Wind barbs are graphical symbols used to represent wind direction and speed on maps. Each barb represents a certain value of wind speed and direction. Here's how to interpret them:
- Wind Direction: The direction from which the wind is blowing is indicated by the direction the barb is pointing in degree true. The barbed end points in the direction from which the wind is coming, and the end with a dot points in the direction the wind is blowing towards.
