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. The earliest known description of an anemometer was by Italian architect and author Leon Battista Alberti (1404–1472) in 1450.
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
LLWAS I used a center field anemometer along with five pole mounted anemometers sited around the periphery of a single runway. It was installed at 110 FAA towered airports between 1977 and 1987. Windshear was detected using a simple vector difference algorithm, triggering an alarm when the magnitude of the difference vector between the center ...
Anemometer, weather vane, anemoscope A windsock (a wind cone or wind sleeve) is a conical textile tube that resembles a giant sock . It can be used as a basic indicator of wind speed and direction , or as decoration.
A CWOP home weather station. The mast supports a wind vane and anemometer, while the rain gauge and other sensors are installed near ground level.. The Citizen Weather Observer Program (CWOP) is a network of privately owned electronic weather stations concentrated in the United States but also located in over 150 countries.
He used objects and photography to create this installation. [2] His exhibitions have included installations at the High Line in New York City, 2010, and Observatory at D'Amelio Terras in New York City, 2002. [9] In 2015 Oliver created an installation Anemometer inspired by 300-year-old storms on Jupiter. [10]
Exterior of a Stevenson screen. A Stevenson screen or instrument shelter is a shelter or an enclosure used to protect meteorological instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them. [1]
