Anticylones

Question 1

What are anticyclones

Answer 1

Areas of relatively high atmospheric pressure

Question 2

How are anticyclones represented on a weather map

Answer 2

A system of closed isobars with pressures increasing towards the centre

Question 3

How do anticyclones move

Answer 3

Slowly and may remain stationary over an area for several days or even weeks

Question 4

What happens to the air in an anticyclones

Answer 4

It subsides (falls from above), warming as it falls = produced a decrease in its relative humidity which leads to a lack of cloud development, and dry conditions

Question 5

What are the isobars like with an anticyclone

Answer 5

Usually far apart, and therefore there is little pressure difference between the centre and edges of the anticyclones

Question 6

Winds in an anticyclone

Answer 6

Weak, and flow gently outwards in a clockwise direction in the northern hemisphere, anti-clockwise in the Southern Hemisphere
