Anticyclones are the opposite of depressions - they are an area of high atmospheric pressure where the air is sinking.
- As the air is sinking, not rising, no clouds or rain are formed. This is because as the air sinks it warms, meaning it can hold more water.
- The absence of fronts means winds may be very light.
- Consequently, high-pressure areas are often associated with settled, dry and bright conditions.
- In summer, anticyclones bring dry, hot weather. In winter, clear skies may bring cold nights and frost.
- In cold conditions, anticyclones may also bring fog and mist. This is because the cold forces moisture in the air to condense at low altitudes.
