Aurora borealis reading answer

Aurora comes from Latin Ios. Legend has it that Ios is the incarnation of "Dawn" in Greek mythology, the daughter of the Greek god Titan and the sister of the sun god and the moon goddess. The Northern Lights in the Arctic (1 1 picture) The Arctic has been a mystery since the first time humans looked up at the sky and saw the Northern Lights. For a long time, people have their own legends of aurora. For example, in Finnish, the northern lights are called "revontulet", which literally means fox's fire. Ancient Finns believed that when a fox ran on a snowy hillside, its tail would roll up glittering snowflakes and stretch all the way to the sky, thus forming the Northern Lights. [1] In addition, some Sami and Siberian people believe that the Northern Lights come from the wounds of the dead, but this colorful sky is not a sign of pain. On the contrary, it is the blood left by ghosts who were injured while playing ball or riding horses in later generations. Eskimos believe that "Aurora is a torch for ghosts and gods to guide the souls of the dead to heaven". The aborigines, on the other hand, regard "aurora as the appearance of gods, and think that the fast-moving aurora will make the gods trample on the empty voice, take away people's souls and leave bad luck". Aurora in the Arctic upper atmosphere.

Basic information

There have been different opinions about the causes of the aurora since the long-term collection of 20 pictures of the northern lights. Some people think that it is a fire burning at the outer edge of the earth; Some people think it is light reflected from the sky after sunset; Others believe that it is an energy released by polar ice and snow at night after absorbing and storing sunlight during the day. It was not until man sent a satellite rocket into space that the mystery of this celestial phenomenon was explained physically. [2]

Research course

For a long time, people have been eager to understand and explore the mystery of aurora. In the last century, people used cameras, video cameras and satellites to clearly see and understand the discharge phenomenon caused by the collision between solar energy and the earth's magnetic field. It is a river of electron light, releasing one million megawatts of light in the sky 60 miles away from the earth. In an unscientific era, people can describe this wonderful natural scenery as long as they use their infinite imagination, so there are many mysterious legends handed down from ancient times. The origin of the name of the Northern Lights is that the scientist Cassidy called this phenomenon "Aurora" after repeated consideration. She is the goddess of weaving in ancient Roman mythology, representing the dawn before sunrise. Bekele, a scientist, believes that electrons emitted by the sun fly freely in space. When they break into the earth's magnetic field, electrons collide with gas and emit light. This is the Northern Lights. His theory was not proved until 60 years later. Scientists first proved that the earth has two magnetic fields after the launch of American rocket 14. A year later, Harbor 2 first measured the plasma of the sun (the charged substance that constitutes the solar airflow), and the solar airflow can touch the earth. Solar airflow is also called solar wind. These radiations rushed to the earth at a speed of 3 million kilometers. Fortunately, the earth's magnetic field changed the direction of the solar wind and protected us from it. When the solar wind collides with the earth's magnetic field, it will generate 654.38+000 trillion yuan of energy, small particles in the earth's atmosphere will release energy, oxygen atoms will emit green or red light, oxygen molecules will emit red or yellow light, and nitrogen molecules will emit purple or pink light. Although scientists have learned a lot about the causes of the aurora at present, the aurora still leaves many problems for people to continue to explore its mystery, such as whether there is sound in the aurora. Aboriginal people in Canada's Arctic Circle say that the Northern Lights will send out whistles and footsteps, which is the sound of souls crossing the snow in heaven. How much energy will be released when the solar wind hits the earth's magnetic field? Wait, these are all mysteries that scientists are eager to solve. Aurora, like itself, is like smoke and fog, which makes us sigh the wonder of nature's creator.

fundamental principle

Aurora is essentially an optical phenomenon excited by the operation of atoms and molecules in the uppermost layer of the earth's atmosphere (above the ground 100-200 km). It is formed by three elements: solar wind, earth's magnetic field and atmosphere. The so-called "solar wind" is the influence of the sun on the Northern Lights.

