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
