Sacred Mountain Tucson in Arizona. Panorama of Tucson. Virtual tour of Tucson. Attractions, map, photos, videos. In what weather is the sun more dangerous?

Tucson is located in southern Arizona, near the border with Mexico. The city's population is about half a million people.

The territory of the city was already developed by people several thousand years ago. The presence of Europeans in the structure of the city was not felt in this territory until the eighteenth century. The city's famous nickname is "Old Pueblo".

The region's economic strength and development is directly related to Arizona's higher education institutions. The Arizona Institute has 40 thousand students and is the largest educational institution in the state. The Institute is one of the largest employers in the region.

High-tech products, including military paraphernalia, play a significant role in the urban economy. Tourism is remarkably developed in the city district, as more than three million people visit it every year.

The southeast Tucson area is used as a high-tech cluster. Many large corporations and companies are based in this area. For example, Raytheon Corporation is the largest manufacturer of radio-controlled rockets. This company is considered the main employer in the region.

Climate of the region

The most important problem in the city is the insufficient amount of water resources. Across the city's perimeter is the Santa Cruz River system, but it does not meet all needs. This happens because the river becomes shallow due to the hot climate. The river bed is filled with water masses only during the season of heavy rains (monsoons).

Tucson is located in the famous Sonoran Desert. The urban area is surrounded by mountain ranges. It is considered interesting that, despite the deserted and lifeless zone, the landscape is very diverse. Under the clear sky of the desert area you can see: rolling hills, dry riverbeds, huge canyons, vegetation.

The climatic conditions, as you can already understand, are desert. Summer time here is long and hot. The temperature of the air masses is slightly lower than in. This is explained by the fact that the city area is located at an altitude of several hundred meters above the sea. On a summer day, the air temperature can rise to 38 degrees Celsius. At night, the temperature decreases slightly and drops only to 20-25 degrees. Extremely high temperatures (above 30 degrees) can also occur in October. The heavy rain season occurs in the last two summer months. During the winter months, daytime temperatures can reach 15-18 degrees Celsius. During this period, precipitation sometimes occurs in the form of snow, which instantly melts.

Economy

Tucson is a transport hub for the Central Region's irrigated agriculture, pastoral livestock (sheep, goats, cows) and mining industries. Copper ore, polymetals, and uranium ore are mined in the surrounding mountains, and copper smelting takes place in the city itself.

Attractions

To the northwest of the city is the Saguaro National Natural Monument, which is a cactus forest. Nearby there is a winter climatic resort of national importance (treatment of respiratory diseases).

72 km from the city is the Kitt Peak Astronomical Observatory, a US national observatory located on Mount Kitt Peak (2095 m).

Near the city there is the Davis Monten Air Force Base with the largest cemetery of obsolete aircraft.

Population

The population of Tucson in 1974 was only 285 thousand inhabitants. The city is one of the popular destinations for retirees and people of pre-retirement age. The population of the city itself, according to data for 2006, is 519 thousand people, with its suburbs - 946 thousand. The ethnic composition of the population is very diverse. White Americans make up about 69.7% of the population (including 47.2% non-Hispanic), 36% are Mexican (regardless of race), 5.0% are African American, 2.9% are Asian, 2. 7% are Indians, 0.2% are from Oceania. The city has many illegal migrants from neighboring Mexico. Per capita income in the city is therefore low - about $16,000 per person per year (for the United States as a whole, 41,000).

