Geography is a difficult subject when it comes to remembering the variety of weather instruments, like instrument used to measure humidity, instrument used to measure temperature, and so on. As diverse as the weather conditions are in different places, an instrument is made to measure each factor separately. Ever wondered which instrument is used to measure wind speed on a breezy day? As you read this article, you will better understand all kinds of weather instruments. So, let’s begin!
1. List Five Weather Instruments
There are five commonly used weather instruments, which are listed below:
- Barometer: A barometer is used to measure the atmospheric pressure of an area. At mean sea level, the air pressure per square centimeter is normally close to 1.17 kg. A steady rising barometer implies good weather, while one steadily falling signals bad weather.
- Rain Gauge: A rain gauge measures the amount of precipitation. The rain gauge is a cylinder with a circular funnel attached to the top. The cylinder receives a collection of the funnel’s precipitation during rain, which is then measured using a scale imprinted on the glass.
- Aneroid Barometer: It is a device that measures air pressure without using thermometric fluids. It comprises a partially evacuated metal chamber, and changes in air pressure outside move the thin corrugated top.
- Wind Vane: It, also known as a weathercock, is a device for displaying the wind’s direction. It is employed to forecast storm severity. In disaster management, it is used to shield people from heavy winds. It is positioned at a height where a person may view how the wind can change its course.
- Wet and Dry Bulb Thermometer: Wet and dry bulb thermometers detect ambient humidity. It is an instrument used to measure humidity and temperature. Another name for it is Manson’s hygrometer. In this device, two thermometers are mounted side by side on a wooden plank. Wet-bulb readings provide the temperature of the wet air, whereas dry-bulb readings provide the temperature of the dry air. Less humidity is present when temperature differences are greater, and vice versa.
2. Which Instrument is used to Measure Wind Speed?
The wind speed is measured using an anemometer. An anemometer resembles a weather vane. But rather than using pointers to gauge wind direction, it includes four cups to precisely gauge wind speed. For meteorologists who study weather patterns, anemometers are essential tools. (See What Instrument is Used to Measure Mass of an Object?)
3. Which Scale is used to measure Wind Speed and Direction?
We now know which instrument is used to measure wind speed, the anemometer. But did you know that an anemometer can also measure wind direction? Yes, it is a common weather station instrument and can be used instead of a weathercock. Wind speed is measured using the Beaufort scale. An observation is used instead of measurement to determine it. (See What are the Properties of Air?)
4. How do you measure Wind Speed?
So, which instrument is used to measure wind speed and how? The air moves from locations of higher pressure to those of lower pressure. So, most anemometers feature four horizontal shafts organized like a wheel’s spokes. Each shaft’s end is cup-shaped and it looks like a paper fan. The anemometer spins due to the wind because the concave side of the cup is pushed by the wind more than the convex side. The greater the wind, the faster the anemometer is spinning. (See What would You expect from an Unstable Air Mass?)
5. Name the Instrument used to Measure Rainfall
A rain gauge is a tool used by meteorologists and hydrologists to collect and quantify the amount of liquid precipitation that falls over a certain area over time. It is also known as a hyetometer, an ombrometer, a pluvia metior, and a udometer. The diameter of the rain gauge’s funnel is well known. The rain that falls through this funnel is collected by the bottle positioned in the gauge. The collected water is then measured in a measuring jar. (See A Person Who studies Weather is called?)
6. Name the Unit in Which Rainfall is measured
Geologists and hydrologists commonly measure rainfall as the amount of water that could accumulate in a certain period of time in millimeters (mm).
7. What is the Instrument used for measuring Earthquake?
Seismographs are instruments that capture the surface shaking that occurs during an earthquake. The key component of a seismograph, which can be either a pendulum or a mass supported by a spring, is a seismometer. Likewise, the Mercalli and the Richter scales are also employed to gauge the direction and strength of earthquakes. (See How are Earthquakes Distributed on the Map?)
8. Name the Instrument used to measure Humidity
Hygrometers are used to measure relative humidity. A psychrometer is a simple hygrometer consisting of two thermometers. One has a dry bulb for measuring dry-bulb temperature, and the other has a wet bulb for measuring wet-bulb temperature. Moreover, a wet bulb or dry bulb thermometer is an instrument used to measure humidity. The hygrometer can also be used to measure temperature. (See What Is Humidity?)
9. Name the Unit in which Humidity is Measured
Generally, absolute humidity is measured as grams of water vapor per cubic meter of atmospheric air. The unit is grams per cube meter (g/m3).
10. Which Instrument is used to Measure Temperature?
An instrument used to measure temperature is a thermometer. It can gauge the temperatures of solids, liquids, and gases like air. Celsius, Fahrenheit, and Kelvin are the three most common temperature measuring units. Also, to know more, check out how can you measure temperature?
11. Which Instrument is used for measuring Air Pressure?
We have talked about which instrument is used to measure wind speed and about the instrument used to measure temperature too. But, with speed comes pressure. A barometer is a device that measures air pressure. The two most prevalent forms of barometers are aneroid barometers and mercury barometers. Also, to know more about it, check out what does a barometer measure?
12. What is Digital Manometer?
As you are well aware of which instrument is used to measure wind speed, you must know that a manometer is a device that measures air pressure. A digital manometer performs the same function but employs an electrical component known as a transducer. It functions similarly to a pressure sensor. An elastic part of the transducer senses pressure levels and turns this energy into an electrical signal, displaying a number on a digital display in real time. This digital manometer is designed to allow it to be used under hazardous and extreme conditions like high voltage AC lines and gas pressure lines since it doesn’t use fluids.
In addition to all the instruments we discussed in the article, there are still a few popular weather instruments. Since we didn’t talk about snow, we didn’t discuss the snow gauge. Similarly, meteorologists use lightning detectors and other amazing instruments in their daily work. As the question revolved around which instrument is used to measure wind speed, all such instruments associated with wind and air have been covered. (Also read How Is Energy Measured?)
