My audience will be Middle School and Jr. High School students and I will be teaching them the types of clouds using various resources.
This will be the opening picture, this is a good visual reference for the students because it lists the clouds names shows their appearances and the average altitude for each cloud. Before I bring the picture in, I have a learning moment to see if the students know any of the cloud names already! 2 nd week changes (fly in picture)
Cumulus clouds have three different types and I will explain these different types of cumulus clouds and let them take notes. 2 nd week changes (text box used)
These clouds usually bring heavy storms and will have lightning with them.
These clouds are more commonly known as fog or mist instead of clouds, these clouds are very low because they have lots of precipitation and form when its cool therefore sinking to the ground.
These clouds form on blue skied days up high and are usually moving pretty fast.
Altocumulus clouds are very high up in the atmosphere so they aren't influenced by thermals, this is why they only create light rain.
These clouds are very high up in the sky and cause pretty sunsets because of the light bouncing off of them, they do not create precipitation.
More commonly known as the “rain” cloud, these clouds bring heavy storms and have a slow rainfall, this cloud can also make snow or sleet.
These wispy clouds form on bright sunny days and are usually seen quickly through the sky. These clouds do not create precipitation.
Very similar to the cirrus cloud, but the only difference is this cloud does produce precipitation and lots of it, it you see lots of these clouds together you will know you are going to have bad weather soon. 2 nd week changes arrow for emphasis and text box
Exactly like the cirrus cloud but are not easily spotted, and when they are spotted they produce optical effects. These clouds do not produce precipitation.
Answers: left to right, top to bottom – cirrostratus, cirrus, cirrocumulus, altostratus, altocumulus, cumulonimbus, stratocumulus, stratus, nimbostratus, cumulus, fog 2 nd week addition
Cumulus Clouds • There are three types of cumulus clouds: • humilis are wider than they are tall • mediocris are as wide as they are tall • congestus are taller than they are wideCan “grow” onsunny days
Cumulonimbus CloudsForm best under these conditions:• Lots of warm and moist air• Increasing winds make the cloud slant forward.• The atmosphere around the cloud needs to be “unstable” Thunderstorms on the way!
Stratus Clouds• Stratus clouds are formed when large air masses cool, also known as fog or mist.• Stratus clouds are also the lowest forming clouds. Light rain most likely
Stratocumulus Clouds• Stratocumulus clouds are textured and puffy.• Stratocumulus clouds usually form from cumulus or stratus clouds. Snow is possible
Altocumulus Clouds• Altocumulus clouds are very high in the sky, so they are usually above the influence of thermals.• The usual precipitation is light rain. ! This type This type makes really makes really cloudy skies! cloudy skies!
Altostratus Clouds• Altostratus Clouds altitude is between 6,500 and 23,000 ft• But since they are up so high they are the reason for pretty sunsets.
Nimbostratus Clouds• Usually thick and wet, with lots of precipitation that is steady and slow.• Formed from altostratus clouds when they collect water.
Cirrus Clouds• Cirrus clouds are the highest of all clouds and made of ice crystals.• Cirrus clouds have no visible precipitation.
Cirrocumulus Clouds • Another cloud mostly made of ice crystals. • Lots of large cirrocumulus clouds may indicate bad weather. • Formed in the troposphere in high winds.Indicates lotsof precipitationon the way!
Cirrostratus Clouds• Cirrostratus clouds are usually difficult to spot.• Cirrostratus clouds produce a variety of optical effects.
