And will not the sky be clouded up by the clouds, which in the end will lead to a prolonged downpour with a thunderstorm?

Perhaps the rain will be accompanied by hail? As you can see, there are a lot of questions about the weather.

To have a barometer is simply necessary

It is in order to make them smaller, and metrology specialists work: they are constantly engaged in the modernization of weather-oriented devices and devices.

And, of course, almost everyone knows about the existence of such a device as a barometer. What is it for? To measure the pressure in the atmosphere. Based on this, you can predict the weather. Of course, a barometer is a useful thing.

Any person, directly or indirectly, experiences the influence of atmospheric pressure, because it is on the surface of the Earth. A huge number of people complain of headaches during periods of abrupt change of the above parameter.

Advantages of a home weather station

The exact figure in millimeters of mercury will always be determined by the device we are considering.

The barometer is an indispensable thing for those who spend most of their time on the backyard. Why? For proper planting of some plants, it is very important to know the specific value of the pressure in the atmosphere.

Many can say: "Of course, a barometer is a necessary device, but there is television and the Internet." Well, the age of high technology dictates its conditions. However, many people, as before, prefer to acquire their own home weather station. In addition, the barometer is also a practical thing, since portable models are now in high demand, which are convenient to carry.

Types of appliances for home use

Usually, everyone uses an aneroid barometer at home without mercury. It is completely harmless to human health in case of damage. Such a device is made in the form of a small corrugated box, from which "excess" air is expelled, and the necessary amount is used to change the shape of the home weather station. As soon as the pressure level in the atmosphere changes, the box either expands or contracts.

Forecasts of such models of meteorological stations are very accurate.

There are also mercury devices.

"Why do you need a barometer of this type?" - you can 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 deflated. The tube is installed directly above the reservoir, which contains mercury. When the level of atmospheric pressure changes, the mercury volume in the column also becomes smaller or larger.

So, after reading this article even the dvoechniki can now answer the question about what the barometer measures. If you want to be the first to know about the smallest changes in the weather, get this very useful device.
