A graphical device used on weather maps to describe the
intensity and direction of the wind at some specified location.
HOW TO READ A WIND BARB:
The barbs are comprised of a
tail, consisting of lines and/or flags, and a bare point. The intensity of the wind is represented by the number of lines
and/or flags on the tail. Each full line equals 10 knots (kts) and a
smaller half-line is 5 kts. A flag (triangle) is equal to 50
kts. Every item should be added together to determine
the magnitude of the wind. A circle represents calm conditions.
The wind direction is determined by the orientation of the
barb on a 360 degree compass-like circle. Wind blows FROM the tail to
the bare point. SEE THE GRAPHICS BELOW FOR A VISUAL DEPICTION.
