Wind Velocity is the speed and direction of air flowing across the sea surface. Mean Wind Velocity represents the average wind speed relative to North True. Directions include Northward and Eastward vector components based on the direction the wind is moving toward (Note: this perspective is standard for oceanography but is the reverse of what is common in meteorology which describes the direction the wind is coming from, e.g. Westerly, Easterly).
