Extreme Weather and Climate Lesson 2 :How do we measure weather?
Measuring Weather • L.O: To know different pieces of equipment for measuring weather and the units of measurement used. • All pupils will be able to: Give examples of how some types of weather are measured and the correct units measured in. • Most Pupils will be able to: Give the equipment and correct unit of measurement for various types of weather and identify most of these from pictures. • Some pupils will have taken this further and will be able to: Know all the different types of equipment and units of measurement and identify these correctly and accurately.
Definitions • “ The weather is what happens in the atmosphere on a daily basis, it changes frequently,” (which is why it is difficult to measure!)
Why do people measure the weather? • To plan ahead – decide when to do certain things • To plan holidays at the right time of year • To decide what to wear • To prepare for bad weather e.g. flooding or heavy snow • For people’s jobs e.g. people who pilot planes and ships, farmers and mountaineers
How do people measure the weather? • Meteorologists are people who study and measure the weather. • The weather is observed by weather stations based on land and equipment carried on planes, ships, weather balloons and satellites. • They tell us what the temperature is, how much rain fell, how fast the wind is blowing and what direction it’s coming from, as well as how cloudy it is.
