Historical Anemometer Diagram - Measuring Wind Speed Since the 19th Century #10016 (License: Personal Use)

This vintage line drawing depicts a traditional cup anemometer, where wind rotates four hemispherical cups mounted on horizontal arms, driving a gear system that records revolutions via dials in the base. The instrument exemplifies early meteorological engineering, combining fluid dynamics with mechanical precision to quantify wind velocity. Its robust, portable design made it widely adopted for weather stations and field observations before digital sensors.
