The specialsymbol for the wind barbs is a flag consisting of lines which are perpendicular and to the left of thewind shaft using the scale as indicated.2 barb (5 pixels in length) = 5 knots, example: 270° 65 kts1 barb (10 pixels in length) = 10 knotsFull triangle (10 pixels in length and 4 pixel base) = 50 knotsShaft length = 20 pixelsFor the VAD Product:The velocity data will be plotted as single points on the grid of velocity vs. azimuth. The best fitfunction will be plotted over the field of velocity points as a linked vector in a contrasting color.The span of velocity data displayed on the grid is as follows:VelocitySpan of Velocity data (grid)
