Li Hang looked at his watch, walked up to Song Zhihong and asked:
"It's been an hour, why hasn't it rained yet?"
Song Zhihong observed the changes in the clouds in the sky and said to himself:
"It shouldn't be, it should be raining...how could it be? Could it be that the water droplets contain too much DI elements? That shouldn't be the case either..."
"What did you say?" Hearing Song Zhihong mumble, Li Hang didn't hear clearly.
Song Zhihong said seriously: "Wait a little longer, it should be about to happen."
Li Hang crossed his hands on his chest and raised his head to look at the sky.
A few minutes later, he saw a black shadow coming towards him.
And as we got closer and closer to him, we could see more clearly.
It's raining, but why is it so heavy?
Bang!
A rainball about the size of a fist hit his head, and his hair was instantly soaked by the rainball.
"Whoops! Such big raindrops? No, rainballs!"
A rainball as big as a fist hit his head, giving him a headache.
Bang bang bang bang!
Countless rainballs fell from the clouds in the sky, ranging from the size of glass beads to the size of two fists.
Almost like hail.
Ta-ta-ta!
In the rain, some hailstones also fell together.
The smallest of these hailstones are as big as a fist, they hit the ground and shattered.
"Run!" Song Zhihong shouted to everyone after seeing the huge hail and rain falling.
Li Yu was right next to the door of the duty room. He reacted quickly and immediately got up and picked up his stool and walked to the duty room.
This rain was so unusual.
Hailstones the size of fists can already be called hailstones.
Generally, hailstones that fall before the apocalypse are no more than the size of mung beans, usually between 5 mm and 50 mm in diameter, but there are also larger hailstones that can reach more than 10 cm in diameter.
The size of hail that is falling now is a very large hail that is rarely seen before the end of the world.
In addition to hail, there were also fist-sized rainballs.
Each rainball was connected in a line, and the rain was very dense. Looking at the scene in front of him, Li Hang finally understood what pouring rain looked like.
This was more exaggerated than any rainstorm they had ever seen before!
Boom, boom, boom!
Ding-ding-ding-ding!
Huge hailstones hit the iron sheet of the crane at the construction site, making a crisp sound.
Even the roofs of some cars in the buffer city were hit by hail with small dents.
"not good."
Anya looked at the huge hailstones and asked Song Zhihong anxiously:
"Didn't you say it's raining? How come it's hailing? There's such big hail!"
Song Zhihong thought for a while and then said: "The rain bombs fired by the anti-aircraft guns have a height of more than 4,000 meters, and there is a chance of producing hail. What's wrong?"
Anya looked worriedly at the greenhouses in the buffer city and rolled her eyes at Song Zhihong.
"With such a big hail, I'm worried it will cause damage to the greenhouse!"
Li Yu frowned when he heard Anya say this from the side.
He stood up and walked over, "Song Zhihong, how long will it rain?"
"this......"
Song Zhihong clasped his thumb nails on his palms and said with some anxiety:
"This time it is just a test. Not many rain gas canisters are fired, but the cloud layer is too thick, and the effect of the tear gas canisters will be maximized. It is estimated that it will take one and a half to two hours."
"However, we launched the rain bombs in the west direction. We have delineated the test locations. The rainfall locations are mainly in the west and outside of the buffer city. There may also be some in the first outer city, but the inner city and the second, third, and fourth outer cities should be
Not affected..."
When Li Yu heard this, he immediately looked at Anya.
Understanding in seconds, Anya picked up the walkie-talkie to contact Li Peizhen and the others to confirm whether it would rain in the inner and outer city.
After Xiao Jun heard this, he moved a table directly, raised his hands above his head and walked out of the duty room.
Look in the direction of the inner city and the outer city.
Taking the first outer city as the dividing line, there was no rainfall in the inner city and several other outer cities, but the rain on their side was extremely exaggerated.
Rainballs mixed with hail struck the table above his head, crackling.
Hail fell from a high altitude and hit his hand holding the table leg.
It hurts!
At the same time, hailstones and huge rainballs knocked the table above his head upside down, and Xiao Jun hurriedly ran towards the duty room.
call--
After entering the duty room, he breathed a sigh of relief.
He said to the people who were looking at him: "Song Zhihong is right, there is no rain in the inner city and several outer cities, but there is hail rain in the front area."
