Chapter 644: Blizzard at the Border of Warmth and Coldness
"In fact, some people say that the prototype of the red-haired character in One Piece is Eric the Red-haired. I don't know about this. It's just hearsay. Just listen to it."
Bifang took a breath.
Walking on the ice field was too tiring. For safety reasons, he could not walk too fast, otherwise the possibility of falling would increase greatly.
And standing on the uncovered ice field, you can clearly feel the heat from your body being taken away. Even though the amount of exercise is not much, the physical energy consumption is not small at all.
"In polar regions, it's important to cover your entire body to protect against cold temperatures and strong winds, especially your head and feet, and don't stop."
"We have a reserve energy in our body, which is fat. By consuming fat, we can also generate calories. So I have been eating high-calorie foods these days, drinking milk tea as water, eating donuts as meals, and using cheese as seasoning, just to gain weight."
[Hiss, I was thinking, I vaguely feel that Lao Fang has gained a lot of weight]
[My goodness, this food... one meal will make you gain 10 pounds]
Bifang exhaled, but felt no warmth on his face.
The sun's rays raised the temperature a lot, to about minus thirty-five degrees Celsius, but it was still very cold. The huge temperature difference was like a giant water pump, sucking out all the heat with full power.
"The best way is to keep moving, which can ensure blood circulation and avoid sweating caused by excessive exercise."
"If you start to sweat, be sure to loosen your clothes and ventilate them in time. If they are soaked with sweat, the warmth-retaining effect will be reduced. At the same time, be sure to keep your clothes clean. Dust and grease will clog the gaps in your clothes and reduce the effect of isolating cold air."
After walking for nearly four hours, there was still nothing around.
Bifang stopped where he was and looked around. The sun had already reached its highest point, but it was still very low, as if it could not rise. It felt as if 30 degrees was already high enough in the past.
"We can't go any further. The ice field is bigger than I thought. It may take more than two days, maybe three. We should stop now while the temperature is still high and prepare for the night."
The width of the ice field is even greater than Bifang had imagined. The sea ice melts in summer every year and begins to freeze in autumn. But it seems that the sea ice is freezing very quickly this year, and perhaps this winter will be even colder.
"The weather today is actually very good. Look, the air visibility is very high." Bifang pointed around.
Indeed, the air here is eerily clean, except that it is as cold as a knife. The sea ice is endless, spreading all over is light blue and pure white, and the warm yellow sunlight.
The world is simple and elegant.
"If you are forced, such as in a plane crash, or other reasons to reach the situation I am in now, then this is the best time to call for help. The skills in this regard are similar to those in mountain rescue."
"Bright colors and linear shapes are easier to spot from the air. Even a piece of black clothing spread on a snowy ground with no grass can be seen from a long distance."
"Burning animal fat creates smoke. You can also use the ashes and burning debris to mark snow and ice, so don't skimp on your expensive calfskin belt."
"Search and rescue flights can only be carried out in guaranteed good weather conditions, so you have to be prepared. A helicopter is unlikely to come to your rescue in a snowstorm unless you have the daughter of a Fortune 500 entrepreneur on your team."
Bifang made a joke. He still remembers that during his second live broadcast, someone questioned the unreasonable rescue speed and said it was a staged drama.
In fact, it can only be said that these people do not understand the wilderness and human power.
"For snow rescue, most of the time, airplanes with sleds are used. There are not many of these airplanes in the world, so you need to find a place to use as a runway for landing. This place does not have to be very flat, but there must be no obvious objects that may damage the aircraft."
"The larger and harder wavy snow formed by the wind, commonly known as 'snow ridges', are not suitable for landing. The horizontal ground about 100 meters long and covered with a thin layer of snow is the most ideal landing site. This place will also be a good place for us to stay because we can spot the approaching polar bears at a glance."
Bifang squatted down, started to chop the ice with a knife, and said.
"Contrary to what many people think, polar bears' hair is not actually white, and their skin is even black. The reason they look white is because they have two layers of hair. The outer layer is about 5-15 centimeters long and is made of a protein called keratin. The middle is hollow rather than solid."
"This unique structure can receive sunlight and store it in the hollow hair. After being refracted at a certain angle, the polar bear's hair will look pure white, making it very difficult to find in the snow, and almost identical to the surrounding environment."
Therefore, a flat and open environment around it is very necessary so that the existence of the behemoth can be seen at a glance.
"This is because the hollow wool is waterproof and heat-insulating, which is equivalent to the onion dressing method we use, which can meet the needs of mimicry while keeping warm."
Bifang has also mentioned the onion dressing method before, that is, compared with thick clothes, multiple thin clothes of the same thickness will be more warm. A thin air layer is formed between the clothes, which has the effect of blocking heat loss.
It is also easy to put on and take off, so it can be used in different environments.
For example, if Bifang is going to build a shelter next and the amount of exercise is a bit high, he can take off a layer to avoid sweating.
As Bifang moved forward, the snow on the ground began to accumulate. This was good news, indicating that he was getting closer to land.
"I've always said that one of the keys to survival is knowing where you are. Once you know where you are, you can be prepared for a lot of things."
"Greenland is located at a high latitude, has a high average altitude, and is covered by glaciers, which results in a cold high pressure area on Greenland all year round. The cold high pressure area keeps the temperature low, and the cold currents surrounding Greenland further promote the cooling effect."
"But do you remember Svalbard? It is located at a higher latitude, but the temperature is very warm. This is because the warm and humid air currents from the Atlantic Ocean are very strong, which brings abundant . The warm and humid air currents from the Atlantic Ocean reach their peak in winter and are very strong."
"When the two collide, it becomes the most common cold and warm front system in geography textbooks, except that it doesn't rain, but snows, so there are many blizzards in Greenland."
"But Greenland itself is surrounded by cold currents, and due to the terrain, it is impossible to penetrate directly. Snow will only replenish the ice sheet to a certain extent in the marginal areas in autumn and winter, when the sea surface begins to freeze and continues to spread outward."
