Anticyclones. Anticyclones are the opposite of depressions [depression: In meteorological terms, a depression is an area of low air pressure. ] - they are an area of high atmospheric pressure where the air is sinking.1  As the air is sinking, not rising, no clouds or rain are formed. 2  The absence of fronts means winds may be very light. 3  Consequently, high-pressure areas are often associated with settled, dry and bright conditions. 4  In summer, anticyclones bring dry, hot weather. 5  In cold ... This is because as the air sinks it warms, meaning it can hold more water. 2  The absence of fronts means winds may be very light. 3  Consequently, high-pressure areas are often associated with settled, dry and bright conditions. 4  In summer, anticyclones bring dry, hot weather.
