On Friday, May 20, the capital region will be almost in the center of a young cyclone, Gazeta.Ru was told in center "Phobos". The cyclone will bring dense cloud fields and intense rain to Moscow. Even if weather forecasters, who are usually cautious in their wording, use the term “intense” and generally announce an orange level of danger due to showers, it means that

not streams will run along the asphalt, but Niagara Falls.

clouds, heavy rains in the daytime and the wind of the eastern quarter (5-10 m/s) will limit the heating of the air. +9…+14°С is expected at night, +12…+17°С during the day. The atmospheric background is low, 736 mm Hg. Art.

On Saturday, the heavenly office will turn on the tap, the intensity of the rain will decrease significantly, but the temperature will also go down. At night on May 21 it will be +6…+11°С, in the daytime +11…+16°С. Wind south, southwest, 5-10 m/s. Keep this in mind if you are going to one of the events as part of the Night of Museums campaign. In the most popular galleries and exhibition halls, there can be so many people that you will have to wait in the street for your turn.

We advise you to use mobile application Meanwhile, which will display the workload of museums in real time and help plan a cultural trip. The pressure on this day will rise slightly and will be 741 mm Hg. Art.

On the night of Sunday, May 22, the so-called flower full moon will take place. According to the Moscow Planetarium, it is customary to call the fifth full moon of the year this way, because it is at this time that the lush flowering of nature is observed.

Muscovites will be able to enjoy the view of the Earth’s satellite and the aromas of lilacs, but in brief moments when the cloudy sky clears up and another rain ends. It is this kind of weather, with a temperature of +5 ... + 10 ° С, that is expected at night. During the day, due to the departure of the cyclone and the arrival of warm air masses, the air will warm up to + 13 ... + 18 ° С. Wind northwest, 4-9 m/s. The pressure is still not up to the norm - 742 mm Hg. Art.

On Monday, May 23, cyclonic weather will continue in Moscow. Partly cloudy with some showers again. It's time to make a wise investment for the coming months and bring a spare pair of dry shoes or an extra umbrella to work.

The warming trend that emerged the day before will continue, forecasters say. But

not that the temperature increase was significant: at night it is still +5…+10°С, in the daytime +14…+19°С.

Wind northwest, 4-9 m/s. The atmospheric background is gradually approaching normal values ​​- 743 mm Hg. Art.

On May 24, the synoptic situation in Moscow will not change significantly: heating and in some places hot water turned off and, apparently, the sun too. Lots of clouds and rain again. Air temperature at night +7…+12°С, in the afternoon on Tuesday +16…+21°С. Wind southeast, 4-9 m/s. The pressure will rise to almost the reference 745 mm Hg. Art.

On Wednesday, May 25, with an increase in atmospheric pressure in the capital region, the weather will clear up for a short time and become warmer. Night temperature +7…+12°С and daytime temperature within +18…+23°С is a good gift for Moscow graduates, for whom the last school bell will ring that day. But, as if symbolizing the inexorably approaching exam, on this day there will be short-term rains in some places. We hope that neither the clouds nor the wind of the eastern quarter (3-8 m/s) will spoil the impression of the holiday. The atmospheric background is normal - 746 mm Hg. Art.

On Thursday night, thickening the clouds and bringing new portions of rain, to the capital with southeast wind up to 10 m / s, a cyclone will come. But it will not stay in the region for a long time and by the evening of May 26 it will go north, so it will clear up in Moscow. Cloudy, partly cloudy in the evening, however, at night and during the day it will still rain of varying duration and intensity. Girls with curly hair, accept that on this day your hairstyle, despite all the curling irons and straighteners, will most likely resemble a dandelion.

The air temperature at night is +10…+15°С, during the day +18…+23°С. Atmospheric pressure will drop slightly and will be 744 mm Hg. Art.

Friday, May 27 Atmosphere pressure in the capital region will continue to rise and reach 747 mm Hg. Art. But ruling in Moscow air masses will be in an unstable state, which will cause short rains during the daytime hours.

However, we will survive this trouble, because summer heat will come to the city.

The air temperature at night is +9…+14°С, in the daytime +19…+24°С. Wind southeast, 2-7 m/s. If there are no urgent matters for the next day, then this Friday is the time for romantic night walks and dawn meetings, for example, on the embankment of the Moscow River or the Yauza.

During the last weekend of May, the nature of the weather will not change significantly. Saturday and Sunday will be marked by variable cloudiness and intermittent rains, which, according to the law of meanness, will take place mainly during daylight hours.

All weekend night temperatures will fluctuate from +10°С to +15°С, and daytime temperatures will range from +20°С to +25°С. On Saturday, May 28, the wind of the eastern quarter, 2-7 m/s, and on Sunday, May 29, the western quarter, the speed is the same. The pressure both days will be kept at the same, normal level - 746 mm Hg. Art.