At the same time, Anya also received news that Li Peizhen was staying in the inner city, and she breathed a sigh of relief.
fortunately.
Such large hail may cause damage to greenhouses and affect their food production.
However, the area in front is mainly a residential area. Although there is an agricultural production area next to it, the greenhouses affected are limited.
Moreover, they actually have experience in resisting hail before. The greenhouses use PVC solar panels. PVC materials have high impact resistance, are not easy to break, and can effectively resist external impact and damage.
If it were made of glass, it is estimated that such a large hail would directly smash holes in the greenhouse and destroy all the crops inside.
In addition to using PVC materials that are relatively resistant to damage, they also installed anti-hail nets on the roof of the greenhouse.
This anti-hail net is made of polyethylene material with added anti-aging agents.
Can resist and defend against hail.
Anya stood at the door of the duty room, staring closely in the direction of the greenhouse in Buffer City, observing the impact of hail on the greenhouse.
She was relieved when she saw that the greenhouse had withstood the attack of huge hailstones.
.......
In the crackling hail of rainballs,
The second uncle looked serious, pulled Song Zhihong aside and whispered:
"This hailstorm is different from the expected results you submitted before..."
Song Zhihong replied awkwardly:
"My problem is that we made a mistake in judgment, mainly..."
The second uncle did not listen to what he continued and interrupted:
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "It's not your problem alone, I should have let you do experiments outside..."
The second uncle blames himself a little, and he also bears some responsibility for this unexpected situation.
"in addition."
"Why do such big rainballs and hail fall?"
Song Zhihong thought for a moment and said:
"I think it may be because the water droplets in the clouds contain a large amount of DI elements, which makes them lighter. For raindrops to fall, they must have a large enough volume and mass...that's why rain and hail are so big.
volume."
The second uncle nodded thoughtfully, "Go back and make an experiment summary report, write down clearly the shortcomings of this experiment, and reflect on it carefully."
"Yes." Song Zhihong breathed a sigh of relief.
It's okay to write a self-criticism report, but fortunately there is no accountability.
........
.......
In this huge hailstorm, the construction workers and transportation personnel in the buffer city were also stunned.
Crash--
"You are risking your life by riding on the horse?" Gao Zhongtian threw down the iron plate on his head and cursed at the men next to him who were bruised and swollen by the hail.
"I...I didn't expect such hail." The man said aggrievedly as he touched his arm, which was bruised and bruised.
Gao Zhongtian said speechlessly:
"The radio has announced that we should stay indoors and not go out. Why do you have to go out so many times?"
"Brother Gao, don't be angry, I'm fine." The man with the mole on his nose smiled playfully and came to Gao Zhongtian's side and said.
Gao Zhongtian pointed his finger at him and became very angry.
"Still laughing? If I hadn't come to save you just now, what would you have done if you had been knocked unconscious?"
"Thanks to Brother Gao..."
Seeing that he was still smiling, Gao Zhongtian sighed and shook his head and said:
"A Bing, sooner or later you will die because of your recklessness. We have survived all these years. I don't want you to cause you to..." because of some small mistakes.
...
In the accommodation building next door.
Le Ziqing looked at the heavy rain and hail and was stunned.
"The rain must have been too heavy. It also hailed. It's really an exaggeration!"
Sergeant Luo raised his eyebrows and twitched his ears.
"We made a bet just now. You want to massage my shoulders and feet. Come on, give me a massage."
Le Ziqing's face was filled with disdain, "Tch! I didn't promise you just now."
"You want to default on your debt?" Master Luo looked at Le Ziqing.
Le Ziqing stretched out and said, "I didn't promise you just now! Stop being so sentimental."
He stretched and walked towards the accommodation room.
While saying:
"It's raining and hailing, so I don't have to go to work. I'll be called when the rain stops and I'll take a nap. They said it's raining now and I'll get sleepy easily."
far away.
Some people also chose to stay in their cars.
They heard the crackling sound on the roof of the car and regretted why they didn't go to the accommodation building.
"Brother Jie, can this big camphor tree base be able to create artificial natural disasters? It's really amazing." A green-haired man in the main driving position asked.
Snap!
The man in the co-pilot slapped Lu Mao on the head.
