The scales used to represent the different velocities of winds and how they attain hurricane intensity.
Explanation:
- The Beaufort wind scale was developed by Sir Francis Beaufort, in 1805. It is used for mapping the speed of the winds.
- The wind force that is less than 1 knots is classified as calm and gradually moves on the sea surface and the smoke rising on land.
- Wind of 1 to 3 knots in light air and is indicated by the still wind vanes. The 4 to 6 knots is a light breeze and is wind felt on the face, leaves rustle.
- The velocity of 7 to 10 knots is called a gentle breeze, large wavelets, small and large twigs move constantly. The 11 to 16 knots is a moderate breeze that lifts dust, paper and loses items.
- 17 to 20 knots is classified as a fresh breeze and are moderate waves small trees and leaves move. The 22 to 27 is a strong breeze, larger trees move, and whistling of wires.
- The 28 to 33 is a near gale were sea heaps up to 13-19 feet and difficult is felt while walking.
