Chapter 326 Chapter 326

Back in his bedroom, Li Shu dimmed the lights, leaned against the head of the bed and began to check Moments on his mobile phone.

It was snowing heavily outside the window, quiet and white.

inside the house.

The big yellow dog sleeps with its back leaning against the bed. Because there is floor heating in the house, it will not be cold, while the big orange cat, white squirrel, and thrush snuggle on the bed. The big orange cat purrs one after another, and there seems to be a quiet atmosphere in the air .

"Send the photos taken today to Moments!" Li Shu smiled, and the nine photos formed a nine-square grid, and then accompanied the text: [The first day in Greenland! 】

Li Shu then looked at his friends' circle of friends. When he liked and commented on other people's circle of friends, other people also liked and commented on him.

Xu Hao, Fan Biao, Ye Wenbo, Weike Na, Yan Zhang, Li Sha, Yu Bingbing, Wang Tianyuan, Cao Cao and others all commented, and Li Shu replied to them.

buzz buzz~

The phone vibrated suddenly. It turned out that Huang Yun had sent him a video invitation.

"Ashu, how about Greenland? I searched the information there, it is said that there is an aurora, I really want to see it." Huang Yun was wearing a light green skirt, and she was sitting cross-legged on the bed Eating apples, there is still a laptop on the computer table at the end of the bed, and there are advertisements for variety shows on it.

"There should be an aurora, but we haven't seen it yet. It's just snowing outside, and it's super beautiful." Li Shu posted a video of the big yellow dog rolling in the snow and the big orange cat making cat face imprints in the snow. For Huang Yun, this is what he just recorded.

"Wow, there's so much snow, huh? What is the big orange cat doing with its face in the snow?" Huang Yun's bed has curtains, which is a small enclosed space.

"It's funny, she seems to want to imprint her face on the snow." Li Shu pointed the camera at the sleeping big orange cat, big orange cat, white squirrel, and thrush sleeping together. Sleeping with one's neck together looks very warm and harmonious.

"Haha, the three of them seem to be sleeping soundly, I want to record the screen!" Huang Yun said and turned on the screen recording, "I read on the Internet that Greenland is super cold, and the temperature can reach minus 50 degrees in winter, right? real?".

Knowing that Li Shu had gone to Greenland, Huang Yun specially searched for a lot of information about Greenland. Before that, she didn't know that there was such a place in the world as Greenland.

"Well, Greenland is very large, more than 2 million square kilometers, and thousands of kilometers from north to south." Li Shu said with a smile: "The middle of the island and the north are covered with permafrost, and even glaciers that have not melted for thousands of years. Those places are still The polar night region, of course, is very cold."

"The capital where we are now is on the southwest corner, and it's not in the Arctic Circle. In summer, the ice and snow will melt, and flowers and plants will grow, so the temperature here is not so cold.

Besides, we are all wearing cotton-padded clothes, and there is floor heating indoors, so it won’t be cold. By the way, there is a big event tomorrow—the dog sled race. ".

"Okay, okay." Huang Yun was very happy, and she suddenly asked: "What is polar night? Some people say that Greenland is polar day, and some say it is polar night. I am confused.".

Li Shu suddenly laughed lowly: "The polar night is always night, and the night may last for several months, and the polar day is always day, and the day may last for several months, without night.

The earth can be regarded as a sphere, and the sun is much larger than the earth, so the light it shoots to the earth can be regarded as parallel light.

A line across the middle of the earth is the equator, but one of the reasons why we have changes in the seasons throughout the year is that the sun's rays do not always shine directly on the equator, but sway in a range north and south of the equator.

This range is between the "Tropic of Cancer" and the "Tropic of Cancer". The so-called "Tropic of Cancer" is the northernmost place where the sun is directly irradiated. The Tropic of Cancer passes through the five provinces of Guangdong, Guangxi, and Baodao.

And the day when the sun shines directly on the Tropic of Cancer is the "summer solstice" of the twenty-four solar terms in China. Standing near the Tropic of Cancer on that day, the sun is directly above the top of the head at noon, and the shadow falls just below the body! ".

"Hiss~ It looks so interesting, does the summer solstice shoot directly at the Tropic of Cancer?" Huang Yun asked.

"Basically, I can't be wrong. Well, this is the geography knowledge I learned in junior high school. It's a bit vague now. You can search it. If I'm wrong, just pretend I didn't say it." Li Shu laughed.

Huang Yun: "......".

"If you say something wrong, just pretend you didn't say it? Haha, why are you giving yourself a way out?" Huang Yun's smile trembled, her shoulders shrugged, and she suddenly felt that Li Shu was a little cute.

"I'm afraid of being slapped in the face." Li Shu smiled: "Continuing the topic just now, because the sun's light moves from the equator to the Tropic of Cancer, so the light it emits also moves north.

The moving distance is not short!

Because the equator is in the south of Singapore, direct sunlight moves north from the south of Singapore, passes through Malaysia, Thailand, Vietnam, and then reaches China. From summer to winter. ".

Huang Yun nodded excitedly: "Direct sunlight travels from the Tropic of Cancer to the Tropic of Cancer, and China goes from cold winter to spring, and then to midsummer; direct sunlight slowly returns from the Tropic of Cancer to the Tropic of Cancer, and then China goes from summer to autumn, and then to midsummer." Cold winter; the next year, the cycle will start again, and the four seasons will come back again! Hey! The four seasons will come out!

They are all one earth. I didn’t expect that just the difference in the position of direct sunlight can seriously affect the change of temperature, and even cause extreme climates such as midsummer and cold winter. ".

"That's right." Li Shu said with a smile: "It's easy to understand that the direct sunlight moves. When the direct sunlight moves from the equator to the Tropic of Cancer, the polar day phenomenon begins to appear at the North Pole, and the polar night phenomenon begins to appear at the South Pole.

The closer the direct sunlight is to the Tropic of Cancer, the larger the polar day range in the North Pole and the larger the polar night range in the Antarctic.

Of course, when the direct sunlight finishes irradiating the Tropic of Cancer, moves south to the equator, and then moves south after crossing the equator, polar night begins to appear at the North Pole, and polar day begins to appear at the South Pole.

This is what I understand, and there should be no mistakes. If I make mistakes, just pretend that I didn't say these words. ".

"Hahaha, um, I seem to understand." Huang Yun nodded, "So when the North Pole is in a state of polar night, the Antarctic is in a state of polar day, and vice versa. Isn't most of the land in Greenland now in a state of polar night? ?

It's winter in China now, so the sun must have run away and shot directly near the Tropic of Capricorn, otherwise China wouldn't be so cold, right? ".

"Yes." Li Shu said with a smile: "You have graduated from the teacher!".

"Hee hee, I've been smart since I was a child.".

"Ahem, boasting is okay." Li Shu said with a smile: "Actually, I have been thinking about whether to fly north and enter the polar night region of Greenland.".