The energy constantly radiated by the universe composed of electrons and protons. Due to the intense activity of the sun, countless charged particles are emitted. When charged particles flow to the earth and enter the range of the earth's magnetic field, they will enter the upper atmosphere near the north and south magnetic poles at high speed along the earth's magnetic field lines, and collide with particles such as oxygen atoms and nitrogen molecules, resulting in "electromagnetic storms" and "visible light" phenomena, which become a striking "aurora".

Edit where this paragraph appears.

Aurora is most common in two circular belts near the north-south magnetic latitude of 67, which are called the Southern Aurora and the Northern Aurora respectively. The northern hemisphere is dominated by Alaska, northern Canada, Siberia, Greenland, the southern tip of Iceland and the northern coast of Norway; The southern hemisphere is concentrated near Antarctica. It is worth mentioning that Alaska and northern Canada near the North Pole are the best places to watch the aurora. Fairbanks in Alaska has won the reputation of "Northern Lights Capital" and is famous for its long-term illumination in cold winter and summer. During the year, the Northern Lights appear over the fjord near Reykjavik, Iceland.

After 200 days of the aurora phenomenon, people go there to enjoy its spectacular scenery and witness the aurora wonders that appear every night. If you have the chance to go to Alaska, you must go to see the charming Northern Lights, capture the ever-changing super "electro-optic show", and you will completely fall in love with the Northern Lights!

Edit the morphological characteristics of this paragraph

Aurora is a natural astronomical wonder. It has no fixed pattern and different colors. The colors are mostly green, white, yellow and blue, and occasionally they show gorgeous red and purple, graceful and mysterious. Aurora can only be seen in cold autumn and winter nights and high latitudes. The best time is from 10 in the afternoon to 2 am, and sometimes it lasts about 1 hour. Generally speaking, there are four types of aurora: arc aurora, ribbon aurora, curtain aurora and radial aurora. What appears in the north is called the Northern Lights, and what appears in the south is called the Southern Lights.

Shooting the Northern Lights is a unique challenge. Because the northern lights are very popular in winter, the weather is very cold, and the temperature will be MINUS 40 or 50 degrees. The camera should not be left outside for more than a few minutes, because it will freeze. Film is not as sensitive as human eyes, and it uses special time interval technology.

Characteristics of TV series

"Northern Lights" is the first medium-length TV series reflecting the work and life of meteorologists in China. Writer Rong wrote the first draft of Northern Lights, and writer Li Wei later revised it again. The whole script was revised eight times before and after. Ma Xuqing, the producer's representative, said that the title of the film "Northern Lights" has two meanings: one represents the place where the protagonist lives-Mohe, where you can see the "Northern Lights". The other layer also shows the exploration of meteorology. The play is divided into two parts. The first part mainly reflects the ice and snow in Northeast China, and the second part focuses on the green of Guangzhou and Nanjing. The first and second chapters are in sharp contrast between the harsh environment and city life. The play was jointly invested by China Meteorological Bureau and Heilongjiang Meteorological Bureau and filmed by Harbin TV Station. The main creative unit is changchun film studio, and the general director is Song Jiangbo, artistic director of changchun film studio and judge of Rome Film Festival. The earliest screening time of this drama will be in early May or late June, and the broadcast channel is initially set at the central eight sets of golden section. Our hospital is committed to providing support for actors. Dean Sun served as the chief meteorological consultant of the play, and some teachers and classmates acted as extras in the play. Professor He Jinhai, a famous meteorologist, rushed to the crew for rehearsal despite fatigue. It is understood that there are 60,000 meteorologists in China, and the public lacks understanding of their work, especially their dedication to the meteorological cause. Through this TV series, the public can not only understand the important role of meteorology in flood control and drought relief and construction, but also deepen their understanding of meteorological work, meteorological undertakings and meteorological workers, which plays an important role in creating meteorological culture and shaping meteorological spirit.

