Chapter 47 Semi-permafrost
After a day's trekking, Fang Hong got closer and closer to the north, and the climate became colder and colder. Pen, fun, pavilion www. biquge。 info
"Over the course of the day, it got a lot colder. ”
This is a special sign in Siberia, different from the kind of mountaineering that the climate has become colder, Siberia has moved north on flat land, getting colder and colder, and the temperature has dropped very much, just less than 20 kilometers away, the temperature has dropped by more than five degrees, which is simply poisonous.
"This is semi-permafrost in Siberia. ”
The so-called permafrost, also known as permafrost, actually means that there is no grass at all, and the iconic representatives are the Little Caucasus, the Himalayas, etc., which are covered by ice and snow.
In permafrost on flat ground, water is crystalline within 100 meters of the ground.
In this environment, it is impossible for trees to grow, not even shrubs.
Only a slight amount tends to be a tundra climate with mosses.
The so-called semi-permafrost means that it is covered with snow all year round, but vegetation grows, and its groundwater is not crystallized.
Of course, this is not an academic concept, but a description, which means that the ground is not visible here all year round, and it is covered with snow.
"Once you're here, it's not possible to find a river or a stream, but we might see a glacial lake. ”
Water is a very heat-tolerant liquid, and even in this area, once a lake of considerable size has formed, it will not freeze permanently.
Until the surface temperature drops to minus 3 degrees Celsius, the surface of the glacial lake does not necessarily freeze.
Because at zero degrees, it is a mixture of ice and water, and at zero temperatures, the ice lake will not freeze, but the water will not freeze so quickly when the temperature drops quickly.
As the saying goes, freezing three feet is not a day's cold, but the ice melts quickly, so there will be a spring flood in the Yellow River Basin in China, a season with little rain, it is because the frozen water in the upper reaches melts and swells downstream, so that the spring flood is formed.
Due to the sudden drop in temperature in the area not far away, the wind in this area is very strong.
Fang Hong was already preparing to camp and rest, but the wind was too strong, and Fang Hong needed to find a shelter.
"Brother Gun, where are you going to find a place?"
"I'm going to find a place to shelter from the wind in the north-south direction, the snow is thicker, dig up the snow and set up a tent in the middle. ”
The snow is dug up so that the tent is protected from heat loss by the snow layer.
Looking for a high place, Fang Hong looked around, but in the end he didn't find a particularly suitable place, so he could only camp on the side under the hillside, behind a tree that had just fallen on the ground.
There is a hillside on one side and a tree on the other, which is just enough to block the wind in both directions, but it may not be able to block it very tightly.
"The place is not bad, there is a frozen lake not far away, and you have to rely on fish to solve the problem of food at night, but it takes a lot of effort.
Fang Hong dug up the layer of snow, nearly fifty centimeters deep, camped in it, then widened the side of the door by two meters, dug it until it was bare ground, found some branches, and inserted them in the snow to form a chai tower.
"This thing lasts until two or three o'clock in the evening at most, after which it gets really cold and I need food to keep my body hot. ”
After lighting the fire, Fang Hong took out a branch, peeled off some birch bark, wrapped it around another branch, walked to the ice lake, swept away the snow, and built two branches on the ice, on which were the lit branches and torches made of birch bark.
"I hope this torch will melt the ice, and then dinner will be settled, or else there will be no food." ”
After setting the fire, Fang Hong returned to the camp, sat down in front of the tent, and lit a cigarette.
"Brother Gun, I heard that radio and television are going to start banning smoking shots in video works. ”
"It doesn't matter to me for the time being, just don't cut it in the documentary. ”
After the fire started, Fang Hong dragged the jacket down, wearing only a fleece lining, and the material of the jacket was easy to deform after being roasted by the fire.
"These torches are all erected on the snow, and if the fire burns close to the snow at night, the torches will be extinguished when the snow melts, but before I go to bed, I try to pile up the burning torches and plant new firewood on the periphery. ”
Chatting, it seemed that time passed quickly, Fang Hong took out a fish hook and fishing line from his bag, tied it to a branch, and took out a small bag containing crab meat peeled in the morning.
When they arrived at the lakeside, the torches were already about to be extinguished, and the two branches on the lower layer were completely soaked by the water, and the water had already overflowed, Fang Hong picked up the torch and rubbed the ice surface with the branches, and the last bit of thin ice was directly shattered.
"The light of the fire can attract the attention of the fish in the lake, hoping to catch a fish. ”
Fishing is different from spearfishing, fishing is about patience and luck, spearfish is quick with eyes, Fang Hong generally does not like this uncontrolled way to hunt.
However, I was lucky enough to catch a small fish, which weighed less than a pound, but it was enough for dinner.
There was snow all over the ground, and there were no stones to set up the pot, so I could only grill the fish.
Grilling fish, the night was already very dark.
Because of the light in front of him, it was particularly dark in the distance, and the whole world seemed to be only this pile of fire, and the whole world was shrouded in darkness.
On the horizon, a pink light gradually drifted over.
It was the Northern Lights, because the sailors strongly demanded the live broadcast and waited for the Northern Lights, so Fang Hongcai kept messing with the sailors just to wait for the Northern Lights.
The Northern Lights are unpredictable, colorful, and unpredictable, and the only natural beauty that can be compared to the Northern Lights is the Milky Way when the deep jellyfish and pink worms gather in large numbers.
"Our ancestors invented sparks 1,500 years ago, and fireworks appeared in the Song Dynasty, and this beauty in nature is more beautiful than regular fireworks. ”
The Northern Lights are unpredictable, sometimes they flicker and disappear, sometimes they can fill the sky for hours, sometimes they have only a trace, sometimes they are a strip, sometimes they are a net, sometimes they cover the entire sky.
This time it was lucky, although it wasn't the grand aurora borealis that covered the entire sky, but it was also a large piece, like an enlarged nebula.
The white light is like catkins, like flowing clouds, like white horses.
The orange light is like a candle flame, like a sunset, like a field of flowers.
The red light is like blood, like a flag, like silk.
Blue light is like a ghostly fire, like the waves of the sea, like ink.
The sky is like a canvas, and the invisible hand splashes ink, and a beautiful picture with no pictographic significance spreads out.
The clear sky makes the light shine thousands of miles away.
The mysterious geomagnetic field has allowed solar wind to dissolve atmospheric particles and generate a beautiful scenery that human beings have been willing to pursue for thousands of years.
Who said it wasn't, when someone saw this picture, shouldn't they think of the Nine Heavens Xuannu in fluttering clothes?
The secret snake dances, long and long, is it a fairy or a god, and it is more than a shadow in the sky?
"Brother Gun!"
"What?" Fang Hong looked at the sky: "Don't disturb me to watch the aurora." ”
"Brother Gun!"
"What, what, what?"
"It's paste, the fish is paste!"
A wisp of smoke is bound to go straight to the sky and dance with the aurora.
Fang Hong lowered his head: "My fish is not cooked yet, how can it be paste, it is not smoke." ”
"What's that?"
In the sky, a puff of white smoke mixed with the aurora, dancing with the solar wind and with the aurora.
