Cloud Presentation
By: Brandon Bond
Basic Cloud Types
• Cumulus– Puffy, white clouds with flat bottoms
• Stratus– Form in layers
• Cirrus– Thin, feathery, white clouds
Cumulus Clouds
• Formed when warm air rises.• Look like piles of cotton balls.• Generally indicate fair weather but, when they
get larger they produce thunderstorms.• Cumulonimbus clouds produce thunderstorms
Cirrus Clouds
• Form when the wind is strong.• Look like thin, feathery white clouds.• If they get thicker then they indicate that a
change in the weather is coming.
Stratus Clouds
• Formed from a gentle lifting of a large body of air into the atmosphere.
• Look like white layers in the sky.• Weather can be foggy and/or light to heavy
continuous rain.• Nimbostratus clouds are dark clouds that produce the
rain.
Altitudes
• Clouds are also classified by the altitude at which they form.– High
• Begins with prefix cirro-• Made up of ice crystals due to cold temperatures.
– Middle• Begins with the prefix alto-• Made up of water drops and ice crystals
– Low• No prefixes.• Made up of water drops.

Cirrostratus clouds are a thin, transparent, whitish layer made up of ice crystals.GLOBE Cloud Exploration

Altocumulus clouds look like waves of the sea with white and grey coloring and shadows.GLOBE Cloud Exploration
Altocumulus clouds are almost always water droplets, and rarely ice crystals.GLOBE Cloud Exploration
Nimbostratus with mountain rain and snow showersGLOBE Cloud Exploration
Nimbostratus is a very dark and grey colored cloud layer that blots out the light of the sun.GLOBE Cloud Exploration
Altostratus clouds form a bluish or greyish veil that totally or partially covers the sky.GLOBE Cloud Exploration
The light of the sun can be seen through Altocumulus clouds but there is no halo effect.GLOBE Cloud Exploration
Cumulonimbus are very large, heavy and dense cloudsGLOBE Cloud Exploration
Cumulonimbus clouds have a generally flat, dark surface with very tall and large tops like the shape of a massive mountain and are associated with thunder and lightning.GLOBE Cloud Exploration
