My Deep-sea Fishery

The reason for this clean white weather in Antarctica is the low density of the polar air, the scarce water vapor, and the very weak ability to absorb sunlight.

When the sky is densely covered with clouds, the sun shines on the ice sheet through the clouds, and the light will reflect back and forth like two mirrors between the ice sheet and the dark clouds.

After multiple reflections of light, from the ocean to the land to the sky, the brightness of each part of the entire three-dimensional space will become completely consistent.

When the ground, ocean, and surrounding ice and snow reach the same brightness, the whole world becomes completely white when viewed with the naked eye.

After another moment, the white weather is not over yet.

At this time, Fang Youqun screamed again, and he wailed: "Brother Yang, how come this white weather is not over yet? I and my head are dizzy."

Xiang Yang frowned again, this time the Antarctic death light lasted a little longer.

"Dizziness and dizziness under the Antarctic dead light phenomenon are normal. If you really feel uncomfortable, close your eyes and don't look." Xiang Yang said.

Fang Youqun did not close his eyes as he said, but continued to ask Xiang Yang, "Brother Yang, does this pure white weather often occur in Antarctica?"

"How can it be?"

Xiang Yang laughed dumbly: "In addition to the dead light, there are many kinds of weird weather in Antarctica. Among the many weird weathers, the white weather can also be regarded as the rarest. Some polar scientific researchers have stayed in Antarctica for several years. I haven't been able to encounter it once."

"Ah? It's so rare, then I still don't close my eyes. I have to watch such a rare phenomenon for a while," Fang Youqun said.

Xiang Yang suddenly couldn't smile. It was Fang Youqun who said that his head was dizzy and complaining. It was Fang Youqun who said he wanted to watch more. Xiang Yang didn't know what to say.

At this time, Fang Youqun spoke again, and he asked, "Brother Yang, you said that there are many weird weather in Antarctica. Is there anything more weird than this?"

Xiang Yang thought about it, anyway, it's still idle now, it's better to chat with everyone for a while.

So Xiang Yang nodded and said, "Of course, there is no weird weather in Antarctica, only weird weather."

"Tell us about the weird weather, if we encounter it in the future, we might be mentally prepared." Fang Youqun said.

Xiang Yang pondered for a moment, "Speaking of the weirdest thing, of course it is a murderous style, but you must all know the murderous style. I will tell you a few things you don't know."

"First of all, it's the polar night, naturally."

There are no four seasons in Antarctica, only cold and warm seasons.

The cold season is from April to October, and the warm season is from November to March the following year.

In the cold season, Antarctica will have no daylight for seven consecutive months. This is called a polar night.

At this time, even near the Antarctic Circle, the sun could not be seen for five consecutive weeks.

But the aurora often appears at night, reflecting the snow on the ground, so the night in Antarctica is not completely dark.

Especially when the aurora is strong, people can even read books and newspapers.

At night, you can sometimes see the moon hanging low in the sky, hazy and hazy, like a jade plate, as if reaching out to touch it.

"Then it's very day and sunrise."

After the long night, the sun will appear.

But the sunrise in Antarctica is very unique, just like hide and seek.

At midnight, the sun will suddenly rise slowly from the horizon.

However, before anyone can appreciate it, the sun will sink below the horizon in an instant.

After a while, the sun will rise again from the east, and then sink.

Soon after, the sun will rise again from the north and then set from the west.

On the next day after day, the sun seemed to rise like a landing, hanging low on the horizon, spinning around in a circle from southeast-northwest-southwest-south.

For nearly two months in total, the sun did not set all day, but emitted strange lights at different times.

When the sun approaches the horizon, people are attracted to the reflected shadows for a long time, so the warm season is a long day instead of night.

"Of course, to say the most beautiful, it is undoubtedly the Southern Aurora."

Like the North Pole, the South Pole often shows aurora in the dark night sky.

The aurora in Antarctica is colorful, with five colors of red, green and yellow.

At the same time, the aurora also has many shapes, such as ribbons, curtains, arcs, and so on.

The aurora in Antarctica is not static like a rainbow.

Whenever the aurora appears, the aurora will be erratic like a streamer, unpredictable and dazzling, like entering a fairyland.

When the aurora is very strong, it is like the daytime, making the snow and ice land brightly glowing.

In addition, on the basis of the North and South Pole, some foreign scientists have simultaneously observed aurora with similar shape, equal brightness and uniform color.

Every time the aurora appears, the sky will be colorful.

In the same not-so-warm summer, or at the end of the summer, as long as the sun sets, the sky may appear bright and colorful.

Huge orange beams often appear on the eve of sunset.

At sunset, the sun has beams of light up and down.

In the afterglow of the setting sun, the light beam shows the reflection of the dragon in the water.

Sometimes, there are shorter beams on both sides of the beam, and holidays are still hanging on both sides.

Sometimes there will be a sun halo at sunset. The halo is also covered with a light wheel. There is an arc of light on the light wheel, and there is an aperture on both sides of the light wheel.

Sometimes there will be green light in the sky after sunset, and the blue light flashes under the green light. It looks like you are watching a science fiction movie, very beautiful.

These wonderful scenes can only be formed when the sun is illuminated properly and the atmosphere contains various shapes of ice crystals and snowballs. UU reading www.uukanshu.com

Scientists have already given a scientific explanation for the reasons for the formation of Antarctic aurora.

Green and blue light have shorter wavelengths in sunlight and are easily affected by ice crystals in the atmosphere.

Therefore, the beam of light in the aurora is actually a combination of vertical light reflected by ice crystals and snowballs.

Fang Youqun was very fascinated, and he was quite disappointed and said: "Why haven't I seen the aurora since I have been in Antarctica for so long, brother Yang, do you think we have a chance to see the aurora?"

Hearing this, Xiang Yang laughed and said: "What is the aurora? We have encountered pure white weather that is ten times rarer than the aurora. We are afraid that we will not see the aurora?"

Fang Youqun sighed, "But I still want to see the aurora. In this clean white weather, I feel like I am standing in a piece of snow, and there is heavy fog all around. The most important thing is that the fog is still very dazzling."

Xiang Yang grinned, "Could it not be dazzling, this white piece is all the refraction of light."
