Why this word?
If you’ve ever heard a meteorologist say the phrase “straight-line winds” on a weather report, they might have been talking about the weather system also known as a “derecho.” This Spanish word, meaning “direct, straight,” was borrowed in 1888 by chemist and naturalist Gustavus Detlef Hinrichs to distinguish a certain type of storm from the rotating winds of a tornado. According to the National Weather Service, a weather event may be classified as a derecho if the wind damage extends more than 240 miles and includes wind gusts of at least 58 mph along most of its length.
