where are these instruments placed to measure it?
In open rural terrain at a height of 10 meters.
Anemometer
In order for wind speeds to be comparable from location to location, the effect of the terrain needs to be considered, especially in regard to height. Other considerations are the presence of trees, and both natural canyons and artificial canyons (urban buildings). The standard anemometer height in open rural terrain is 10 meters.
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.
