Sorry, no winner this week. Here is my weather quiz question for the last time. A measuring scale was devised for determining wind speed over land and over bodies of water without the use of instruments. What is it called and who devised it? The Beaufort scale was created in 1805 by Sir Francis Beaufort, an Irish-born British admiral and hydrographer. The scale that carries Beaufort’s name had a long and complex evolution, from the previous work of others, to when Beaufort was a top administrator in the Royal Navy in the 1830s. In the early 19th Century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective – one man’s “stiff breeze” might be another’s “soft breeze”. Beaufort succeeded in getting things standardized. The scale was made a standard for ship’s log entries on Royal Navy vessels in the late 1830s and was adapted to non-naval use from the 1850s, with scale numbers corresponding to cup anemometer rotations. Here’s a graphic showing the scale. I’ll have another weather quiz question for you starting next Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.
