Wind speed is a measurement of the speed of movement of the air, and is typically reported in miles per hour (mph) or kilometers per hour (kph). Reports for maritime and aeronautical operations may use those or knots (nautical miles per hour).
The Saffir-Simpson Hurricane Wind Scale measures the amount of wind damage caused by hurricanes. The speed of the wind determines the category of the storm. Categories range from 1 to 5.Currently, the Saffir-Simpson Hurricane Wind Scale takes into account only wind speed. Since its development in 1971, it has gone through a few modifications. An earlier version used storm surge and central pressure as well as wind speed to determine damage.This scale was known as the Saffir-Simpson Hurricane Scale.ategories range from 1 to 5.
