulonimbus cloud is well-developed and shows the characteristic anvil-shape.Image courtesy of Roberta Johnson
Nimbostratus CloudsThis image of nimbostratus clouds was taken in Seattle, WA. Notice the rain falling out of the clouds, as well as the rainbow!Image courtesy of Peggy LeMone

Think about cleaning your room.
Are you the type who rushes and puts everything in piles, or do you slowly put everything back in
its place all over the room?
Which style of room cleaning would be like a Cumulus Cloud, and which one would be like a
Stratus Cloud?
Weather and ClimateWeather and Climate
Fog:A stratus-like cloud that develops at ground level.
Nimbus:A cloud that usually brings rain will have nimbus,
meaning “rain,” in it's name.
Weather and ClimateWeather and Climate
Rain:Water droplets in clouds combine and become
large and heavy enough to fall.
Sleet:Raindrops freeze as they fall through a layer of
cold air.
Weather and ClimateWeather and Climate
Hail:Frozen raindrops become coated with water, which then freezes This process then repeats.
Snow:Water vapor condenses as ice crystals, not water
droplets.
Weather and ClimateWeather and Climate
Thunderstorms:Occur when hot, humid air rises very quickly and
cools.
Bonus Thunderstorms are:
- The most common type of severe weather- Thunderstorms are associated with dark
Cumulonimbus clouds.
Thunderstorms @ BrainPop
Weather and ClimateWeather and ClimateLightning:
A bright, powerful flash of light caused by moving electric charges.
How Lightning Strikes:“When the negative charge in the cloud becomes
great enough, it seeks an easy path to the positively charged ground below. The negative
charge sends out a feeler, called a stepped leader, which is a series of invisible steps of
negative charges.”LiveScience.com
Weather and ClimateWeather and ClimateThunder:
Thunder is the sound of air rapidly expanding because of the huge and sudden temperature
change from lightning.
“The air around a lightning bolt is superheated to about 54,000 degrees Fahrenheit (five times
hotter than the sun!). This sudden heating causes the air to expand faster than the speed
of sound, which compresses the air and forms a shock wave; we hear it as thunder.”

Weather and ClimateWeather and Climate
Thunderstorms often occur in the summer, when very warm air over the hot land rises quickly into
much cooler air.
Weather and ClimateWeather and Climate
Tornado:A violent, spinning funnel of air that extends from
the bottom of a thundercloud to the ground.
Tornadoes @ BrainPop
Weather and ClimateWeather and ClimateHurricane:
A huge, powerful storm that produces extremely strong winds and heavy rain over a large area.
It begins when a large body of air with very low pressure forms over tropical ocean water.
The low-pressure area gains moisture and energy from the warm ocean waters.
Winds increase in speed and being to blow in a circular pattern creating a tropical storm.
When the winds reach 119kph the storm is classified as a hurricane.
