Explain the difference between depressions and anticyclones and what causes each

Depressions:

  • Depressions are low pressure areas which are caused when air rises
  • The air rises because it is warmer than air around it or it can be forced up by high land
  • As the air rises it cools and clouds form
  • This causes unsettled changeable weather
  • Depressions are often associated with fronts
  • A front is where hot air is next to cold air
  • The warm air is forced upwards, it cools and condenses causing clouds and rain

Anticyclones:

  • Anticyclones are much the opposite of depressions
  • Anticyclones are associated with high pressure which is caused by sinking air
  • They bring settled / good weather
  • Because air is sinking, air is not able to rise from below so no clouds or rain are able to form
  • Anticyclones do bring fog and mist which in cold weather can lead to bad road conditions
