Presentation on theme: "Clouds and Weather Prediction. In this activity you will: Learn about the types of clouds, how they are formed, and the weather each might predict. Illustrate."— Presentation transcript:
What are clouds? How are they made? NOVA How are they made? NOVA How are they made? NOVA A cloud is made up of tiny water droplets and/or ice crystals, a snowflake is a collection of many ice crystals, and rain is just liquid water.
Cloud Types Names of specific types of clouds are created by combining the name of the cloud's shape with its height.
Cloud Types The presence of clouds in the sky is one type of signal to meteorologists that there will be changes in the weather. Predicting the weather requires the understanding of the different types of clouds.
Cloud Formation Clouds form when solar heating of the earth’s surface warms the air near the ground. This air begins to rise and it expands and cools. Water vapor then condenses on small dust particles suspended in the air and these combine to form clouds.
Cloud Formation Why are there so many different types of clouds? Why are there so many different types of clouds? Why are there so many different types of clouds? The type of cloud created is determined by how fast the air rises.
Clouds There are 3 main types of clouds: Cumulus or fluffy clouds form when air is forced up rapidly and therefore rises higher. Cumulus
Clouds Stratus clouds are layered clouds that form when air that is forced up slowly. Stratus
Clouds Cirrus clouds are thin feathery clouds. Cirrus
Only light precipitation, generally in the form of drizzle, occurs with stratocumulus clouds. To distinguish between a stratocumulus and an altocumulus cloud, point your hand toward the cloud. If the cloud is about the size of your fist, then it is stratocumulus precipitationaltocumulus
Nimbostratus They are dark gray with a ragged base. Nimbostratus clouds are associated with continuous rain or snow. Sometimes they cover the whole sky and you can't see the edges of the cloudrainsnow
Vertically Developed Clouds Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. The cloud tops designate the limit of the rising air.
Vertically Developed Clouds Harmless fair weather cumulus can later develop into towering cumulonimbus clouds associated with powerful thunderstorms.
Weather Predictors Clouds, in many cases, foreshadow incoming weather and assist in forecasting.
Four Types of Clouds GO Given the blue paper and a small piece of white chalk, you are to draw each of the following types of clouds: cumulus, cirrus, stratus, and cumulonimbus Divide your paper into four equal parts along. Fold into fourths. Turn down the center corner of your page so that when you open up the page you have created a graphic organizer that now has a diamond in its center. Write Cloud Types in this center diamond. Label one corner cumulus, cirrus, stratus, and cumulonimbus. In the appropriate box illustrate each type of cloud using your piece of chalk.
Summarizer Using the descriptions given, write the name of the cloud type, a description of the cloud, and the kind of weather associated with each one. (wkst 98)
