A big country of aerospace with black technology

"Boom!"

A thunder on the ground sounded on the edge of the Gobi.

What followed was the falling spring rain.

People say that spring rain is as precious as oil.

In this place where the annual rainfall is less than 30 mm.

The value of spring rain is higher than anything else.

"The pilot's skills are not bad!"

Zhang Xingyang stood at the door of the tent with some joy, watching the rain falling from the sky.

"Under such conditions, the rain-enhancing agent can be spread evenly."

"That's right, Lao Yu was a labor model in our county back then."

The young man standing next to Zhang Xingyang said with pride.

"I think back then, Lao Yu flew a pesticide plane alone and sprayed hundreds of hectares of forest without wasting any time."

Actually, let’s talk about flight driving skills.

Compared with the many super pilots and test pilots Zhang Xingyang had seen before, Lao Yu's flying skills could only be said to be average.

But Zhang Xingyang never thought of comparing these people with Lao Yu.

"That's really a big deal." Zhang Xingyang said sincerely.

"After this rain, how many of the saplings we planted before do you think will survive?"

Raindrops as thin as ox hair slowly covered Zhang Xingyang's hair.

It made him seem to have a head of beautiful hair.

The young man combined his experience from childhood to adulthood and said with some uncertainty:

"It should be 60 to 70 percent?"

"We've never seen such well-timed rain before."

In fact, it is a pleasure for them to be able to water some saplings when planting them.

Not to mention a moderate rain falling directly from the sky.

In non-Gobi desert areas, when planting trees, you basically just pull a water pipe and flood the saplings.

I don't care so much about rainy weather.

Even if there is no water in the surrounding rivers and ponds, you can drill wells directly to water the trees.

But in this Gobi desert with many moving sand dunes.

Not to mention rivers and ponds, even if you want to dig a well.

Even if you want to drill a deep well, the drill bit can only hit rocks hundreds of meters down.

The rain gradually became heavier, changing from a drizzle to a light drizzle.

"This rain will continue for about six more hours."

Zhang Xingyang made some calculations based on the data he knew.

The young man didn't think much and just nodded.

He thought Zhang Xingyang got the results from a supercomputer in other places.

After all, their local small county didn’t even have a supercomputer that was several generations behind, let alone a supercomputer.

This is not surprising, after all, the local weather has been stable for a long time.

Of the 365 days in a year, 300 are sunny.

There are only a handful of cloudy and rainy days in the year.

There is no use in asking for a supercomputer.

Zhang Xingyang returned to his big tent, sat on a simple bench, and made himself a cup of strong tea.

Then I started thinking about the civilian use of microwave weather weapons.

There is nothing on the table in front of me except local weather data.

All important data is recorded in his own mind.

"Judging from the current situation, the application of rain cloud regulation is very successful."

Zhang Xingyang was thinking in his heart while tapping his fingers on the table.

"In this way, many projects can be adjusted."

"The most affected one is the hydropower station project."

Domestic hydropower stations basically rely on the weather for their livelihood.

Of course, hydropower stations all over the world look pretty much the same.

During the flood season, the electricity generated is so much that it cannot be sold.

During the dry season, the hydraulic turbine cannot even move.

This is also an important reason why although hydropower is good, everyone’s development efforts are not particularly large.

The fluctuations are simply too great.

In fact, all new energy power generation has more or less various problems.

Hydropower is seriously affected by river flood seasons, wind power is greatly affected by different wind directions in different seasons, and photovoltaic power generation is mainly affected by the timing of sunlight.

As for the more niche tidal energy and geothermal energy, the shortcomings are even more obvious.

So in order to use these energy more efficiently.

Various countries have developed various technologies.

In terms of hydropower, excess electricity is used during the flood season to pump large amounts of water into water storage stations, and then the water from these water storage stations is used to generate electricity during the dry season.

That is, a hydroelectric storage power station.

In terms of optoelectronics, hot molten salt power stations and space power stations have been developed.

"Maybe we can recreate the Lop Nur we once were."

