Question

Identify four instruments used by meteorologists to study weather. Be sure to describe what type of information each one measures.

Answer 1

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).

Answer 2

Answer:

Meteorologists use thermometers to measure temperature, or how hot or cold the atmosphere is at a given place and time. A barometer is used to measure air pressure to watch for changes in pressure levels, which usually indicate that a change in weather is coming. Precipitation, such as rain or snow, is measured using a rain gauge. The gauge helps to determine how much precipitation fell over a given period of time. The most sophisticated instrument used by meteorologists is a weather satellite. A satellite orbits the Earth and collects data about the Earth’s atmosphere, such as the temperature or humidity of an area. They are very useful for tracking the movement of storms so that severe weather warnings can be issued to the public.
