The unique city of Sochi, where there is no winter, but dark nights. Why does it get dark quickly in the south? Why are the nights dark in the south
The most popular city in Russia now is Sochi. It became the only southern capital of the Winter Olympics. But this is not only its uniqueness. Still there is snow, but there is no winter. There are built indestructible houses that live for thousands of years. And even in how he has changed, he now also has no equal.
Why is there snow in Sochi, but not in winter
The main feature of Sochi is its unique climate. Dense green forests of the middle zone are concentrated on one territory, the exotic of the world's northernmost subtropics - the never-freezing Black Sea and the Caucasus Range, which protects from cold winds. That is why the average monthly air temperature is always above zero. And the division into four seasons is conditional.
Sochi residents, in fact, live in two seasons. Cold (if I may say so), when it is windy, overcast and rainy. And warm when it's dry and clear outside and sea breezes blow. And although snow stays on the peaks of the Caucasus Mountains all year round, there is virtually no real winter in this city. By the way, they say that one of the reasons why Sochi was nominated as the capital of the XXII Winter Olympic Games was the absence of Russian frosts, which foreigners are so afraid of.
Black Sea nowOn the Internet, you can watch the Sochi coast in real time. There is a webcam on the site sochiadm.ru in the "About the city" section.On the occasion of the Sochi Olympics, a hundred-ruble commemorative banknote was issued. On its front side, seemingly incompatible (but not in the case of Sochi) natural beauties echo - the snowy peaks of the Caucasus and the Black Sea coast. Here, too, it was not without uniqueness - the Sochi banknote has a vertical image, this has never happened in Russia.
The back of the banknote depicts the now world-famous Fisht stadium.
Olympic hundred100 rubles is the only Russian banknote with a vertical image. Sold a circulation of 20 million copies.
Fisht is translated from Adyghe as "white head". The stadium received this name from the mountain peak of the same name in the Caucasus. The general plan of the stadium resembles the images of a shell and a snowy peak at the same time. Although it was originally planned to be built in the shape of a Faberge Easter egg.
Now "Fisht" is under reconstruction and will receive guests only in 2018 - at the next World Cup. The event for Russia is also unique - for the first time the world championship will be held in our country, including at the Sochi sports ground.
In general, in preparation for the Winter Games in Sochi, more than 360 kilometers of roads and over 200 kilometers of railways were laid, 22 tunnels were built, a new airport, 60 sports facilities, among them the Iceberg Ice Palace, the Shayba arena, and the skating center. Adler-Arena”, a huge number of hotels. No other Russian city compares to Sochi in terms of such rapid reconstruction.
At the same time, there are many architectural, historical and natural attractions in Sochi: waterfalls, gorges, caves, lakes, an arboretum, a yew-boxwood grove with thousand-year-old trees. But the most mysterious are the stone dolmens of the Bronze Age. These are some houses built of large stone slabs with holes (manholes) on the facade, which are closed with a stone cork. There are quite a few varieties.
Fisht Stadium 40,000 spectators accommodated the stadium "Fisht" at the Olympics. By the 2018 FIFA World Cup, the capacity will be increased to 45,000 people.
Why you need to know the buyback to live in Sochi
Now there are heated debates about making a gambling zone in Sochi. But did you know that the expression, which has already become a proverb - "if I knew the buyback, I would live in Sochi" - came out of the criminal world and described the city as a place of the most inventive card cheats. Sochi katals skillfully devastated the wallets of gullible tourists on trains on the way to the resort, at the station and on the beaches. But the really big scams took place in respectable hotels, where cheaters, after several games of preference, pulled mind-boggling sums from underground Soviet millionaires. The guests did not have a chance to win back: the marked decks, sealed in the factory packaging, went straight to the city's kiosks. And cheaters, without risking anything, always received the “correct” cards, that is, they “knew the buy-in”. Every petty thief dreamed of the luck of the Sochi gamblers, who lived on a grand scale by the standards of the USSR. And later they began to sing about the purchase.
