Highs are also called anticyclones. In the Northern Hemisphere winds blow clockwise around an anticyclone, and in the Southern Hemisphere winds blow counterclockwise. The winds on the outer edges of a high blow stronger than they do towards the center. Highs usually move slowly and can remain stationary for weeks. Anticyclones bring characteristically good weather with light to moderate winds. Skies are mostly clear or have thin layers of cloud. Under certain conditions, anticyclones can also cause hazy weather or fog. When a high interacts with a low, strong winds and clear skies can be expected.
