What does a full barb on a surface map indicate regarding wind speed?

A full barb on a surface map indicates a wind speed of 10 knots. In meteorological terms, wind speed is represented by barbs on a weather map. Each full barb corresponds to a specific increment, which in this case is set at 10 knots. Understanding these visual indicators is crucial for interpreting wind conditions accurately, which is essential for pilots and meteorologists. Thus, a full barb effectively communicates a consistent and standardized measure of wind velocity, allowing for quick assessments of weather conditions that can impact flight operations.