Zhang Xingyang thought of Lop Nur, which is not far from here.

It was also a land of abundant water and grass.

In ancient times, it had many names, such as Youze, Yanze, Puchanghai, Furihai, Laolanhai, Linhai, Luopuchi, and Yuyuerhai. .

In the 1970s, there were still hundreds of square kilometers of water area.

But as the Tarim River dried up, Lop Nur disappeared from everyone's sight along with those ancient countries that had passed away.

"But if we want to recreate the basin of the Tarim River here, how many cloud systems are needed?"

Zhang Xingyang frowned slightly and started thinking.

This is a relatively complex issue.

Because there are many reasons for the disappearance of the Tarim River, in addition to local climate change.

The influence of human activities is also important.

As the number of settlements on both sides of the Tarim River Basin increased, residents began to divert large amounts of water to the Tarim River to irrigate farmland and meet residents' domestic needs.

The water used for domestic use by millions of people has greatly reduced the runoff of the Tarim River.

"This is going to be a long-term project."

"It will take at least several weeks of continuous rainfall to refill the old channel of the Tarim River."

"However, this may have unpredictable consequences for agriculture on both sides of the river."

Zhang Xingyang was one of the few who felt the difficulty of making a choice.

"It's better to leave it to the decision-makers to think about how to coordinate the contradictions between them."

"The next development of technology will mainly focus on temperature regulation."

Zhang Xingyang put the worries behind him and began to think about the development of microwave meteorological technology.

The main principle of adjusting the weather through microwave technology is temperature control.

Temperature can be said to determine most atmospheric activities on the earth.

The strength of the wind depends on the temperature differences between regions.

The size and amount of water in the cloud system also depend on the evaporation of oceans and lakes.

Evaporation is positively related to temperature.

"Urban fever in big cities is becoming more and more serious, and if not addressed, it will cause unimaginable consequences in the future."

Zhang Xingyang looked at the rain outside the window and thought about the big cities thousands of miles away.

Urban fever in big cities is a vicious cycle.

Relying on previous technology is basically unsolvable.

Office buildings, shopping malls, and residential buildings in cities use a large number of air-conditioning equipment.

It brings a lot of heat to city streets, causing the temperature on the streets to get hotter year by year.

It almost forces the crowd to escape into air-conditioned areas in the summer heat.

The cycle goes back and forth.

Decades later, there were even sightings of city streets with temperatures exceeding 60 degrees!

Breaking an egg on the asphalt road can really fry the egg!

At its worst, it was so hot that people died on the street.

In the past, hot death was just a common word spoken by everyone.

It’s rare to actually see someone being killed by heat.

"How did they solve this problem before real weather controllers came along?"

Zhang Xingyang began to search for previous solutions in his mind.

In his time, weather had become a product of artificial control.

Although it cannot be as detailed as every drop of rain, it can still control every square meter of rain clouds.

"Sure enough, it will still fall on the wind."

After looking up previous solutions, Zhang Xingyang thought.

As we all know, because of the urban heat island effect.

Generally, hot air blows from the city to the surrounding countryside.

And the solution for the future is simple.

That is to create enough temperature differences around the city to create cool breezes blowing towards the city.

However, this technology also has application limitations.

It can only be applied to cities built next to huge water systems.

For example, cities along rivers and coastal cities.

Because if this technology is used in a terrestrial environment, it will have a considerable impact on the land.

The impact of water bodies is much smaller.

Zhang Xingyang hasn't figured out how to solve the technical problems.

The young man rushed in with wet hair.

"Is something wrong?"

Zhang Xingyang looked at the other party with an unkind expression.

There are many confidential documents in his tent.

If the other party breaks in directly like this, it can actually be regarded as spying on secrets.

"rain"

The young man said breathlessly:

"The rain has stopped!"

Zhang Xingyang stood up and walked out of the tent.

It's only been an hour since it started raining.

Logically speaking, it shouldn't stop so soon.

Zhang Xingyang walked out of the tent and realized why the rain stopped.

The cloud is gone!

