ADDITIONAL FEATURES
To interpret wind speed, add the values of each of the
wind speed barbs. In Figure 12-49, there are two long
barbs (10 knots each) and one short barb (5 knots each).
Thus, the total wind speed is 25 knots. Adding the gust
offset to this figure gives winds gusting to 36 knots. Thus,
the symbol in Figure 12-49 indicates the surface wind at
KFRM is coming from a direction of 300° at a speed of
25 knots, gusting to 36 knots or greater. The data age is
11-20 minutes old.