Why are dark nights in Sochi
The phrase “dark nights in the city of Sochi” has long become a catchphrase, but not every one of us knows why they say so. In fact, the veracity of this expression can not be questioned. Nights in Sochi are really blacker than darkness.
In summer, in the north of Russia, the period of white nights begins, when the sun sets for only a few hours. And in the south, at the same time, the opposite is happening - black nights. Due to the tilt of the earth's axis, the sun sets very deep below the horizon, as a result, the length of the daylight hours is almost equal to the length of the dark time of the day. And the closer to the equator, the stronger this equality. Therefore, it gets dark early in Sochi, the sky is deep black, and the stars are brighter and seem closer. The locals say it's all for love. No wonder the reputation of Sochi as a place ideal for holiday romances is gracefully beaten up in the comedy Be My Husband.
The closer to the equator, the faster the day turns into night - a similar observation is noted by many people. In temperate climatic zones, twilight can last quite a long time, while at the equator the same period takes only a few minutes.
The daylight very quickly disappears over the horizon, a dark night sets in, which then just as rapidly gives way to day. Such an observation is completely objective, at the equator it really gets dark faster than in the temperate, subpolar zones. There is a perfectly reasonable explanation for this fact.
Trajectories of the Sun
The features of the position of the Earth relative to the Sun are such that in zones that are close to the poles, it is not observed high above the horizon, the movement occurs along a smooth trajectory. The smoothness of the angle is preserved at sunset, which is why the Sun takes a long time to ensure the onset of night.
Interesting fact: astronomers believe that the darkness of the night is observed from the moment the star goes 18 degrees below the horizon.
Closer to the equator, the trajectory of movement becomes steeper and sharper. Sunset at sunset occurs at a steep angle of almost 90 degrees, which allows it to quickly disappear over the horizon. Therefore, there is simply no long twilight at the equator, regardless of the time of year. Impressed by the quick change of day and night, tourists from the temperate zone may claim that the daylight leaves the horizon in a couple of minutes, but such a statement will not be true.
The practice of watching sunsets at the equator
If you observe the change of day in the equatorial zone, you can first of all note the high transparency of the air in a situation where the weather is fine. As a rule, the Sun shines very brightly literally until the moment the disk touches the horizon - despite the fact that in the temperate zone its light begins to dim in advance. The luminary quickly hides behind the horizon, after which it can get dark in some 10-20 minutes - and in half an hour it will already be deep night. However, it dawns just as fast at the equator, the whole process from the transition from complete darkness to saturated light takes all the same half an hour.
Local animals, plants are perfectly adapted to such a quick awakening, nature comes to life from the silence of the night and darkness almost instantly - just like it calms down in the evening. The same processes in the temperate zone can take three times as long for an equinox. Reducing the angle increases the distance that the luminary needs to travel before it disappears beyond the horizon, this significantly increases the time of twilight, stretches them.
Interesting fact: at the poles, twilight stretches to a two-week period. It happens twice a year, seeing off the polar summer and meeting it after the winter.
Why does the difference in angles arise, and how else does it affect the features of the planet?
Angles vary across climates for the simple reason that our planet is round and its axis is tilted. Because of this, the observant traveler may note that in the south, where he got out of the temperate zone on vacation, night comes faster. The closer to the pole, the longer the day in summer - but in winter it becomes much shorter. And at the equator, there are practically no annual changes in the duration of periods in days. Therefore, in summer the southern day will indeed be shorter than the northern one, while in winter the northern night will be longer than the southern one.
Thus, the closer to the equator, the faster the luminary leaves the horizon, making twilight very short, and this is due to the fact that at the equator the Sun goes beyond the horizon almost vertically, while the angle changes as it approaches the poles. In temperate latitudes, subpolar trajectories, twilight stretches for hours, while at the equator they take no more than half an hour all year round.
