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.

The Key Words for today are:

• Temperature• Wind Direction• Visibility• Air Pressure• Precipitation• Wind Speed• Cloud Cover

• Can you think of definitions Can you think of definitions for these?for these?

How fast the wind

is blowing…


• Can you think of definitions for these?Can you think of definitions for these?


Where the wind is

blowing from…

Water falling from the sky

(rain, hail, sleet, snow)

How far ahead we can see

on a foggy day

Exactly how hot or cold it is...

How ‘heavy’ the air is…

How much of the sky

is hidden by clouds

Now fill in the first two columns in your table

Weather Term…. Means… Usually given… Measured Using…Temperature

How heavy the air is

Visibility

What are weather terms usually given as?

• We use centimetres or metres for measuring small distances

• The amount of Diet Coke in a bottle is given in litres

• The cost of something is given in £ and pence.

• What about the Weather Terms we have looked at?.........

• Millibars

• Oktas (Eighths of sky)

• Miles per hour (mph)

• ° C (celcius or fahrenheit)

• Compass point (N, E, S, W)

• Metres or kilometres

• Millimetres (mm)

Now complete the 3rd column in your table

Weather Term…. Means… Usually given… Measured Using…Temperature

What equipment do we need to measure the weather?

• Thermometer• Anemometer• Barometer• Weather Vane• Rain Gauge• Visibility Meter• Your Eyes Next

Now complete the last column in your table

Weather Term…. Means… Usually given… Measured Using…

Temperature

How heavy the air is

Visibility

You should now have a completed table of ways to measure the weather

Measuring Weather• L.O: To know different pieces of equipment for
