Eddy-A circular movement of water, air, or wind that develops on the side of the main body of movement. Eddies will develop in areas adjacent to where the main body of movement is interrupted by projecting obstructions like points of land or islands. Southern California is a classic area for a near-shore south wind eddy system when strong northwesterly winds blow in the outer waters. Point Conception, the offshore islands, and low-pressure inland all contribute to the development of the eddy circulation.
