Task 9A: Watch the video clip.

B: Read the notes and copy these into your book.

C: Familiarise yourself with the synoptic code, if you can print it out.

D: Worked example; draw the example into your book and include the answers to the side

E: Activity; using the code find out the weather at the 3 weather stations.

F: Activity; using the 4 weather stations, complete the table.

G: Activity; Describe the weather conditions at the 4 weather stations.

H: Read the notes on isobars and answer the questions.

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 knotsWind direction (the direction the line is pointing in) = SWCloud cover = six oktasTemperature = 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.

1. 2. 3.E

For this one they have given you the weather, you have to

draw the symbols

Now it’s your turn, using the code write the

weather forecast for

these 3 stations.

F Here we have 4 weather stations, copy the table into your book and answer the questions.

G Here we have 4 different weather stations. Use the synopticcode 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?

2. What is indicated if isobars are close together?

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