Will not the clouds be clouded over the sky, which will eventually lead to a prolonged rainstorm 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 aboutthe existence of an instrument such as a barometer. What is it for? To measure the pressure in the atmosphere. Based on this, you can predict the weather. Certainly, a barometer is a useful thing.
Any person, directly or indirectly,is influenced by atmospheric pressure, because it is located 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 the mercury column will always be determined by the device we are considering.
The barometer is an indispensable thing for those whospend most of his 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 terms. However, many people, as before, prefer to acquire their own home weather station. In addition, the barometer is also a practical thing, as portable models are now in high demand, which are convenient to carry.
Types of appliances for home use
Usually everyone uses at homebarometer-aneroid, 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 quantity is used to change the shape of the home meteorological 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 we 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, evendvoechniki 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.</ p>