"Where's my cloud?"

Zhang Xingyang couldn't help but think:

"I have such a big cumulonimbus cloud here, why is it missing?"

This cumulonimbus cloud came all the way from thousands of kilometers away.

It proves that the cloud cover itself is sufficient.

It is impossible to disappear in such a short period of time.

Zhang Xingyang didn't say much to the people around him, and went directly back to his tent to make a phone call.

"Look at the satellite cloud map now. Where is the cloud cluster No. 4 that we brought here before?"

The researcher opposite was obviously a little confused by this glaring question.

But he still reacted quickly.

"Let me see, give me a minute."

Zhang Xingyang didn't say anything more and waited quietly for a minute.

"Dean, that cloud is now 60 kilometers northwest of you."

"Don't you always pay attention to its location?"

After Zhang Xingyang got the answer, he said with some dissatisfaction:

"Didn't I ask you to fix it in one place?"

"Dean, our microwave power satellites have been busy supplying power to foreign orders recently, and we don't have that many spare satellites at the moment."

After Zhang Xingyang got the answer, he felt helpless.

For current power satellites, their job is to provide power to the ground.

Microwave meteorological use is only its secondary use.

"It is better to meet the meteorological purpose as much as possible while meeting the power supply."

Zhang Xingyang was slow for a while before speaking.

The insufficient number of satellites is indeed the biggest problem they currently face.

Although more than half a year has passed.

However, the number of satellites in space still has not exceeded 100.

Just supplying domestic and foreign electricity is already a bit reluctant.

Not to mention, part of it can be used for microwave meteorology.

After hanging up the phone, Zhang Xingyang walked out of the tent.

"It only rained for an hour. Will it have a big impact on the survival rate of the saplings?"

Zhang Xingyang turned sideways and said to the young man beside him.

"The amount of precipitation in just one hour has reached 15 millimeters."

The young man revealed a statistic and said:

"It's enough for the Haloxylon ammodendron tree to survive."

"It's just that our reservoir water storage hasn't increased much."

The reason why it rains for six hours is to store more water in the reservoir that is almost bottoming out.

"The rainfall this time is not satisfactory, and I will give you a hearty rain next time."

Zhang Xingyang looked at the other party's eyes seriously and said.

The young man smiled and said: "We are very happy to have such a rain, and we don't dare to expect too much."

Then he changed the topic: "Let's go to the nearby Haloxylon ammodendron forest and take a look at the saplings just planted a few days ago."

The place where the trees were planted was not very far from their station.

It was also covered by the rain clouds just now.

I would imagine that those Haloxylon ammodendrons that have multiplied tenaciously in the desert by the tens of thousands could seize this opportunity and store enough water for themselves to grow.

Several jeeps were speeding through the Gobi Desert where it had just rained.

There is no mud that is common in plain areas.

There are only small streams of water flowing in a few gullies.

Upon seeing this, Zhang Xingyang thought: "The problem in the Gobi is far more than just precipitation. The soil is also a big problem."

If it is a small soil problem, there are actually solutions to it with modern technology.

But here is tens of thousands of square kilometers of land, and the means they can use are extremely small given the amount of land.

Here, the relationship between soil, vegetation and rainwater is intricate.

Changes in any one item will cause changes in the other two items.

In less than twenty minutes, everyone arrived at the Haloxylon ammodendron forest that had just been planted a few days ago.

The slightly yellow Haloxylon ammodendron sways on the Gobi desert after the rain.

There are still drops of rain and dew hanging on the tender green branches.

"It looks like these Haloxylon ammodendrons are doing fine."

Zhang Xingyang looked at the Haloxylon ammodendron bushes all over the ground with a happy face.

The Haloxylon ammodendron that stretched for several kilometers had already absorbed enough water.

It looked healthier than the Haloxylon ammodendron that Zhang Xingyang saw a few days ago that had almost turned into dry wood.

The young man also said happily: "It seems that of the 30,000 Haloxylon ammodendron trees planted this time, at least half will survive!" (End of Chapter)
