We finally couldn't wait to come to the North Pole in a flying saucer, but we didn't expect to be greeted not by the boundless white snow of the Himalayas that we take for granted, but by an boundless, dim and boundless darkness that I couldn't see my fingers, and I couldn't think about it, I couldn't find the north, because this is the North Pole, and it is extremely cold here, it is estimated that it is only minus fifty or sixty degrees, although we all wear strict and heavy cold-proof clothing, we still feel everywhere, the slightest cold, especially the frost and wind, those cunning Arctic winds are pervasiveSeeing the stitches suddenly creeping in through the gaps in our clothes, cutting heavily on our cheeks like sharp knives, we quickly pulled together the winter clothing, and felt better. When we turned on the lights, we saw a thick blue snow at our feet, and the vast ice sheet was boundless, endless, and seemed distant and quiet, as if time had been frozen, still, and frozen. At this time, all the waves and tides of the Arctic have disappeared, and it seems quieter, because the coast in the distance has been frozen with snow, and only the wind sweeps around with snow. You can also faintly see the huge icebergs on the sea, dozens of kilometers long, like a white land across the dark gray sea, it is really shocking, these wonderful and unique Arctic scenery makes us feel like we have come to another world. We walked on the creaking heavy snow, talking and laughing endlessly.

Duan Gongzi couldn't help but say: "It's really unfortunate that we came, this Arctic winter is not good, this Arctic is dark day and night, and you can't see your fingers." The Arctic has polar day and night phenomena, and the closer you get to the North Pole, the more obvious it is. Winter in the Arctic is long, cold and dark, starting on November 23 every year, and for nearly half a year there will be no sun at all. Temperatures can drop as low as minus 50°C. It is only in April that the weather in the Arctic warms up, the snow melts, the creeks gurgle and the sky brightens up and the sun shines on the earth. In May and June, when the plants are covered in the green of life, there is only a visible daylight. Autumn in the Arctic is short-lived, with the first snowstorm in early September. Other times, it's a long winter day with a lot of darkness in sight. ”

Hu Jiaojiao sighed and said, "Oh, I can't see anything in this black and swarthy body, it's really the wrong season." ”

Xiao Fei couldn't help but say with great interest: "Yes, the closer you get to the pole, the more obvious the meteorological and climatic characteristics of the polar regions. There, there is only one day and one night in a year. Even in the middle of summer, the sun is only far away on the southern horizon, glowing a bleak white light. The sun never rises above 23.5°, and it moves silently around the boundless white world. After a few months, the sun's trajectory gradually approached the horizon, and the twilight season of the Arctic began. The Arctic soon returned to cold, dark winters. ”

Zeng Lu suddenly pointed to the sky and shouted: "Oh my God, look at the sky, what is that? It's so beautiful, I have never seen such a colorful, beautiful, colorful, rare night sky in the world, it is really eye-opening and breathtaking." I feel that it is really a brilliant color that can only be found in heaven, what a dreamlike color, and it is difficult for any brush or paint to paint to paint that refreshing, dizzying beauty, it is really one of the most mysterious and beautiful wonders in nature. "When we look up, the boundless deep blue is like a velvety sky, and there is some splendor, deep and unpredictable, and the colorful veil-like posture of thousands of light bands, which is really the work of nature.

Xiao Fei looked up and said with a slight smile: "This is the aurora, these Eskimos are commonplace for them, we seem rare and strange, the aurora is a gorgeous and colorful luminous phenomenon that appears in the sky above the high magnetic latitude region of the north of the planet." Earth's auroras, on the other hand, are produced by the solar wind, a stream of high-energy charged particles from the Earth's magnetosphere or the sun, which excites or ionizes molecules or atoms in the upper atmosphere. Aurora is a brilliant and colorful luminous phenomenon due to the discharge of charged particles (solar wind) ejected by the sun at the high altitude of the earth's north and south poles under the action of the earth's magnetic field. Auroras are produced in the following conditions: the atmosphere, the Earth's magnetic field, and high-energy charged particles (solar wind). The Earth's aurora is generally green or red because oxygen and nitrogen atoms collide with charged particles in the thermal layer, emitting green and red light. The magnificence of the aurora depends on the intensity of the solar storm, and the complex composition of the excited particles determines the diversity of the aurora. Some aurora rays appear for a very short time, while others can frolic in the sky for hours. There are no two identical auroras in the world, just as there are no two identical leaves in the world. Auroras are divided into five categories according to their shapes: one is the auroral arc with neat and slightly curved bottoms, the second is the aurora belt with twists and wrinkles, the third is the auroral sheet like a cloud, the fourth is the auroral mantle with a veil like a veil, and the fifth is the ray-like aurora along the direction of the magnetic field line. ”

Duan Gongzi also said with enthusiasm: "In fact, there are records of the aurora in China for a long time, and this may be the earliest description of the aurora in history, so why is the aurora that should have appeared in the North Pole recorded in China, because there is a place in my country where you can see the natural wonder of the aurora." In Chinese legend, the birth of the Yellow Emperor Xuanyuan is associated with the aurora. Legend has it that more than 2,000 years ago, there was a young woman named Fubao sitting in the wilderness shrouded by the night, suddenly in the Big Dipper, floating out of a rainbow-like mysterious light belt, like smoke, swaying, turned into a huge halo, lingering around the Big Dipper, Fu Bao saw this scene, his heart moved, and then he was pregnant with Liujia, giving birth to the Yellow Emperor Xuanyuan. The "Classic of Mountains and Seas" also describes the aurora - beyond the Northwest Sea, north of Chishui, there is Zhangwei Mountain. There is a god, the face of the human snake is naked, the eyes are straight, the eyes are obscure, and the sight is clear. No food, no sleep, wind and rain are exhausted. It is the candle nine yin, and it is called the candle dragon. The candle dragon nine yin here refers to the aurora. It seems that our ancients traveled so far as the North Pole. ”