"Stupid, this is artificial rainfall!"
"Artificial rainfall, such a heavy hailstorm?"
Xia Jie opened the car window a little. Due to the rain outside, the temperature dropped obviously.
The cold air blowing in from the car window has a fresh smell.
"Lv Mao." Xia Jie suddenly said.
"Huh? What's wrong with Brother Jie?"
Xia Jie looked at the hail rain outside and said quietly:
"The depths here at Da Zhangshu Base are unfathomable. Let's not go anywhere else. It's good to stay here. Let's settle here in the future."
Lu Mao touched the green hair on the top of his head, "Okay, I will stay wherever Brother Jie stays."
Over the years, they have joined many forces, but the Great Zhangshu force is the most powerful and stable they have ever encountered.
Almost all the bases and forces they visited were destroyed.
The two of them seem to have bad luck, and they bring bad luck wherever they go.
Not long after joining a force base, that force's base perished due to various reasons.
The key point is that the base that was added was destroyed, and both of them were still fine. It has to be said that their lives were really serious.
Three months ago, they fled from the south and joined the Da Zhangshu base.
Since you can drive an excavator and build iron frames at high altitudes, you can get a lot of contribution points here. In addition to making a living, you can also save a lot of points.
The three months here at Da Zhangshu Base were the most stable three months since the end of their lives.
The hail rain fell for more than an hour and finally stopped at two o'clock in the afternoon.
It rained for more than an hour, and 400 millimeters fell, which was a super heavy rain.
Generally speaking, rainfall is defined as the depth of water falling to the ground within a certain period of time, usually measured in millimeters.
Example:
The meaning of 100 mm rainfall,
It means that when it rains 100 mm in one hour, it means that within this hour,
If there is a horizontal plane without penetration or evaporation, then the depth of the accumulated water layer on the plane will reach 100 mm, which is 10 cm.
For 400 mm of precipitation, it is 40 cm.
In just one hour, 400 millimeters of rain fell, which was truly terrifying.
The underground flood discharge pipes in the buffer city are now operating at full capacity, continuously transporting rainwater to the cliff lakes in the buffer city.
It had not rained for more than four months, and the lake in the buffer city was less than half full. Now it rained for an hour, and the water level suddenly increased.
Master Luo came down from upstairs and stepped on the ground where there was still a few centimeters of water deep.
While walking to collect water, he wanted to check the electric truck. He would have to go out to transport coal later.
It rained 40 centimeters deep in an hour, but it only stopped raining for less than two minutes.
There was only a few centimeters of rainwater left on the ground.
It has to be said that the flood drainage capacity of the Dazhangshu Base is extremely strong.
Xu Zhen, a professional underground drainage engineer, transformed the drainage above and below the Dazhangshu Base to an extremely exaggerated level.
In the apocalypse, heavy rains and natural disasters occur frequently, and the base does not have a good underground drainage system, which can easily lead to waterlogging disasters.
After many modifications, once there is heavy rain, all running water will automatically flow to the artificial lakes and reservoirs in the base.
After the artificial lakes and reservoirs are full, they will automatically open flood discharge channels to drain excess rainwater out to avoid internal waterlogging.
The rain stopped.
Li Yu and others also walked out of the duty room.
The clouds in the sky ahead were much thinner, and golden sunlight shone on the ground.
only......
The accumulated clouds on both sides rolled away at a speed visible to the naked eye towards the location in the middle where the rain bombs had been bombed.
Due to thermal expansion and contraction, they were able to use rain bombs to digest the water vapor in this cloud layer, but they could not prevent the cloud layers in other locations from squeezing in.
Artificial rainfall can only remove clouds in an area, and it is a temporary solution. It cannot solve the fundamental problem.
There are thick clouds all over the world, and rich water vapor condenses in the clouds.
From this point of view, artificial rainfall can only be used as a way to replenish water, but it cannot solve the problem of cloud squeezing.
But.
Li Yu and the others were a little frightened.
In just over an hour, 400 millimeters of rain fell in this area.
Really scary!
Looking at the accumulated clouds in the sky, the clouds on both sides in front slowly filled the gap in the middle.
Li Yu was a little worried. If all the water vapor in the clouds in the sky condensed and rained, how terrible would the falling rain be? How terrible a flood would be caused by so much rain?
