What characterizes an anemometer?

An anemometer is a device specifically designed to measure wind speed. It typically consists of rotating cups or blades that turn in the wind, with the speed of rotation being directly proportional to the wind speed. This characteristic makes it an essential instrument for meteorologists and aviators who need to assess wind conditions for various applications, including weather forecasting, flight operations, and maritime activities. By providing accurate measurements of wind speed, an anemometer plays a crucial role in understanding weather patterns and conditions that may affect navigation and safety in both aviation and maritime contexts.
