My Deep-sea Fishery

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

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

After the light is reflected many times, from the ocean to the land to the sky, the brightness of each part will become completely consistent in the entire three-dimensional space.

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

After a while, the white weather is not over yet.

At this time, Fang Youqun complained again. He wailed, "Brother Yang, why is this white weather not over yet? I'm dizzy."

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

"Dizziness is normal under the Antarctic death light phenomenon. If you really feel uncomfortable, then close your eyes and don't look at it." Xiang Yang said.

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

"How can it be?"

Xiang Yang laughed dumbly and said: "In addition to the dead light, there are many kinds of weird weather in Antarctica. Among the many weird weather, white weather can be regarded as the most rare. Some polar scientific research personnel have stayed in Antarctica for several years. I haven't been able to meet it once."

"Ah? It's so rare, so I'd better not close my eyes. I need to watch for such a rare phenomenon." Fang Youqun said.

Xiang Yang couldn't help but smile bitterly. Well, it was Fang Youqun who was dizzy and complaining, and it was Fang Youqun who said he needed to watch for a while. Xiang Yang didn't even know what to say.

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

Xiang Yang thought, since he is idle now, he might as well chat with everyone for a while.

Therefore, Xiang Yang nodded and said: "Of course there is. In Antarctica, there is no weirdest weather, only weirder weather."

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

Xiang Yang pondered for a moment, "If you want to talk about the weirdest thing, of course it is the murderous style, but you must all know the murderous style, so let me tell you a few things you don't know."

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

Antarctica does not have four seasons, only cold and warm.

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

During the colder season, Antarctica goes seven months without daylight, known as the polar night.

At this time, the sun is not visible for five consecutive weeks, even near the Antarctic Circle.

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

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

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

"And then there's the extreme day and the 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 over 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 in the east again, and then sink.

Immediately afterwards, the sun rises from the north and sets from the west.

Day after day, the sun seemed to rise as if it had landed, and hung low on the horizon, circling endlessly in a southeast-northwest-southwest-south circle.

For nearly two months in all, the sun didn't set all day long, but gave strange lights at different times.

People are drawn to reflected shadows for a long time when the sun is near the horizon, so the warmer seasons are long days rather than nights.

"Of course, the most beautiful one is undoubtedly the Southern Lights."

Like the North Pole, the Antarctic often features auroras in dark night skies.

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

At the same time, there are many shapes of aurora, such as ribbons, curtains, arcs and so on.

The aurora in Antarctica is not fixed like a rainbow.

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

When the aurora is strong, it is like daytime, making the snowy land glow brightly.

In addition, foreign scientists once observed auroras with similar shapes, equal brightness, and consistent colors at the same time on the basis of the North Pole and the South Pole.

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

On a less warm summer day, or towards the end of summer, the sky can be filled with brilliant colors as soon as the sun goes down.

Huge orange beams often appear just before sunset.

At sunset, there are beams of light above and below the sun.

In the afterglow of the setting sun, the beams show the reflection of the dragon in the water.

Sometimes there are shorter beams on either side of the beam, with holidays still hanging on the sides.

Sometimes there is a sun halo at sunset, and the halo is also covered with a light wheel with an arc of light and a circle of light on either side of the light wheel.

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

These wonderful scenes can only be created when the sun is shining just right and the atmosphere contains ice crystals and snowballs of all shapes and sizes.

Scientists have long given scientific explanations for the formation of the Antarctic Aurora.

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

So, the light beams in the aurora are actually a combination of vertical rays reflected by ice crystals and snowballs.

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

When Xiang Yang heard the words, he immediately laughed and said, "What is the aurora? We have even encountered pure white weather that is ten times rarer than the aurora. Are we afraid that we may not see the aurora?"

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

Xiang Yang grinned, "Can it not be dazzling, this is pure white, but it's all the refraction of light."
