Anemometer Diagram - How Wind Speed Is Measured #3763242 (License: Personal Use)

This hand-drawn schematic depicts a classic cup anemometer with four hemispherical cups mounted on horizontal arms rotating around a vertical shaft; the cups catch wind asymmetrically, causing rotation proportional to wind velocity. The central hub connects to a sensor or counter that translates rotational speed into measurable wind speed units (e.g., m/s or mph). Its minimalist design emphasizes function over form, making it ideal for educational illustrations.

Commonly used in meteorology textbooks, STEM lesson plans, weather station documentation, and科普 (science communication) websites. Matches user intent for understanding basic weather instrumentation or preparing classroom visuals.
