Question 1

What device is used to measure wind speed?

Answer 1

The anemometer

Question 2

What units are used by an anemometer?

Answer 2

km/h

Question 3

How does an anemometer work?

Answer 3

It is connected to a meter, and the little cups rotate. This is converted to wind speed.

Question 4

What device is used to measure air pressure?

Answer 4

The barometer.

Question 5

How does a barometer work?

Answer 5

A barometer acts like a balance that ‘balances’ the weight of the atmosphere against the weight of a mercury column.

Question 6

What device is used to measure rainfall?

What site factors are needed for an anemometer to work?

Answer 17

It should be on top of buildings so that it can record the true wind speed unaffected by obstacles such as other buildings and trees that slow it down.

Question 18

What site factors are needed for a rain gauge to work?

Answer 18

It should be away from overhanging buildings and trees that may drip onto it. It should also be put into the ground for stability, or onto a firm base.

Question 19

How far away from the ground should a rain gauge ideally be?

Answer 19

30cm

Question 20

What site factors are needed for a sunshine recorder to work?

Answer 20

It should be off the ground, facing south in the northern hemisphere so that it is exposed to the sun.