- Wait, Sonya, you will understand everything. You will see what kind of person he is. Don't think bad things about me or him. – I don’t think anything bad about anyone: I love everyone and feel sorry for everyone. But what should I do? Sonya did not give in to the gentle tone with which Natasha addressed her. The softer and more searching the expression on Natasha’s face, the more serious and stern Sonya’s face was. “Natasha,” she said, “you asked me not to talk to you, I didn’t, now you started it yourself.” Natasha, I don't believe him. Why this secret? - Again, again! – Natasha interrupted. – Natasha, I’m afraid for you. - What to be afraid of? “I’m afraid that you will destroy yourself,” Sonya said decisively, herself frightened by what she said. Natasha's face again expressed anger. “And I will destroy, I will destroy, I will destroy myself as quickly as possible.” None of your business. It will feel bad not for you, but for me. Leave me, leave me. I hate you. - Natasha! – Sonya cried out in fear. - I hate it, I hate it! And you are my enemy forever! Natasha ran out of the room. Natasha no longer spoke to Sonya and avoided her. With the same expression of excited surprise and criminality, she walked around the rooms, taking up first this or that activity and immediately abandoning them. No matter how hard it was for Sonya, she kept an eye on her friend. On the eve of the day on which the count was supposed to return, Sonya noticed that Natasha had been sitting all morning at the living room window, as if expecting something, and that she made some kind of sign to a passing military man, whom Sonya mistook for Anatole. Sonya began to observe her friend even more carefully and noticed that Natasha was in a strange and unnatural state all the time during lunch and evening (she answered questions asked to her at random, started and did not finish sentences, laughed at everything). After tea, Sonya saw a timid girl's maid waiting for her at Natasha's door. She let her through and, listening at the door, learned that a letter had been delivered again. And suddenly it became clear to Sonya that Natasha had some terrible plan for this evening. Sonya knocked on her door. Natasha didn't let her in. “She'll run away with him! thought Sonya. She is capable of anything. Today there was something especially pitiful and determined in her face. She cried, saying goodbye to her uncle, Sonya recalled. Yes, it’s true, she’s running with him, but what should I do?” thought Sonya, now recalling those signs that clearly proved why Natasha had some terrible intention. “There is no count. What should I do, write to Kuragin, demanding an explanation from him? But who tells him to answer? Write to Pierre, as Prince Andrei asked, in case of an accident?... But maybe, in fact, she has already refused Bolkonsky (she sent a letter to Princess Marya yesterday). There’s no uncle!” It seemed terrible to Sonya to tell Marya Dmitrievna, who believed so much in Natasha. “But one way or another,” Sonya thought, standing in the dark corridor: now or never the time has come to prove that I remember the benefits of their family and love Nicolas. No, even if I don’t sleep for three nights, I won’t leave this corridor and forcefully let her in, and I won’t let shame fall on their family,” she thought. Anatole recently moved in with Dolokhov. The plan to kidnap Rostova had been thought out and prepared by Dolokhov for several days, and on the day when Sonya, having overheard Natasha at the door, decided to protect her, this plan had to be carried out. Natasha promised to go out to Kuragin’s back porch at ten o’clock in the evening. Kuragin had to put her in a prepared troika and take her 60 versts from Moscow to the village of Kamenka, where a disrobed priest was prepared who was supposed to marry them. In Kamenka, a setup was ready that was supposed to take them to the Warsaw road and there they were supposed to ride abroad on postal ones. Anatole had a passport, and a travel document, and ten thousand money taken from his sister, and ten thousand borrowed through Dolokhov. Two witnesses - Khvostikov, a former clerk, whom Dolokhov used for games, and Makarin, a retired hussar, a good-natured and weak man who had boundless love for Kuragin - were sitting in the first room having tea. In Dolokhov’s large office, decorated from walls to ceiling with Persian carpets, bear skins and weapons, Dolokhov sat in a traveling beshmet and boots in front of an open bureau on which lay abacus and stacks of money. Anatole, in an unbuttoned uniform, walked from the room where the witnesses were sitting, through the office into the back room, where his French footman and others were packing the last things. Dolokhov counted the money and wrote it down. “Well,” he said, “Khvostikov needs to be given two thousand.” “Well, give it to me,” said Anatole. – Makarka (that’s what they called Makarina), this one will selflessly go through fire and water for you. Well, the score is over,” said Dolokhov, showing him the