The sun is the source of life on the planet. Its rays give the necessary light and warmth. At the same time, ultraviolet radiation from the Sun is detrimental to all living things. To find a compromise between useful and harmful properties Sun, meteorologists calculate the index of ultraviolet radiation, which characterizes the degree of its danger.

What UV radiation from the sun is

The ultraviolet radiation of the Sun has a wide range and is divided into three regions, two of which reach the Earth.

  • UV-A. Longwave radiation range
    315–400 nm

    The rays pass almost freely through all atmospheric "barriers" and reach the Earth.

  • UVB. Medium wave radiation range
    280–315 nm

    The rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.

  • UVC. Shortwave radiation range
    100–280 nm

    The most dangerous area. They are completely absorbed by stratospheric ozone without reaching the Earth.

The more ozone, clouds and aerosols in the atmosphere, the less the harmful effect of the Sun. However, these saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in spring, and the minimum - in autumn. Cloud cover is one of the most variable weather characteristics. The content of carbon dioxide also changes all the time.

At what values ​​of the UV index is there a danger

The UV index gives an estimate of the amount of UV radiation from the Sun on the Earth's surface. UV index values ​​range from safe 0 to extreme 11+.

  • 0–2 Low
  • 3–5 Moderate
  • 6–7 High
  • 8–10 Very high
  • 11+ Extreme

In mid-latitudes, the UV index approaches unsafe values ​​(6–7) only at the maximum height of the Sun above the horizon (occurs in late June - early July). At the equator, during the year, the UV index reaches 9...11+ points.

What is the benefit of the sun

In small doses, UV radiation from the Sun is essential. The sun's rays synthesize melanin, serotonin, vitamin D, necessary for our health, and prevent rickets.

Melanin creates a kind of protective barrier for skin cells from the harmful effects of the sun. Because of it, our skin darkens and becomes more elastic.

Happiness hormone serotonin affects our well-being: it improves mood and increases overall vitality.

Vitamin D strengthens the immune system, stabilizes blood pressure and performs anti-rickets functions.

Why is the sun dangerous?

When sunbathing, it is important to understand that the line between beneficial and harmful Sun is very thin. Excessive sunburn always borders on a burn. UV radiation damages DNA in skin cells.

The body's defense system cannot cope with such an aggressive impact. This lowers the immune system, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet destroys the DNA chain

How does the sun affect people?

Susceptibility to UV radiation depends on skin type. The most sensitive to the Sun are people of the European race - for them, protection is required already at an index of 3, and 6 is considered dangerous.

At the same time, for Indonesians and African Americans, this threshold is 6 and 8, respectively.

Who is affected the most by the Sun?

    people with light
    skin tone

    People with many moles

    Residents of the middle latitudes while relaxing in the south

    winter lovers
    fishing

    Skiers and climbers

    People who have family history skin cancer

In what weather is the sun most dangerous

The fact that the Sun is dangerous only in hot and clear weather is a common misconception. You can also get burned in cool cloudy weather.

Cloudiness, no matter how dense it may be, does not at all reduce the amount of ultraviolet to zero. In mid-latitudes, cloudiness significantly reduces the risk of sunburn, which cannot be said about traditional places. beach holiday. For example, in the tropics, if in sunny weather you can get burned in 30 minutes, then in cloudy weather - in a couple of hours.

How to protect yourself from the sun

To protect yourself from harmful rays, follow these simple rules:

    Get less exposure to the Sun during the midday hours

    Wear light-colored clothing, including wide-brimmed hats

    Use protective creams

    Wear sunglasses

    Stay in the shade more on the beach

Which sunscreen to choose

Sunscreen differs in the degree of protection from the Sun and is marked from 2 to 50+. The numbers represent the share solar radiation, which overcomes the protection of the cream and reaches the skin.

For example, when applying a cream labeled 15, only 1/15 (or 7%) of the UV rays will penetrate the protective film. In the case of cream 50, only 1/50, or 2%, affects the skin.

Sunscreen creates a reflective layer on the body. However, it is important to understand that no cream is capable of reflecting 100% of ultraviolet radiation.

For everyday use, when the time spent under the Sun does not exceed half an hour, a cream with protection 15 is quite suitable. For tanning on the beach, it is better to take 30 and above. However, for fair-skinned people, it is recommended to use a cream labeled 50+.

How to apply sunscreen

The cream should be applied evenly to all exposed skin, including the face, ears and neck. If you plan to sunbathe for a long time, then the cream should be applied twice: 30 minutes before going out and, additionally, before going to the beach.

Please refer to the cream instructions for how much to apply.

