Some of the instruments used by meteorologists to study weather are:
1. Thermometer - this instrument measures the temperature of the air
2. Barometer - measures atmospheric pressure
3. Anemometer - measures the speed of the wind. Some anemometers also measure the direction of the wind.
4. Hygrometer - measures relative humidity (the amount of moisture in the air).
