The speed of the wind is between 64 and 71 knots.
Remember that a knot is one nautical mile (nm) per hour.
A nautical mile is the traditional way of measuring distances at sea. It is equal to
1,852 metres. The word nautical (like the word maritme) means ‘to do with the
sea or ships’.
A hurricane is called Wind Force 12 on the Beaufort Wind Force Scale. Sailors
use this scale to describe the force of the wind. We will learn about this in another
lesson. |
