Wind blows from the north-west on \( 62 \) days of \( 365 \). Its frequency in a wind rose is
Answer: B
Correct answer: 17.0 per cent
The frequency plotted on a wind rose for a sector is simply the proportion of observations from that direction:
\[ f = \frac{62}{365} \times 100 = 17.0\ \text{per cent} \]
So the north-west spoke would be drawn to a length representing 17 per cent, usually subdivided into speed bands. The figure \( 62 \) is the raw count of days rather than a frequency, and the other options do not follow from the data. Sectors of this size are what identify a prevailing wind and hence the most frequently exposed downwind area.
