who invented it?
Leon Battista Alberti
Anemometer
Leon Battista Alberti (1404–1472) is said to have invented the first mechanical anemometer around 1450.
most of the u.s. is situated in which zone of prevailing surface winds Northern temperate zone how is nature affected because of this prevailing winds? Insects are swept along by the prevailing winds, while birds follow their own course. In the Great Plains, wind erosion of agricultural land is mainly driven by the prevailing wind. Because of this, wind barrier strips have been developed to minimize this type of erosion. does it cause impact on trades? Yes - the trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere. The trade winds act as the steering flow for tropical cyclones that form over world's oceans, guiding their path westward. how is wind rose related to it? It is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. It shows the frequency of winds blowing from particular directions. how is the speed of the wind measured? Anemometer what does cup anemometer refer to? A simple type of anemometer with four hemispherical cups mounted on horizontal arms, which were mounted on a vertical shaft. what are ultrasonic anemometer for? They measure wind speed based on the time of flight of sonic pulses between pairs of transducers. Ultrasonic anemometers can take measurements with very fine temporal resolution, 20 Hz or better, which makes them well suited for turbulence measurements. where are these instruments placed to measure it? In open rural terrain at a height of 10 meters. how is its effect seen on icing? Anemometry is also required in monitoring and controlling the operation of wind turbines, which in cold environments are prone to in-cloud icing. Icing alters the aerodynamics of an anemometer and may entirely block it from operating. Therefore, anemometers used in these applications must be internally heated.

Anemometer [SEP] History
The anemometer has changed little since its development in the 15th century. Leon Battista Alberti (1404–1472) is said to have invented the first mechanical anemometer around 1450. In following centuries, numerous others, including Robert Hooke (1635–1703), developed their own versions, with some being mistakenly credited as the inventor. In 1846, John Thomas Romney Robinson (1792–1882) improved upon the design by using four hemispherical cups and mechanical wheels. In 1926, Canadian meteorologist John Patterson (January 3, 1872 – February 22, 1956) developed a three-cup anemometer, which was improved by Brevoort and Joiner in 1935. In 1991, Derek Weston added the ability to measure wind direction.
