eddy
eddy The motion of a fluid in directions differing from, and at some points contrary to, the direction of the larger-scale current. In air, eddies vary in size from small-scale turbulence (which can transport dust and diffuse pollutants) to large-scale movements (e.g. cyclone and anticyclone cells) within the general global circulation of the atmosphere.
