Copy and paste the link into google

•Weather is represented by specific symbols on

weather maps

•Weather maps are also called “Synoptic Charts”

Presenting Weather Data

B

These are the standard symbols used on weather stationsC

If you can, print this out and keep it beside you. You will

need it throughout the activities in this lesson

• Special symbols called the synoptic code, are used all over the world, to show all this data on weather charts.

• Information for a weather station is summarised on a chart using a circle to represent the station.

So this will be our first example, remember to use the code on the previous slide to help you.

Present weather = rain (I looked at what the dot symbol represented)Wind speed = 25 knots Wind direction (the direction the line is pointing in) = SWCloud cover = six oktas Temperature = 12

I was able to find out the weather at this weather station by using the code on the previous slide and the information given.

G Here we have 4 different weather stations. Use the synoptic code to complete the table on the next slide

When we were looking at our weather instruments, we said a

barometer was used to measure air pressure in millibars.

To show air pressure on a weather map we use isobars.

These lines on the weather map are isobars

Questions1. What do isobars measure?

Air pressure.

2. What is indicated if isobars are close together?

That it is windy.

3. Where is the highest area of pressure on this weather map?

At 1004
