Normal atmospheric pressure in Moscow: what does it depend on?

As in other places, in the capital of Russia, the well-being of people directly depends on what is the normal atmospheric pressure in Moscow. It consists of several components. This geographical latitude, the height of the settlement above sea level, air temperature and so on.

In addition, the importance with which the atmosphere is pressing on people is very unstable and changes even during the day. Therefore, it is better for weatherwomen to know in advance what to expect from the weather in order to be able to prepare.

What is atmospheric pressure and what is normal?

Before talking about what normal atmospheric pressure in Moscow, you need to understand what it is. So, about everything in order.

The pressure of the atmosphere is determined by the weight of the air. Its value is determined from the calculation of 1 cm ^{2 of the} area of the body located on the surface of the Earth. The pressure is measured in several units: from millibars (mb) to millimeters of mercury (mm Hg) and Pascals (Pa). In different situations, they use what is more convenient. In meteorology, millimeters of the mercury column took root.

Normal is the value at sea level, that is, at an altitude of 0 m, at a temperature of 0 ° C. It was equal to 760 mm Hg. Art.

However, such a number is not always normal. Atmospheric pressure in Moscow, for example, is much lower than this value. And even within the boundaries of the city, it can differ substantially.

The air presses on people. Why do not they feel it?

If you translate into a simple language, it turns out that the human body is pressured by air, whose weight is 15 tons. Agree, this is a lot.

The pressure of the atmosphere is not felt, because it is balanced by the presence of dissolved gases in the blood. They allow people to ignore a huge column of air above them.

The human body has adapted, and normal atmospheric pressure in Moscow does not have a negative impact on his well-being. If you train for a long time, you can normally exist at a lowered or increased value of mm of mercury.

How does the air pressure depend on the height?

It decreases. Because of the uneven density of gases, it varies unequally. So, when you lift the first 50 meters, the pressure will be 5 mm Hg. Art. less. Another 50 m up - and a decrease of another 4 mm Hg. Art.

Due to the fact that the capital of Russia is at an altitude of 130-150 m above the sea surface, the normal atmospheric pressure in Moscow will be 746-749 mm Hg. Art. The unevenness of the relief of the city does not allow to give an unambiguous result. So, the answer to the actual question: "Normal atmospheric pressure in Moscow is how much?" - will be vague.

If you climb the Ostankino TV Tower, you will be at an altitude of 540 m. Atmospheric pressure here will be about 711 mm Hg. Art. Therefore, a rapid rise to it is not recommended because of the possibility of deterioration of well-being.

Fluctuation of atmospheric pressure depending on time of day and season

It is determined by the temperature of the air - at night it is lower than in the daytime. In direct dependence on temperature there is also pressure. This is normal. Atmospheric pressure in Moscow during the day, too, will change, but not much. Usually such a fluctuation does not exceed 2 mm of mercury, which fits within the acceptable limits.

The same can be said about the seasonal pressure change. With an increase in the average daily temperature in spring and summer, its growth is noted. Therefore, normal atmospheric pressure in Moscow in winter will be slightly lower than in summer.

Relation of atmospheric pressure with weather

In the air, regions with increased or decreased pressure are constantly formed . In meteorology, they are called anticyclones and cyclones, respectively. They slowly move along the surface of the Earth and bring with them a changed pressure. If its value is significantly different from the usual, the locals can react poorly to this. Because the differences are fixed in the range from 640 to 815 mm Hg. Art.

How does the human body react to pressure fluctuations?

It all depends on how much it is adapted to change. Medical workers believe that the value equal to 750-765 mm Hg. This is normal atmospheric pressure in Moscow. Now the living conditions of residents of megacities are such that they are forced to live in high-rise buildings, and work or at least get to the place of service - at ground level. Therefore, people for a day experience pressure fluctuations. So the body gets used to and becomes less susceptible to smooth changes. This is a good workout.

Another thing is if the atmospheric pressure changes sharply in one direction or another. This jump is the drop or rise of the value by 1 mm in 3 hours. Then the cardiovascular system is under severe stress.

If the pressure drops, then:

• A person experiences headaches and difficulty breathing;

• The beat of his heart increases, because in the blood there is a lack of oxygen;

• He has numbness of fingers and joint pains appear - this is due to poor blood supply.

In case of pressure increase:

• Blood is supplied with a lot of oxygen, this leads to an increase in the tone of the vessels and the appearance of spasms;

• A person notices the appearance of flies in the eyes, dizziness and nausea.

Results: recommendations for those who are sensitive to changes in atmospheric pressure

If a weather forecast has been sounded in the weather forecast, there will be a pressure jump. This is a signal to the maximum to reduce the load on the body on this day. Such a measure would be enough to not inconvenience.

In situations where a person is prone to increase or decrease blood pressure, it is worth consulting with a doctor and picking up medication.
