Wind

Question 1

Wind causes wind?

Answer 1

By differences in air pressure.
Measured in millibars (mb) in the atmosphere.

Question 2

How does the air move at seal level?

Answer 2

Air moves from an area of high pressure to an area of low pressure.

The greater the difference in pressure, the faster the wind becomes.

Question 3

What is the Normal pressure ?

Answer 3

Approx. 1013mb.

Question 4

What is pressure depicted by?

Answer 4

Isobars meaning lines of constant pressure.

These lines are shown on weather charts. The closer together these lines are means an increased pressure gradient which forecasts higher wind speeds.

Question 5

The closer the lines of constant pressure means what?

Answer 5

An increased pressure gradient which forecasts higher wind speeds.

Question 6

Low pressure systems are referred to as ?

Answer 6

Cyclones - are associated with strong winds and stormy weather.

Question 7

High pressure systems are referred to as?

Answer 7

Anti-cyclones.
Normally associated with low winds, clear skies and droughts and can feature extreme temperatures.

In the right conditions, such systems can still produce strong winds, so their reputation for low wind speeds can be misleading.
