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 is made up of several components. This is the geographical latitude, the height of the settlement above sea level, air temperature and so on.

Besides, the value with which the atmosphere presses on people is very unstable and changes even during the day. Therefore, it is better for weather dependent people 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 is in Moscow, you need to understand what it is. So, first things first.

The pressure of the atmosphere is due to the weight of the air. Its value is determined based on 1 cm² of the area of the body located on the surface of the Earth. Pressure is measured in several units: from millibars (mb) to millimetersmercury column (mm Hg) and Pascals (Pa). In different situations, use what is more convenient. In meteorology, millimeters of a column of mercury have taken root.

Normal is the value at sea level, that is, at an altitude of 0 m, at a temperature of 0 ºС. It turned out to be equal to 760 mm Hg. st.

However, this 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 vary significantly.

The air presses on people. Why don't they feel it?

If translated into simple language, it turns out that air weighing 15 tons presses on the human body. Agree, this is a lot.

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

The human body has adapted, and the normal atmospheric pressure in Moscow does not adversely affect its well-being. If you train for a long time, then you can normally exist with a low or high value of mmHg.

How does air pressure vary with altitude?

It's shrinking. Due to the uneven density of gases, it varies unequally. So, when you rise to a height of the first 50 meters, the pressure will become 5 mm Hg. Art. smaller. Another 50 m up - and a decrease of another 4 mm Hg. st.

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

If you climb the Ostankino TV tower, you will find yourself at an altitude of 540 m. Atmospheric pressure here will be about 711 mm Hg. Art. Therefore, a quick ascent to it is not recommended due to the possibility of a deterioration in well-being.

Atmospheric pressure fluctuations depending on time of day and season

It is determined by the air temperature - at night it is lower than during the day. Pressure is also directly related to temperature. This is fine. Atmospheric pressure in Moscow during the day will also change, but not much. Typically, this fluctuation does not exceed 2 mmHg, which is within the acceptable range.

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

Relationship between atmospheric pressure and weather

Areas of high or low pressure are constantly formed in the air. In meteorology, they are called anticyclones and cyclones, respectively. They slowly move along the surface of the Earth and bring with them a change in pressure. If its value is significantly different from the usual, then local residents may react poorly to this. Because the differences are fixed inboundaries from 640 to 815 mm Hg. st.

How does the human body react to pressure fluctuations?

It all depends on how adaptable he is to change. Medical professionals believe that a value of 750-765 mm Hg. Art., is the 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 their place of service, at ground level. Therefore, people experience fluctuations in pressure within one day. So the body gets used to and becomes less receptive to smooth changes. It's a good workout.

It's another matter if atmospheric pressure changes sharply in one direction or another. Such a jump is a drop or rise in a value of 1 mm in 3 hours. Then the cardiovascular system is under serious stress.

If the pressure goes down, then:

• person experiencing headaches and difficulty breathing;
• his heartbeat increases as there is a lack of oxygen in his blood;

• he gets numbness in his fingers and pain in his joints due to poor blood supply.

  

In case of increased pressure:

• blood is supplied with more oxygen, which leads to increased vascular tone and spasms;
• a person notes the appearance of flies in the eyes,dizziness and nausea.

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

If the weather forecast warns of a sharp change in the weather, then there will be a pressure surge. This is a signal to reduce the load on the body as much as possible on this day. Such a measure would be enough to avoid inconvenience.

In situations where a person is prone to high or low blood pressure, it is worth consulting with your doctor and choosing medication.
