A hemispherical-cup anemometer of the type invented in 1846 by John Thomas Romney Robinson. In meteorology, an anemometer (from Ancient Greek άνεμος (ánemos) 'wind' and μέτρον (métron) 'measure') is a device that measures wind speed and direction. It is a common instrument used in weather stations.
1662 – Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge. [34] 1667 – Robert Hooke builds another type of anemometer, called a pressure-plate anemometer. [22] 1686 – Edmund Halley presents a systematic study of the trade winds and monsoons and identifies solar heating as the cause of atmospheric motions.
A hemispherical cup anemometer of the type invented in 1846 by John Thomas Romney Robinson. John Thomas Romney Robinson (23 April 1792 – 28 February 1882), usually referred to as Thomas Romney Robinson, was an Irish astronomer. He was the longtime director of the Armagh Observatory, one of the chief astronomical observatories in the UK of its ...
An anemoscope c1920s built by the American instrument maker Julien P. Friez & Sons is in the collection of Harvard university was designed to be used as part of an automatic wind recorder alongside a wind speed measuring anemometer. [3] Today anemoscopes are used in meteorological stations, and in transport especially boats.
Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [1] In 1607, Galileo Galilei constructs a thermoscope. In 1643, Evangelista Torricelli invents the mercury barometer. [1] In 1662, Sir Christopher Wren invented the mechanical, self
1838: Screw-pile lighthouse invented by Alexander Mitchell. [22] 1843: Quaternion discovered by William Rowan Hamilton. [23] 1844: Hypodermic needle invented by Francis Rynd. [24] 1846: Cup anemometer invented by Thomas Romney Robinson. [25] 1848: Kelvin scale invented by William Thomson. [26] 1851: Binaural stethoscope invented by Arthur ...
The anemometer of the earth inductor compass on the Spirit of St. Louis shows as a small "T" shape above the fuselage behind the wing. The Earth inductor compass (or simply induction compass [1]) is a compass that determines directions using the principle of electromagnetic induction, with the Earth's magnetic field acting as the induction field for an electric generator.
