"Huh, luckily I gave you a look, otherwise something would have really happened."
The camera director wiped the sweat from his forehead and took a long breath. Fortunately, the guy didn't eat it, otherwise there would have been a live broadcast accident.
Just now, the program team confirmed that the mushroom the contestants wanted to swallow was the Death Angel Mushroom. In an instant, everyone was convinced by Bi Fang.
Not everyone has the ability to instantly identify poisonous mushrooms that are easily confused with just one glance.
What a reassuring consultant!
The eliminated person had nothing to say and allowed the helicopter to take him out of the Rocky Mountains.
"It's my job in the first place." Bi Fang waved his hand, indicating that it was not worth mentioning. As a safety consultant, he had the responsibility to avoid danger.
A false alarm.
The supervision team became even more concerned about the contestants and strictly guarded them, fearing that they would swallow some weird things again.
[Oh my god, I found something and I can’t eat it. It feels even more dangerous.]
[Mr. Que, fortunately I have Lao Fang, otherwise I wouldn’t have burped? 】
[But will mushrooms grow in this kind of weather? 】
"Yes, many mushrooms will grow in winter, but I was a little surprised that the Death Angel Mushroom appeared." The audience's question reminded Bi Fang.
Logically speaking, the death angel mushroom should only appear around April. It is not impossible for the mushroom to grow a month earlier, but was the temperature so high in these two days?
Bi Fang glanced at the thermometer and found that the temperature actually reached about ten degrees.
Two nights ago, the temperature still dropped below freezing!
Even if the temperature gets warmer during the day, it's still about 5 or 6 degrees Celsius, and actually reaches 10 degrees Celsius!
"Foehn?"
Rubbing his chin, Bi Fang had a vague guess. The Rocky Mountains were close to a cold current. There shouldn't be such temperatures in late February and early March. The only explanation was the occurrence of foehn winds!
Pang Di heard Bifang's mumbling and asked curiously: "Foehn Feng, what is that?"
"A strange weather phenomenon in the Rocky Mountain region of North America."
When someone asked about it, Bi Fang also explained it to the audience who heard it.
The Rocky Mountains were formed due to the intense collision and extrusion between the American Plate and the Pacific Plate. They trend northwest to southeast and are basically parallel to the western coastline of North America.
The area selected for the competition is located north of 50° north latitude. From the perspective of air pressure and wind belts, this area is controlled by the prevailing westerly winds all year round.
In winter, it is more affected by the cold air from the Arctic Ocean, resulting in low temperatures and snowy weather.
As winter ends and the climate slowly warms up, the high pressure on the North American continent will begin to weaken, and the cold air from the Arctic Ocean will also gradually weaken. On the contrary, the prevailing westerly belt from the Pacific will begin to affect this region.
Due to the obstruction of the mountains, the warm and moist westerly winds are strongly lifted by the terrain, forming abundant orographic rain. After passing over the tall Rocky Mountains, on the east side of the Rocky Mountains, the airflow contains less water vapor and flows downward along the slopes.
Do sinking exercises.
As the altitude continues to decrease, the air temperature continues to increase, turning into a dry and warm "Foehn wind" in the foothills.
The foehn phenomenon occurs in many areas of the world, including the Alps, the Greater Caucasus Mountains at the junction of Asia and Europe, and the Andes Mountains of South America.
"It would be fine if it brought water vapor. The evaporation of water will take away a lot of heat. However, because of the blocking of the mountains, the water vapor is blocked, leaving only hot and dry winds. During this period, the temperature in the Rocky Mountains will rise very fast, like a huge
If the heater blows towards the ground, the large amount of snow originally formed by the cold air from the Arctic Ocean will melt quickly.
You see, there was still some snow on the ground two days ago, but today it is gone."
After the program team heard about it, they immediately called up the images from the previous two days for comparison. No one noticed it before, but now it turned out to be true.
The forest floor was covered with a layer of white snow the day before yesterday, but now it has all melted away, exposing dark brown soil, which may turn green soon.
Is it melting too quickly?
Generally speaking, the thicker the snow, the longer it will take to melt it in spring.
Not to mention the wilderness, even in the city, a heavy snowfall by chance would take nearly a week to completely melt away, but now this scene happened in less than two days.
"Because of the foehn wind, every spring, as long as warm wind blows, the snow with a thickness of more than 10 centimeters will quickly melt within a day. The snow melts, the earth quickly returns to spring, and many mushrooms will grow in advance. This weather phenomenon,
Helping local production, so locals call this warm air flow "Snow Eater"."
[What an image name, Snow Eater, Cowhide]
[No wonder the Death Angel Mushrooms have grown out. We don’t have mushrooms here until April]
Many viewers said it was an eye-opener and they had never heard of such a weather phenomenon before.
However, Pang Di was a little confused. Will the rapid warming of the climate caused by the foehn winds have any impact?
"As the temperature warms up, will brown bears wake up early?"
"Um……"
Bi Fang lowered his head and pondered, and then nodded after a long while.
"This possibility cannot be ruled out."
audience:"!"
Lack of food is the main reason why animals hibernate. If there is enough food, many bears will not even hibernate.
