"In sailing, apparent wind is the speed and direction of wind indicated by a wind instrument (anemometer) on a moving craft (on water, land or ice) in undisturbed air. It is composed of the combined speeds and directions of the craft and wind observed by a stationary wind instrument—the true wind. A true wind coming from the bow increases the apparent wind induced by the speed of the craft, coming from the stern it decreases apparent wind, and coming from th… " - True wind angle
