What are winter and summer anticyclones?

Winter and summer anticyclones are high-pressure systems characterized by descending air that leads to clear skies and stable weather conditions. In winter, these anticyclones often bring cold, dry air, leading to frosty conditions and potentially severe cold spells. In contrast, summer anticyclones are associated with warm, dry weather, often causing heatwaves and limited precipitation. Both types can significantly influence regional climates and weather patterns.
