From the point of view of the wind energy industry, the cup anemometer performance is based on the transfer function: where is the wind speed, is the anemometer’s rotation frequency output, and (slope) and (offset) are the calibration coefficients.

An anemometer is a tool that is used for measuring wind speed. It is a common part of most weather stations.The first anemometer was created by an Italian named Leon Battista Alberti who lived during the Renaissance period from 1404 to 1472. However, the most common type of anemometer was created by Dr. John Thomas Romney Robinson in 1846. 0000014611 00000 n

Other scientist and climatologists may also use anemometers for a variety of experiments in order to predict future storms or simply to plot a good place for a windmill.Most anemometers are coupled with other weather measuring tools. Other interesting models were developed by Ramachandran [ 4 ] and Kondo et al. !�����BXd_�EP��n-Z��������{�w����~C��~�?�e�9�y�s�3�

Wyngaard used a 2-cup model to illustrate the “overspeeding” effect of the anemometer, that is, the cup anemometer responds quicker to wind accelerations than to wind decelerations.