note. - So? “Yes, of course, so,” said Anatole, apparently not listening to Dolokhov and with a smile that never left his face, looking ahead of him. Dolokhov slammed the bureau and turned to Anatoly with a mocking smile. – You know what, give it all up: there’s still time! - he said. - Fool! - said Anatole. - Stop talking nonsense. If only you knew... The devil knows what it is! “Come on,” said Dolokhov. - I'm telling you the truth. Is this a joke you're starting? - Well, again, teasing again? Go to hell! Eh?...” Anatole said with a wince. - Really, I have no time for your stupid jokes. - And he left the room. Dolokhov smiled contemptuously and condescendingly when Anatole left. “Wait,” he said after Anatoly, “I’m not joking, I mean business, come, come here.” Anatole entered the room again and, trying to concentrate his attention, looked at Dolokhov, obviously involuntarily submitting to him. – Listen to me, I’m telling you for the last time. Why should I joke with you? Did I contradict you? Who arranged everything for you, who found the priest, who took the passport, who got the money? All I. - Well, thank you. Do you think I'm not grateful to you? – Anatol sighed and hugged Dolokhov. “I helped you, but I still have to tell you the truth: it’s a dangerous matter and, if you look at it, stupid.” Well, you take her away, okay. Will they leave it like this? It turns out that you are married. After all, they will bring you to criminal court... - Ah! nonsense, nonsense! – Anatole spoke again, wincing. - After all, I explained it to you. A? - And Anatole, with that special passion (which stupid people have) for the conclusion that they reach with their minds, repeated the reasoning that he repeated to Dolokhov a hundred times. “After all, I explained to you, I decided: if this marriage is invalid,” he said, bending his finger, “then I don’t answer; Well, if it’s real, it doesn’t matter: no one abroad will know this, right? And don't talk, don't talk, don't talk! - Really, come on! You will only tie yourself... “Get to hell,” said Anatole and, holding his hair, he went into another room and immediately returned and sat down with his feet on a chair close in front of Dolokhov. - The devil knows what it is! A? Look how it beats! “He took Dolokhov’s hand and put it to his heart. - Ah! quel pied, mon cher, quel regard! Undeesse!! [ABOUT! What a leg, my friend, what a look! Goddess!!] Huh? Dolokhov, smiling coldly and shining with his beautiful, insolent eyes, looked at him, apparently wanting to have more fun with him. - Well, the money will come out, then what? - What then? A? – Anatole repeated with sincere bewilderment at the thought of the future. - What then? I don’t know what’s there... Well, what nonsense to talk about! – He looked at his watch. - It's time! Anatole went into the back room. - Well, will you be there soon? Digging around here! - he shouted at the servants. Dolokhov removed the money and, shouting to the man to order food and drink for the road, he entered the room where Khvostikov and Makarin were sitting. Anatole was lying in the office, leaning on his arm, on the sofa, smiling thoughtfully and gently whispering something to himself with his beautiful mouth. - Go, eat something. Well, have a drink! – Dolokhov shouted to him from another room. - Don't want! – Anatole answered, still continuing to smile. - Go, Balaga has arrived. Anatole stood up and entered the dining room. Balaga was a well-known troika driver, who had known Dolokhov and Anatoly for six years already, and served them with his troikas. More than once, when Anatole’s regiment was stationed in Tver, he took him out of Tver in the evening, delivered him to Moscow by dawn, and took him away the next day at night. More than once he took Dolokhov away from pursuit, more than once he took them around the city with gypsies and ladies, as Balaga called them. More than once he crushed people and cab drivers around Moscow with their work, and his gentlemen, as he called them, always rescued him. He drove more than one horse under them. More than once he was beaten by them, more than once they plied him with champagne and Madeira, which he loved, and he knew more than one thing behind each of them that an ordinary person would have deserved Siberia long ago. In their revelries, they often invited Balaga, forced him to drink and dance with the gypsies, and more than one thousand of their money passed through his hands. Serving them, he risked both his life and his skin twenty times a year, and at their work he killed more horses than they overpaid him in money. But he loved them, loved this crazy ride, eighteen miles an hour, loved to overturn a cab driver and crush a pedestrian in Moscow, and fly at full gallop through the Moscow streets. He loved to hear behind him this wild cry of drunken voices: “Go! let's go! whereas it was already impossible to drive faster; He loved to pull the man's neck painfully, who was already neither alive nor dead, avoiding him. "Real gentlemen!" he thought.