Story summary

In 1950s, Zhang Beixing, a young demobilized soldier, was assigned to a small weather station in Daxinganling, Heilongjiang Province. Zhao Qingshan, the old stationmaster here, and his twenty-year-old daughter Yaner warmly received him. The enthusiasm, selflessness and meticulous spirit of the old stationmaster deeply infected and attracted him, which made him interested in the work of the weather station. This is Nannan, the girlfriend of Guangzhou's hometown, who came here specially, hoping that he could be transferred back to Guangzhou to work and leave this sparsely populated and desolate old mountain forest. The beloved does not ask too much of him, but he cannot leave this land. Suddenly, a telegram fell from the sky and his father died of illness. Zhang Beixing was in great pain and went back to Guangzhou to attend the funeral. In the face of lonely and sick old mother, Zhang Beixing once again faces a choice. As it happens, Nannan found a job for Zhang Beixing in Guangzhou, but Zhang Beixing remembered the small weather station in the snowy area and felt that he was needed there, so he resolutely persuaded his mother to break up and return to Daxinganling. Zhao Qingshan, the old stationmaster, died in the snowstorm in order to retrieve a meteorological data on a snowy night, which made him feel the burden on his shoulders. At this time, he received a new task to build a new weather station, which is the northernmost part of China-the cold and snowy Arctic village. He said goodbye to the geese and set off on a journey. In the most difficult time to build a station, Yaner came to his side. She has become a new employee of the weather station. The ideal of * * * and the hobby of * * * bear the fruit of love. They fell in love, got married and gave birth to a son. After his son was born, Zhang Beixing accepted the new task of building a station. Zhang Beixing walked for five years, and when he came back, his son's drawer was five years old. The drawer doesn't know his father, and he doesn't call him dad, let alone let strangers sleep next to his mother. Zhang Beixing is in great pain. At this time, Yaner found that all the meteorological instruments in the weather station were destroyed. After repeated investigation, I know this is my son's drawer. Zhang Beixing understands that his son wants to get more love by doing this, but he can't give up his meteorological career. His work is more and more energetic and he has made greater achievements. Forty years passed in an instant, and in the 1990s, Zhang Beixing retired. He can't let go of his work in the weather station and often makes suggestions, which makes his son drawer, who has become a new stationmaster, extremely disgusted. Zhang Beixing received a letter from his second son: he will graduate soon. He was afraid that his son in Nanjing Institute of Meteorology would not be able to go home after graduation, so he secretly left home and went to Nanjing Institute of Meteorology. But when he arrived in Nanjing, his son had gone to Guangzhou with his girlfriend and his classmate Wei Wei. Coincidentally, this female classmate Wei Wei is the daughter of Zhang Beixing's former lover Nan Nan. Nannan later married a wealthy businessman and gave birth to this daughter. Later, she divorced because of emotional discord, and lived a rich but boring life alone. When she knew that her daughter's boyfriend was Zhang Beixing's son, she strongly opposed it. What worries her most is that the boy will take his daughter to the north. Zhang Beixing chased Guangzhou and met Nan Nan before he knew that his son had returned to the Northeast with his girlfriend. He doesn't object to this marriage, but he hopes that both children can go to the north, and they have nothing to argue about. At this time, the physical examination found that Zhang Beixing had stomach cancer. Nannan sent him to the hospital and had an operation, which was very successful. After decades of ups and downs, Nan Nan really understood Zhang Beixing. After the operation, the two returned to the northeast. The second son, Wei Dong, had a classmate named Xiao Xia in middle school. Xiao Xia has always liked Wei Dong for many years, and he also hopes that Wei will take her out of the mountains after graduation. But when Wei Dong brought back a beautiful girlfriend, she was jealous and said something to Wei Wei. After Wei Dong returned to his hometown, he spread scientific knowledge for the weather station in his hometown and did many useful things. He also explicitly told Xiao Xia that he already had a girlfriend, and told Xiao Xia not to wait any longer. After Zhang Beixing returned to the northeast, he suffered a once-in-a-century flood. With many years of meteorological experience and the new scientific knowledge of his second son Weidong and his girlfriend, he helped the provincial flood control headquarters make major decisions. They predicted that the heavy rain could stop within 24 hours without blasting the dam to divert the flood. Saved people's lives and property, and won the victory of flood control. Amid the cheers, the old stationmaster fell asleep with fatigue. Yan Er and Nan Nan sent him meals together, and the drawer filled with hot porridge was called "Dad" for the first time! Zhang Beixing was awakened by this affectionate cry, and his eyes were full of tears. He got up and walked, his back melted in the sunshine of Chu Qing after the rain.
