5 Ways Weather Instruments Can Help You

[ad_1]

Looking for the perfect weather instrument that can help you know how the climate would be? No, you do not need to look out for the news channel updates any more. Instead, you can check out how the day would be on your own.

What are these instruments?

As the name suggests, weather instruments help in weather forecast and tell us the kind of weather we are going to experience in the next few days. They can prove to be quite helpful in various ways, some of which have been mentioned below. Each of these instruments has been improvised on over the years and offer accurate and perfect readings in today’s time.

1. Measure the current temperature

Weather instruments help to measure and record both low and high daily temperatures with the help of an electronic sensor. The measurement is done in degrees Fahrenheit and degrees Celsius and the temperature can be recorded as many times as need be. In the olden days, liquid-in-glass thermometers were used but with advancement in technology electronic sensor systems became common.

2. What’s the atmospheric pressure?

Another way in which such instruments help us is by measuring the atmospheric pressure in a measurement known as millibars. Low and falling pressure generally indicates rain while a sunny weather is indicated by a rising and high pressure. Such an instrument can also measure the air pressure.

3. What’s the speed of the wind?

Weather instruments are also useful in measuring the speed of wind in miles per hour along with its direction. 3 cups are fixed to a mobile shaft and the cups spin faster when fast winds blow. The dial shows the wind’s actual speed. Many other devices use a propeller instead of cups to achieve the same measurement. A wind vane helps to measure the wind’s direction at any given point of time.

4. What’s the humidity level?

Such instruments also help measure humidity in degrees Celsius and degrees Fahrenheit. A sling psychrometer makes use of a dry and a wet bulb thermometer and measures the air’s relative humidity. Other devices use a sheaf of hair which increases in length as there is an increase in relative humidity.

5. What is the amount of hailstorm?

Weather instruments are extremely helpful in measuring the intensity of a hailstorm. You will find an aluminium foil and a florist’s foam in a standard instrument. The hail that falls, strikes the foil creating dimples which can be measured by the observer once the storm is over.
