Option 1 states that an anticyclone is a wind system with a high pressure center. This statement is correct. An anticyclone is a weather system characterized by high atmospheric pressure at its center. In an anticyclone, air descends from higher altitudes, causing the air pressure at the surface to increase. As a result, the movement of wind in an anticyclone is outward from the high-pressure center. This means that the wind blows in a clockwise direction in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

Option 2 states that in an anticyclone, the movement of wind is inward. This statement is incorrect as the movement of wind in an anticyclone is outward.

Option 3 states that the contribution of an anticyclone towards determining the weather of an area is quite significant. This statement is true. Anticyclones often bring fair weather conditions, with clear skies, light winds, and stable atmospheric conditions.

Option 4 states that the movement of wind is clockwise in an anticyclone in the Southern Hemisphere. This statement is correct. In the Southern Hemisphere, anticyclones are associated with clockwise wind circulation.
