WeatherQuestion 61 of 100
A METAR reads: KRDU 141753Z 21014G24KT 10SM FEW040 26/17 A3002. How should you interpret the wind group?
a.From 140 degrees true at 21 knots, with gusts to 24 knots
b.From 210 degrees true at 14 knots, with gusts to 24 knots
c.From 210 degrees magnetic at 24 knots, with lulls to 14 knots
d.From 240 degrees true at 21 knots, with gusts to 14 knots
Explanation
In a METAR wind group the first three digits are the direction the wind is blowing from, the next two are the sustained speed, and the digits after the G are the peak gust, so 21014G24KT is 210 degrees at 14 knots gusting 24 knots. METAR and TAF wind directions are referenced to true north, not magnetic north, which rules out the magnetic option. The other choices scramble the direction and speed digits or reverse the gust value, which is always higher than the sustained speed.