The right angle implies the minimum trajectory of the movement of the luminary across the sky during the period when it tends to the horizon or rises from it, while with a decrease in the angle the trajectory becomes longer, it takes a long time to pass it. The farther from the equator, the longer the twilight becomes, stretching from half an hour to two weeks at the poles - this is a feature of our planet, dictated by its shape and axial tilt.

One of the features of the equatorial belt that distinguishes it from the temperate and polar ones is the short duration of its twilight, the speed of the transition from day to night and vice versa. Since this is solely due to the vertical, and not tilted, rise and fall of the sun, the difference will be especially noticeable if we compare with the tropical twilight of our summer day. Even with us, the twilight at the time of the equinox is much shorter, and the twilight at the equator must be more than a third shorter than them.
Travelers, as usual, exaggerate the brevity of tropical twilight, arguing, for example, that after sunset one barely has time to read the page of a book. If we are talking about a book of medium format and about average speed of reading, then this is certainly not true, and I consider it necessary to describe, as accurately as possible, the true state of affairs.
When the weather is good, the air at the equator is somewhat more transparent than ours, and the brightness of the sunlight up to the moment when the sun's disk touches the horizon is usually very significant. When the sun has set, it immediately becomes noticeably darker - but over the next 10 minutes, the darkness hardly noticeably increases. But in the next 10 minutes, it gets dark very quickly, and about half an hour after sunset, almost full night reigns. In the morning, the contrasts are perhaps even more noticeable. Still at 5 1/2 hours it is completely dark, then here and there the cry of a bird begins to break the silence of the night, probably indicating by this that a glimpse of the morning dawn has already appeared in the east. A little while later, the melancholy cries of nightjars, the croaking of frogs, the mournful sounds of mountain thrushes, and, in general, the peculiar cries of various birds and mammals inhabiting the area begin to be heard. At about half past five it begins to get light: at first it dawns slowly, then so quickly that by a quarter to six it is almost completely light. During the next quarter of an hour, no significant change is imperceptible, but then the edge of the sun suddenly appears, covers the foliage, burdened with sparkling pearls of night dew, penetrates the forests far with golden rays and awakens all nature to life and bustle of business. Birds chirp and flutter, parrots scream, monkeys chirp, bees buzz through the flowers, and magnificent butterflies slowly soar in the air or sit with outstretched wings, illuminated by the life-giving rays of the sun. The first morning hour is full under the tropics of unforgettable charm and beauty. Everything was strengthened, refreshed by the coolness and moisture of the past night. Young leaves and buds open up almost before the eyes of the beholder, and the young shoots are often observed to have grown several inches since the evening; the freshness of the air is beyond description. The light coolness of early dawn, pleasant in itself, is softened by life-giving warmth, and the bright sun illuminates the delightful tropical vegetation, cloaking it with charm, which the magic brush of the artist and the fiery word of the poet presented to us as the ideal of earthly beauty.
Many travelers pay attention to the fact that it gets dark very quickly in the south. In the middle lane, twilight can last several hours, and in the hot equatorial parts of the world, night falls in a matter of minutes.
Equator
The answer is simple, the closer a country is to the equator, the faster the day turns into night. So the morning comes pretty quickly. The sun rises in less than 30 minutes. There is an explanation for this order.
Sun movement
In areas close to the poles, the Sun is not observed high above the horizon. In these regions, it moves along a smooth trajectory. The smooth angle is maintained during sunset. Therefore, the Sun needs more time to set. Night in such regions comes for a long time.
The closer to the equator, the steeper the trajectory of the Sun becomes. Sunset occurs at an angle almost reaching ninety degrees. This is what explains the sharp and fast entry. In countries near the equator, there is never a long evening; at any time of the year, night comes quickly. The sun goes below the horizon almost vertically. In this case, it would be erroneous to say that the Sun sets below the horizon in a few minutes.
Sunset and dawn
In the equatorial belt, the Sun remains bright and intense almost until it disappears below the horizon. In the temperate zone, the intensity decreases long before sunset. The same is true with dawn. At the equator, a clear hot morning comes swiftly. In the temperate zone, there is stretching and shortening of twilight depending on .
