GEOLOGY

Detailed explanation-1: -One of the first scales to estimate wind speeds and the effects was created by Britain’s Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12.

Detailed explanation-2: -He surveyed the coasts of South America and Turkey, and at home in 1803-04 he also helped establish a telegraph line from Dublin to Galway for his inventor brother-in-law, Richard Lovell Edgeworth. Francis was the creator of the now-famous Beaufort Scale in 1806 for indicating wind force.

Detailed explanation-3: -1. Light winds at 1-5 kph (1-3 mph). Smoke drift shows wind direction. 2. Light breeze at 6-11 kph (4-7 mph).

Detailed explanation-4: -In 1805, a British Naval officer called Francis Beaufort introduced a scale from 0-12 for measuring the speed of the wind at sea. Admiral Beaufort developed the scale based on his observations of the wind and waves and used everyday terms for each level of his scale.