"But the probability is still relatively small. Survival in the wilderness is inherently dangerous. All kinds of dangers exist objectively. The contestants know it in their hearts. Do you still want to give up recording because of this?"
Seeing Pang Di's worry, Bi Fang comforted him a little.
Those wilderness survival programs in previous lives couldn't have been abandoned just because there were bears in the wild, so what's the point?
What you want is realism. Could it be that the places Mr. Bei went to were filmed after the show crew captured Bear, Tiger and Wolf?
It must be impossible.
That was due to choking.
Bi Fang patted Pang Di on the shoulder: "Okay, don't think so much. All we can do is ensure the safety of the players as much as possible, and go back to recording."
"OK."
Pang Di nodded, that's all he said, so that's all.
The competition among contestants continues. Bono, who set out first, has even walked nearly 70 kilometers from the launch point, far ahead of the other contestants.
Mu Jalun, who was the last to set out, was not to be outdone. After eating food, he was full of energy and reached a speed of seven kilometers per hour. He also took some detours on the way, apparently discovering something.
The only female contestant also made a discovery, a cave.
Ava stared excitedly at the cave not far away, waving to Lisa: "Hey, Lisa, come and take a look!"
"cave?"
Lisa was a little surprised, then excited.
For two days, they had not caught any prey except some lichen and earthworms. What was in this cave that they suddenly discovered?
【Have you got lunch yet?】
【What's in the cave? A python?】
[Feels like a rat hole?]
[Fang Shen, tell me quickly, what’s in this? 】
The forest is rich in species, and there are many animals that can dig holes, but when you think of local species, combined with the size of the hole...
Bi Fang stared at the hole that was no wider than the palm of his hand for a while, and said suspiciously: "It looks a bit like a prairie dog hole?"
Prairie dogs?
What is that?
"That's the groundhog."
[Groundhog? You told me earlier, I am familiar with this one!!!!]
[Damn! There is a picture]
【Is it that!! Groundhog?】
Bi Fang nodded and explained: "There are many prairie dogs in the Rocky Mountains. They usually live in grasslands with relatively low altitudes. This coincides with the duo's route. They have to pass through forests and grasslands."
"And prairie dogs do not hibernate. They are accustomed to living in groups. They are highly social animals. They like to be active during the day and are good at digging holes. If it is really a prairie dog hole, it means that there is a large group of prairie dogs here, at least six or more!
"
Six!
The audience's breath suddenly froze when they thought of the plump appearance of the prairie dog.
You can eat it for a long time!
The duo didn't expect this. They didn't know what was in the cave yet, but they were still happy. Just looking at the size of the cave, they knew that the animals inside were not too small, at least enough for the two of them to need for a day.
Thinking of having food to eat, the two were very motivated. After a brief discussion, they immediately divided the work and cooperated. Ava went to search for bushes and branches, while Lisa, a member of the Berets, searched for other caves nearby.
Seeing Lisa blocking the newly discovered mouse hole, Bi Fang couldn't help but nodded: "It's a very correct decision. Many animals that are good at digging holes have multiple escape routes. If you only catch one hole guard, you will probably get nothing.
You must search around to see if there are other holes and block them all.
Marmots are experts at digging holes. They have a basically independent tunnel system, which can be dug up to 5 meters deep. The entrance of the hole will be hammered higher than the ground to prevent water from entering. There will also be a refuge room nearby for when enemies appear.
There will be storage rooms, living rooms, toilets, etc. further down. Generally, there is a main nest covered with soft straw mats at the end of the tunnel, and the infrastructure is quite complete.
In addition, Ava is also particular about the branches she finds. Her purpose is probably to burn the plants and use smoke to smoke out the animals in the cave, so all she collects are fresh branches broken off from the trees. Such branches have a high moisture content.
It also produces more smoke when burned."
[Groundhog: Shivering, the outside world is so scary]
[Both grass and groundhogs live more comfortably than me!]
[Wori, this quality of life is higher than mine. I have been working for three years and now I can’t even afford a toilet. I’m so impressed]
【Who is not?】
When Bi Fang introduced the luxurious residence of the groundhog, many people showed envy.
But when I think about them being eaten soon, I feel inexplicably relieved.
Bi Fang couldn't help laughing and said: "Don't say that, although prairie dogs are also rodents, they are natural fertilizers. They can continuously prune the grassland, increase the protein content of the grassland and the decomposition capacity of grass, and have a negative impact on the environment.
It’s very protective.”
While talking, Lisa had blocked all the holes she could find with stones, and Ava also used yesterday's charcoal fire to rekindle the fire.
In ten minutes, Ava lit the fire and put the branches and shrubs she had collected into it. The branches quickly twisted and deformed under the high temperature, creating a large amount of white mist.
Upon seeing this, Ava quickly stuffed the bush into the hole, took off her coat and stood in front of the fire, filling the hole with white smoke.
The white smoke had no way to go and could only drift into the cave, quickly filling the entire crypt.
Lisa held the spear in her hand tightly, waiting for the animal to emerge from the hole, and then stabbed it quickly.
Soon, rustling sounds came from the cave, followed by a slightly harsh scream.
"coming!"
Lisa was very excited. There was really something in the hole!
