The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage The scale was derived to help the sailing ships of that time operate under a variety of wind and sea conditions. The basic scale had 13 categories from 0 (calm winds) to 12 (hurricane force winds). Because it was impossible to ascertain accurate wind speeds on a sailing vessel in those days, there were no specific wind speed values given

The Beaufort Scale has become the standard method of judging wind force. It is not the oldest, since rating the strength of wind by number and/or assigning names to the ratings had been done for some time. In 1806 Francis Beaufort (later Admiral and Sir) wrote out a numerical scale in his log His wind scale ran from 1 to 8, describing each force by what he observed at a particular windmill, the Austhorpe Mill near his home. For example, number 2, Breeze, was Sufficient to move the branches of trees, and Mill from 6 to 9 turns per minute, while at number 5, Very Fresh, Wind growing noisy, and considerable agitation of Trees, Mill 18 [turns per minute] to ¾ Cloth Description of the Beaufort Wind Scale.

The scale was simple and very similar to one that Alexander Dalrymple had written in a book in 1789. A year later he added some criteria to the 0-12 scale that indicated how much of a ship's sails would be employed by a British man-of-war under each condition A system of estimating and reporting wind speed devised by British Rear-Admiral, Sir Francis Beaufort (1774-1857) in 1805, based on observations of the effects of the wind.

Beaufort wind scale or Beaufort wind force scale was created by British Admiral Sir Francis Beaufort in 1805. At that time, ships included fishing boats and warships, where canvas sails were deployed to ride the waves using wind power. Anemometer was not yet available. Wind and waves are inter-related It is a calculated value and other values cannot be calculated from it. Generally, all wind speeds faster than 11 Beaufort are grouped together to 12 Beaufort.

Force 0 is calm, no wind. From there, it describes the. A warm-core non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters, with organized deep convection and a closed surface wind circulation about a well-defined center. Once formed, a tropical cyclone is maintained by the extraction of heat energy from the ocean at high temperature and heat export at the low temperatures of the upper troposphere The scale is roughly logarithmic, like the Richter Scale for earthquakes. A typical Category 2 storm could produce 10 times the damage of a typical Category 1 because wind power or force increases exponentially with increases in wind speed and therefore, so does potential damage wind scale. wind scale: translation. wind scale. n. a scale used in meteorology to designate relative wind intensities, as the Beaufort scale.
