Cup Anemometer Diagram - How Wind Speed Is Measured #3763231 (License: Personal Use)

This black-and-white line illustration depicts a classic cup anemometer, featuring four hemispherical cups mounted on horizontal arms that rotate around a central vertical shaft. The rotation speed correlates directly with wind velocity, making it a reliable tool for meteorological observations. The base includes a stable mounting platform for field or rooftop installation.

Used in educational materials, weather station guides, and STEM resources to explain wind measurement principles; targets students, teachers, hobbyists, and professionals seeking foundational knowledge of meteorological instruments.
