Which type of weather system is characterized as downward, outward, and anti-cyclonic?

A high pressure system is characterized by downward movement of air, which results in outward flow from the center of the system. This downward motion suppresses cloud formation and creates clear skies, making high pressure systems generally associated with fair weather. The air in a high pressure system moves in a clockwise direction in the Northern Hemisphere and counterclockwise in the Southern Hemisphere, which is aligned with the definition of anti-cyclonic flow.

This behavior contrasts with low-pressure systems, where air rises, leading to cloud formation and precipitation. Frontal systems involve the interaction of different air masses and do not inherently represent the stable, calm conditions typical of high pressure. Mixed systems may involve elements of both high and low pressure but do not specifically convey the defined characteristics of downward, outward, and anti-cyclonic motion associated with high pressure systems.
