As in other places, in the Russian capital, the well-being of people directly depends on how normal atmospheric pressure in Moscow is. It consists of several components. This is the geographical latitude, the height of the settlement above sea level, air temperature and so on.
In addition, the importance with which the atmosphere puts pressure on people is very unstable and changes even during the day. Therefore, it is better for weather addicts to know in advance what to expect from the weather in order to be able to prepare.
What is atmospheric pressure and which is normal?
Before talking about what normal atmospheric pressure is in Moscow, you need to understand what it is. So, first things first.
Atmospheric pressure is determined by the weight of the air. Its value is determined based on 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 (mmHg) and Pascals (Pa). In different situations, they use what is more convenient. In meteorology, millimeters of a mercury column have taken root.
The normal value is considered at sea level, that is, at an altitude of 0 m, at a temperature of 0 º. It turned out to be equal to 760 mm RT. Art.
However, this number is not always normal. Atmospheric pressure in Moscow, for example, is much lower than this value. And even within the city, it can vary significantly.
Air presses on people. Why don't they feel it?
If translated into simple language, it turns out that air weighs 15 tons weighs on the human body. Agree, this is a lot.
Atmospheric pressure is not felt, because it is balanced by the presence of gases dissolved in the blood. They allow people to not notice the huge column of air above them.
The human body has adapted, and normal atmospheric pressure in Moscow does not adversely affect his well-being. If you train for a long time, then you can normally exist with a reduced or increased value of mmHg.
How does air pressure depend on altitude?
It is decreasing. Due to the uneven density of gases, it varies unequally. So, when raised to a height of the first 50 meters, the pressure will become 5 mmHg. Art. smaller. Another 50 m up - and a decrease of another 4 mm Hg. Art.
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 Moscow will be equal to 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 urgent question: “How much is normal atmospheric pressure in Moscow?” - 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 climb to it is not recommended because of the possibility of deterioration.
Variations in atmospheric pressure depending on the time of day and season
It is determined by the air temperature - at night it is lower than during the day. Direct pressure depends on temperature. This is normal. The atmospheric pressure in Moscow during the day will also vary, but not much. Typically, such an oscillation does not exceed 2 mmHg, which fits within the acceptable range.
The same can be said about the seasonal change in pressure. With increasing 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.
The relationship of atmospheric pressure with the weather
Areas with increased or decreased pressure are constantly formed in the air . In meteorology, they are called anticyclones and cyclones, respectively. They move slowly along the surface of the Earth and bring with them altered pressure. If its value differs significantly from the usual, then local residents may react poorly to this. Because the differences are recorded in the range from 640 to 815 mm RT. Art.
How does the human body respond to pressure fluctuations?
It all depends on how adaptable it is to change. Medical professionals believe that a value of 750-765 mm Hg. Art. is normal atmospheric pressure in Moscow. Now the living conditions of residents of megacities are such that they are forced to dwell in high-rise buildings, and work, or at least get to the duty station, at ground level. Therefore, people experience pressure fluctuations within one day. So the body gets used and becomes unresponsive to smooth changes. This is a good workout.
Another thing is if the atmospheric pressure sharply changes in one direction or another. Such a jump is a drop or rise in the value of 1 mm in 3 hours. Then the cardiovascular system experiences a serious load.
If the pressure drops, then:
a person experiences headaches and shortness of breath;
the beating of his heart increases, as a lack of oxygen is detected in the blood;
he has numbness in his fingers and pains in his joints - this is due to poor blood supply.
In case of pressure increase:
blood is supplied with a large amount of oxygen, this leads to an increase in vascular tone and spasms;
a person notes the appearance of flies in the eyes, dizziness and nausea.
Summary: recommendations for those who are sensitive to changes in atmospheric pressure
If a warning about a sharp change in the weather was sounded in the weather forecast, then there will be a jump in pressure. This is a signal to reduce the burden on the body as much as possible on this day. Such a measure will be quite enough so as not to inconvenience.
In situations where a person is inclined to increase or decrease blood pressure, it is worthwhile to consult with your doctor and choose a medication.
