The document provides information about weather forecasts and reports. It discusses how weather forecasts predict future conditions and are made by meteorologists. It also explains that weather reports describe actual past weather conditions and include tables of weather data. The document aims to teach students to read weather forecasts, understand weather symbols, and create their own basic weather maps and reports.
Clouds
What are clouds?
A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.
Why do clouds float?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
There are 3 main types of clouds:
Cirrus or thin feathery clouds
Stratus or layered clouds
Cumulus or fluffy clouds
Cirrus Clouds
Are the most common of the
high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours.
Stratus Clouds
are uniform grayish clouds that often cover the entire sky. They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds.
Cumulus Clouds
are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called "fair-weather clouds". The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
The Importance of Clouds
Clouds help regulate Earth's energy balance by reflecting and scattering solar radiation and by absorbing Earth's infrared energy.
Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.
Clouds indicate what type of atmospheric processes are occurring (e.g., cumulus clouds indicate surface heating and atmospheric turbulence).
Clouds help redistribute extra heat from the equator toward the poles.

4. Weather Forecast
• A weather forecast is a prediction of
the weather
• People who make these predictions are
known as meteorologists
• Lets have a look at a forecast;
• In the back of your books write down
the forecast for anywhere you see
5. Weather Forecasts
• Before satellite images, we used to use
symbols to demonstrate the weather
• On your worksheet, try to match the
symbol with its description
• Use a ruler to connect them
9. Weather Report
• A weather report is an account of what
weather has actually happened.
• The information is put into tables
• Using the map, can you display the
following weather conditions
10. • Using the Canbury Weather
Diary, describe the weather over the
last week. Use the figures to explain
yourselves
11.
12. Plenary
• Using the newspapers
• Find out the weather for a location of
your choice
• Use the weather report to do this
