Meteorology · Beaufort Scale
On the Beaufort scale, a 'gale' (Force 8) corresponds to a wind of approximately:
- A10-15 knots
- B34-40 knots✓ Correct
- C64-71 knots
- DOver 100 knots
Explanation
Force 8 is a gale at about 34–40 knots. Marine warning categories align with this: small craft advisory below 34 kt, gale warning 34–47 kt, storm warning 48–63 kt, hurricane-force warning 64 kt and above.
