1. How do meteorologists make weather observations? Measuring the Weather

2. 1. Thermometer An instrument for measuring temperature, especially one having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.

3. 2. Barometer An instrument for measuring atmospheric pressure, used especially in weather forecasting.

4. 3. Rain Gauge Any instrument designed to measure rain amount.

5. 4. Anemometer An instrument for measuring and recording the speed of the wind

6. 5. Radiosonde A miniature radio carried aloft by an unmanned balloon to broadcast the pressure, temperature, and relative humidity of the upper air and to automatically transmit that information to the ground.

7. 6. Weather Satellite A satellite that orbits Earth taking pictures, for example monitoring the temperature and measuring the height of waves.

8. 7. Doppler Radar A special kind of radar system that measures the distance and direction of rain.

9. 8. Observations Eyes, ears, and smell are probably the most accurate tools. Observing the clouds, precipitation, and color of the sky.
