Illustration of a wind vector, the two- or three-dimensional vector describing the instantaneous wind magnitude and direction at a point (often using Cartesian coordinates; i.e. X and Y wind vectors). The term can also apply to the resultant wind vector which is sometimes drawn as an arrow with length proportional to wind speed