Tucson is a large city located in the state of Arizona, and is the administrative center of Pima County. The city is one of the fastest growing in the United States. According to the 2008 census, the population of the city itself is about 542 thousand inhabitants. This makes the city the second largest city in Arizona. In first place is the state capital of Phoenix.

The city is located in southern Arizona, in a picturesque oasis of the Santa Cruz River Valley in semi-desert areas. Located 188 km southeast of Phoenix. The city is constantly experiencing an acute shortage of water resources.

For a long time, the only inhabitants of these places were the Navajo Indian tribes. And the first European military fort appeared here in 1768. It was founded by the Spaniards, after which the city was under the control of the Spanish Crown for a long time, and then came under the jurisdiction of independent neighboring Mexico. The city became part of the United States in 1853, and the rapid development of the city began only in 1877.

In this city, on January 8, 2011, near the Safeway supermarket, there was a high-profile attempt on the life of Gabriel Giffords, a well-known member of the US House of Representatives from Arizona. Then 6 people were killed and 14 residents were injured.

This city is currently a major center for the production of radio electronics, guided missiles and the assembly of modern aircraft. The innovative production of optoelectronics and optical devices is well developed here. Sometimes Tucson is even called the “Valley of Optics”, by analogy with the famous “Silicon Valley”.

In the local mountainous area, copper ore is actively mined. Copper smelting has been established in the city itself. This city is home to Arizona's largest university. The city of Tucson is a hub for the Central Region's ranching, irrigated agriculture and mining industries. Uranium ore, copper and polymetals are mined here.

Numerous tourists in this city are attracted by ancient buildings of Spanish architecture. There are many museums here. This is, first of all, the Arizona State Museum and a famous art museum that exhibits Latin American art. As well as the Arizona Historical Society Museum.

In the very center of the city there is a beautiful historical quarter, recently renovated. It was once part of a Spanish fort. In the northwest of the city is the Saguaro National Natural Monument, which means cactus forest. A popular winter climatic resort of national importance is located nearby. Many diseases of the respiratory and heart organs are successfully treated here.

The US National Astronomical Observatory is located 72 km from the city on Mount Kitt Peak.

And very close to the city is the Davis Monten Air Force Base, where you can find the largest cemetery of obsolete military aircraft.

In 1974, Tucson's population was only about 285 thousand residents. This City is the most popular destination for American retirees. The population of the city of Tucson, according to the 2006 census, is about 520 thousand people, and together with the suburbs it is about 950 thousand. The ethnic composition of the city is very diverse.

Tucson (Spanish Tucson, English Tucson [ˈtuːsɒn]) is a large city in the state of Arizona, USA and the administrative center of Pima County. It is one of the fastest growing cities in the USA.

Population

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

What kind of UV radiation from the sun is there?

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

UVA. Long-wave radiation range 
315–400 nm

The rays pass almost freely through all atmospheric “barriers” and reach the Earth.
UV-B. Medium wave range radiation 
280–315 nm

The rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.
UV-C. Shortwave range radiation 
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 effects of the Sun. However, these life-saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in spring, and the minimum in autumn. Cloudiness is one of the most variable characteristics of weather. The carbon dioxide content also changes all the time.

At what UV index values is there a danger?

The UV index provides an estimate of the amount of UV radiation from the Sun at the Earth's surface. UV index values range from a safe 0 to an 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, the UV index reaches 9...11+ points throughout the year.

What are the benefits of the sun?

In small doses, UV radiation from the Sun is simply necessary. The sun's rays synthesize melanin, serotonin, and vitamin D, which are 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.

The hormone of happiness 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 the beneficial and harmful Sun is very thin. Excessive tanning always borders on a burn. Ultraviolet radiation damages DNA in skin cells.

The body's defense system cannot cope with such aggressive influence. It lowers immunity, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet light destroys the DNA chain

How the Sun affects people

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

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

Who is most influenced by the Sun?

People with fair hair 
skin tone

People with many moles

Residents of mid-latitudes during a holiday in the south

Winter lovers 
fishing

Skiers and climbers

People with a family history of skin cancer

In what weather is the sun more dangerous?

It is a common misconception that the sun is dangerous only in hot and clear weather. You can also get sunburned in cool, cloudy weather.

Cloudiness, no matter how dense it may be, does not reduce the amount of ultraviolet radiation to zero. In mid-latitudes, cloudiness significantly reduces the risk of getting sunburned, which cannot be said about traditional beach holiday destinations. For example, in the tropics, if in sunny weather you can get sunburned 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 simple rules:

Spend less time in the sun during 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

Sunscreens vary in degree of sun protection and are labeled from 2 to 50+. The numbers indicate the proportion of solar radiation that 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 ultraviolet 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 can reflect 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 or higher. 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 check the cream instructions for the required volume for application.

How to Apply Sunscreen When Swimming

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

Excessive sweating and wiping with a towel are also reasons to re-protect the skin.

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

How to protect your eyes

Sunlight reflected from water, snow or sand can cause painful burns to the retina. To protect your eyes, wear sunglasses with a UV filter.

Danger for skiers and climbers

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

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

Thus, in the mountains the Sun is most dangerous. It is necessary to protect your face, lower chin and ears even in cloudy weather.

How to deal with sunburn if you get sunburned

Use a damp sponge to moisten the burn.

Apply anti-burn cream to the burned areas

If your temperature rises, consult your doctor; you may be advised to take an antipyretic

If the burn is severe (the skin swells and blisters greatly), seek medical attention
