Leon Battista Alberti invented the first anemometer in 1450 A.D. His invention was a disk that was perpendicular to the direction of the wind, which measured wind speed.Continue Reading
The type of anemometer that is common today, the cup-shaped variety, was not invented until 1846 by John Thomas Romney Robinson. He used four cups and wheels on his anemometer. The design was improved again in 1926 by John Petterson, who simplified the design to 3 cups.
Today's anemometers measure wind speed, wind pressure and wind direction. Wind speed is calculated by counting the number of times the cups on the instrument turn. They help meteorologists analyze how weather works, which assists with weather predictions.Learn more about Inventions
An anemometer is an instrument used to measure wind speed. It is used in weather forecasting, aerial navigation, weather recording, aircraft testing and ventilation systems. Anemometers generally use several cups to catch wind and turn a dial that displays wind speed.Full Answer >
An anemometer is an instrument that measures wind speed. The cup anemometer, the most common kind, consists of three or four cups connected to a shaft. When the wind blows, the cups spin around, turning the shaft, which has a sensor that gives the wind speed.Full Answer >
Hurricane Patricia, a storm that made landfall on the Western Pacific coast of Mexico, had a maximum measured wind speed of 198 miles per hour, the highest recorded sustained hurricane wind speed, as of 2015. However, scientists record much higher wind speeds with typhoons and cyclones.Full Answer >
The inventor is not known, but the earliest documented use of a candle clock is from approximately 500 A.D. in China. A Chinese poem by You Jiangu describes a clock that uses six candles that are marked in increments of 20 minutes. Each candle takes four hours to burn.Full Answer >
