What is the difference between depressions and anticyclones?

Depressions are areas of low atmospheric pressure caused by rising air. The rising air causes clouds to form, typically leading to rainy weather. The presence of air fronts (boundaries between air masses of different temperature/density) in depressions can also cause windy conditions. Anticyclones are the opposite- they are areas of high atmospheric pressure, where the air is sinking. They bring dry and settled weather, which can be either hot or cold depending on the season- in winter, the lack of cloud cover during an anticyclone means there is little insultion of heat from the sun and conditions are cold, whereas in summer, conditions are hot as there is no cloud to shield the strong sun. Winter anticyclones can also bring fog or mist as the cool temperatures allow the water vapour in the air to condense at low altitudes.
