Name common meteorological instruments and their primary measurements.

• A. Thermometer
• B. Barometer
• C. Anemometer
• D. Hygrometer

Answer: (B)

Understanding what each common meteorological instrument measures helps you connect how weather data is gathered. A barometer is the instrument whose primary measurement is atmospheric pressure, a fundamental variable that changes with weather systems and helps forecasters track fronts and storm development. While other instruments are also common—thermometers measure temperature, anemometers measure wind speed, and hygrometers measure humidity—the barometer’s focus on air pressure makes it the best match for describing a key meteorological measurement.
