On surface weather maps, wind barb symbols primarily convey:

Wind barbs on surface maps are used to show how the air is moving at a station. The direction the barb points indicates where the wind is coming from, and the number and type of marks along the barb tell you the wind speed in knots. A long barb equals 10 knots, a short barb equals 5 knots, and a filled triangular flag represents a higher value (like 50 knots). This combination makes wind direction and speed the primary information conveyed by these symbols. Other weather aspects, such as temperature, humidity, pressure tendency, and precipitation type, are shown with different map symbols or fields.
