What device measures wind speed in weather observations?

Explanation:
Anemometer is the device used to measure wind speed in weather observations. It detects how fast air is moving by sensing the motion of the wind—often with cups that spin or a rotating vane that turns with the wind—and converts that motion into a speed reading in units like meters per second, miles per hour, or knots. Barometers track atmospheric pressure, thermometers measure temperature, and altimeters measure altitude; none of these quantify how quickly air is moving, which is why they aren’t used to measure wind speed.
