Surely there are few people who do not show interest in whether today will be cloudy or sunny. As a rule, when going outside, we try to look at the sky to try to visually determine whether it will rain today or whether the sun will shine. Should I take an umbrella or not? Will clouds cloud the sky, which will eventually lead to a prolonged downpour with a thunderstorm?
Maybe the rain will be accompanied by hail? As you can see, there are a lot of questions about the weather.
Having a barometer is a must
Metrology specialists work precisely to reduce their number: they are constantly busy upgrading devices and instruments focused on weather prediction.
And, of course, almost everyone knows about the existence of such a device as a barometer. What is it for? For measuring pressure in the atmosphere. Based on this, the weather can be predicted. Of course, the barometer is a useful thing.
Any person, directly or indirectly, is affected by atmospheric pressure because he is on the surfaceEarth. A huge number of people complain of headaches during periods of a sharp change in the above parameter.
The benefits of a home weather station
The exact figure in millimeters of mercury will always be determined by the device we are considering.
A barometer is an indispensable thing for those who spend most of their time in the garden. Why? Knowing the specific pressure in the atmosphere is very important for proper planting of some plants.
Many people may say: "Of course, a barometer is a necessary device, but there is television and the Internet." Well, the age of high technology dictates its own conditions. However, many people, as before, prefer to acquire their own home weather station. In addition, the barometer is also practical, as portable models that are convenient to carry are in high demand today.
Types of appliances for home use
Usually everyone uses an aneroid barometer at home, without mercury. It is completely harmless to human he alth in case of damage. Such a device is made in the form of a small-sized corrugated box, from which excess air is “expelled”, and the required amount is used to change the shape of a home weather station. As soon as there is a change in the level of pressure in the atmosphere, the box either expands or contracts.
Forecasts of such models of weather stations are extremely accurate.
There are also mercury appliances.
"What is this type of barometer for?" you might ask. They are also designed to predict the weather. They are made in the form of a tube of glass, from which the air is pumped out. The tube is installed directly above the tank containing mercury. When the atmospheric pressure level changes, the volume of mercury in the column also becomes smaller or larger.
So, after reading this article, even losers will now be able to answer the question of what the barometer measures. If you want to be the first to know about the slightest changes in the weather, get yourself this most useful device.
