An artificial rainfall eggshell in Sichuan fell from the sky, rubbing the back of the passerby's head and falling to the ground, making the passers-by afraid! If it really hits people, whose responsibility is this?
Why can tools of artificial rainfall land in manned areas?
Generally speaking, before the artificial rainfall, the relevant staff will make full coordination preparations, which will take several days to carry out. They need to develop a work plan, report to the relevant authorities, and carefully select the launch direction to avoid the population activity area. Generally, after completing the task of rainfall, the eggshell will fall within ten kilometers of the launch site.
In fact, this is not the first time that the eggshells of artificial rain shells have fallen to areas inhabited. On the afternoon of July 28, 2022, Mr. Gu of Dezhou, Shandong Province, was busy in the courtyard, when suddenly a palm-sized object fell from the sky, and with a loud "bang", it landed at his feet. After being greatly frightened, he looked forward to see a metal eggshell printed with "Human Rain 5-04-12". Even a few days later, Mr. Gu recalled this matter or would be afraid, according to his recollection, that eggshell weighed less than a kilogram, fortunately did not hit people, otherwise now can not speak.
In addition to the eggshell, there are some fine pieces of eggshell around, but they are relatively small. According to Mr. Gu, a few days ago, when a villager in their village was working, there was also an eggshell that fell around him, but the volume was not large.
After the reporter called the local meteorological bureau to understand the situation, he confirmed that it was the eggshell of an artificial rain shell. The staff replied that the current launch of artificial rain shells is generally launched in the open area of unmanned people to a height of 5,000 meters, the general warhead will automatically shatter after the explosion, falling to the ground will not have an impact on people, but there will also be some unexpected situations, such as unbroken shells, such as this incident, this probability generally does not exceed 3%, so there is no need to worry too much.
As the saying goes, "not afraid of ten thousand, just in case", although the probability of this event is small, but there will still be a possibility, but science with the progress of the times and progress, I believe that with the passage of time, the technology of artificial rainfall will become more and more mature, the birth of new technology will bring a satisfactory answer to our question.
What is artificial rainfall? What does it look like?
In fact, the so-called artificial rain is not so mysterious, its essence is nothing more than a chemical action, that is, the work of putting dry rain inducer into the clouds.
In the specific operation of artificial weather influence, the target cloud layer is first locked by the integrated weather monitoring system using ground-based and space-based observation systems; Then the operation command center formulates a comprehensive operation plan, applies for operational airspace, and carries out artificial weather influence operations; Finally, the operation command center will test the effect of artificially influencing the weather operation.
Artificial rainstorms usually use modern detection equipment such as weather radar, sounding instruments, meteorological satellites, and detection operation aircraft to find out the basic weather environment, and then use aircraft, rockets, artillery, combustion furnaces and other transportation equipment to send catalysts into the clouds, so as to achieve the intervention goal of local regional rainfall, and the catalysts used mainly include refrigerants, hygroscopic catalysts and silver iodide.
The traditional way to deliver rain-inducing agents is nothing more than two, one is the aircraft sowing coolant or catalyst, and the other is firing a cannon or rocket into the clouds. New types include high-voltage electric technology, electrostatic catalytic artificial rainfall technology, etc. However, the most used shells are not high in cost and experienced. The head of the shell is a non-metallic shell, using very little explosives to blow out the rainjack, and an exploding shell can affect the range of tens of kilometers.
We all know that artificial rain can alleviate drought, but is it potentially harmful? Will it affect people's health and ecological balance? In particular, many middle-aged and elderly people will have a bad view of this. As mentioned above, the catalysts we are currently using are hygroscopic agents such as salt particles that can adsorb water in the cloud into larger water droplets; The second category is dry ice with a very low temperature; The third category is silver iodide, known as "nucleating agents."
Dry ice is the solid form of carbon dioxide, and it and the salt particles are derived from natural substances, so they have no impact on the environment. Silver iodide is currently the main catalyst for artificial weather influence in mainland China. The toxicity of silver iodide itself is very low, coupled with its efficiency is a hundred times higher than that of dry ice, so the total amount of silver iodide is also very small, and the content of silver iodide scattered in the sky is very low, completely within the standard range, and it is impossible to pollute the atmosphere and water sources. So this worry is completely unnecessary.
How exactly do you avoid this happening in the future?
At present, although the mainland's technology of artificially influencing weather is relatively mature and the practical experience is relatively rich, the corresponding administrative management system still needs to be sorted out and improved. In view of this incident, the mainland should strengthen the public's right to know, participate in and dispute resolution affecting the weather and improve the relevant management system.
The mainland's current legal system related to artificial weather influence does not fully stipulate the "public participation" system, so the current system should strengthen the public's right to know and participate in the protection. Specifically, the right of public participation includes the right to artificially affect weather legislation and policy proposals, the right to know artificially influencing weather operations, the right to participate in decision-making, the right to supervise and criticize, and the right to damage relief.
In particular, the relevant compensation and compensation system should be improved, and the state should compensate for accidents and safety accidents that may occur during the implementation of activities that artificially affect the weather.
Second, the mainland lacks a sound technical supervision mechanism. The mainland does not have uniform safety standards for all aspects of artificial rainfall, and technicians only implement artificial rainfall according to the arrangements of scientific and technological workers, and there is no clear concept of the risk problems caused by artificial rainfall technology.
However, the "tight integration" and "complex correlation" of various parts of the modern artificial rainfall technology system make some links in the technical system maintain a "close complex relationship", and this mutual influence usually occurs in a short period of time, due to the lack of corresponding management mechanisms in the mainland, making it difficult for scientific and technological workers to make full estimates of technological risks.
Therefore, in order to reduce the technical risks caused by the flood of artificial rainfall technology, the mainland must have a strict technical supervision mechanism, and once not enough attention is paid, more and more "accidents" like this incident will occur, and even cause greater disasters.
In the final analysis, the police station only recovered the eggshells and responded that it was indeed a tool for artificial rainfall, but it was impossible to distinguish which action it came from, and there was no meteorological bureau to claim the eggshells. Even if no harm is caused, accountability needs to be pursued and the reasons behind it need to be clarified. No casualties do not mean that there is no responsibility, the relevant departments must thoroughly analyze the cause of this incident, is it an accident or man-made? How exactly did the accident occur and what factors were involved? How do I fix it? Not only that, the mainland should also speed up the improvement of corresponding laws and regulations and improve the relevant compensation and compensation systems. The problem can only be solved if it is put in place. Only when the people's precious life and health are properly guaranteed can they be guaranteed.