How to apply sunscreen while swimming

Sunscreen should be applied every time after bathing. Water washes away the protective film and, reflecting the sun's rays, increases the dose of ultraviolet radiation received. Thus, when bathing, the risk of burning increases. However, due to the cooling effect, you may not feel the burn.

Excessive sweating and rubbing with a towel is also a reason to re-protect the skin.

It should be remembered that on the beach, even under an umbrella, the shade does not provide full protection. Sand, water, and even grass reflect up to 20% of UV rays, increasing their impact on the skin.

How to protect your eyes

sunlight, reflected from water, snow or sand, can cause a painful burn of the retina. Use sunglasses with an ultraviolet filter to protect your eyes.

Danger for skiers and climbers

In the mountains, the atmospheric "filter" is thinner. For every 100 meters of altitude, the UV index increases by 5%.

Snow reflects up to 85% of UV rays. In addition, up to 80% of the ultraviolet reflected by the snow cover is again reflected by the clouds.

Thus, in the mountains, the Sun is most dangerous. Protect your face lower part chin and ears are necessary even in cloudy weather.

How to deal with sunburn if you are burned

    Treat the body with a damp sponge to wet the burn

    Lubricate the burnt areas with anti-burn cream

    If the temperature rises, consult a doctor, you may be advised to take an antipyretic

    If the burn is severe (skin is very swollen and blisters), seek medical attention.

The heat is gradually leaving the center of the European part of Russia. From August 23 in the west and southwest of the Central federal district its influence will be spread by a cold atmospheric front, which will come along with the North Atlantic cyclone. It will not bypass the capital region either: a gradual cooling will begin in Moscow and the Moscow region. A short heat will be replaced by rain and thunderstorms. This is reported by the Hydrometeorological Center of Russia.

"In the metropolitan area<…>On Wednesday, August 23, cloudy weather is expected. At night, intermittent rain, thunderstorms<…>. Rain during the day, heavy in some places, in some areas - thunderstorm, hail, ”the center’s website says.

By Friday, the night temperature will drop to +10 - +12 °С, daytime - to +16 - +18 °С. Wind gusts in places will reach 12-17 meters per second.

Forecasters have warned of a "yellow" level of weather danger in the capital. At the same time, as Yevgeny Tishkovets, a leading employee of the Phobos weather center, said earlier, the cooling in the region is quite consistent with the temperature norm.

“In fact, we will just return to the climate norm. But after +30, the cold snap will, of course, be felt. We will feel the breath of the approaching autumn,” he explained.

The chief specialist of the Moscow Meteorological Bureau Tatyana Pozdnyakova, in an interview with RT, explained that so far the anticyclone determines the weather in the capital.

“It goes to the southeast, atmospheric pressure will decrease. From the south, as if towards the cyclone, which is now located over St. Petersburg, the cyclone will also move, and they will be connected by an atmospheric front. It is with this atmospheric front that changes in the weather will be associated. Although the center of this southern cyclone will for the time being pass through the west of European Russia, that is, far from Moscow, nevertheless, this will affect the atmospheric front of the capital, ”Pozdnyakova commented on the change in weather.

According to her forecasts, showers, which may be accompanied by thunderstorms and increased winds, will cover Moscow on the evening of August 23. “The first portion of bad weather awaits the capital on Wednesday after 18:00. Since the atmospheric front will approach us during the greatest warming of the air, the development of powerful cumulus clouds is possible, which means that there are all the prerequisites for thunderstorms, hail, and squally wind amplifications, ”the specialist clarified.

autumn hints

Pozdnyakova emphasized that rainy weather with varying intensity of precipitation will be established in the capital starting from Thursday, August 24. At the same time, the air temperature will also decrease.

“On Thursday, we will be in the zone of this for almost the whole day. atmospheric front. After its passage, a gradual decrease in temperature will begin. First, in the daytime in Moscow it will be somewhere +23 - +25, then even colder. If now the air temperature in the capital region is 6-7 degrees above the climatic norm, then in the coming days it will gradually approach the norm. And on weekends, most likely, the temperature will be below the climatic norm, at night - by as much as 10 degrees, ”said an employee of the Moscow Meteorological Bureau.

In the future, according to her, temperature fluctuations during the day will become even more noticeable. “It will remind you of autumn. The days are getting shorter, and the nights are getting longer and colder," Pozdnyakova said.

Waiting for Indian summer

Forecasters believe that in September the heat will return and Muscovites can count on Indian summer.

“Specialists of long-term forecasting believe that September will be quite warm: the air temperature in early autumn will be at +20 - +25 degrees,” the meteorologist says.

It should be noted that this year summer months did not spoil Moscow warm weather: The capital survived a powerful hurricane and a record downpour. On June 30, more than half of the monthly rate precipitation (86%). June 2017 was the coldest for Moscow over the past 14 years - weather forecasters recorded frosts down to -1 ° C.
