| |Meaning=(''Also called'' feather.) A means of representing [[wind speed]] in the [[plotting]] of a [[synoptic chart]]; it is a short straight line drawn obliquely toward lower [[pressure]] from the end of a [[wind-direction shaft]].
| |
| |Explanation=In the commonly used [[five-and-ten system]], one barb represents 10 knots and a half-barb represents 5 knots. Previously, a full barb was used to represent a [[Beaufort force]] of 2, with a half- barb to represent a Beaufort force of 1. Customarily, the barb is often drawn obliquely or perpendicular to the [[wind direction]]. <br/>''See'' [[pennant]].
