In the summer of 1958, 60 years of drought tested the land of jilin。
As a result of the drought, the capacity of the well-filled hydroelectric power plant affected the generation of electricity, and the supply of electricity to the north-east power grid was critical and seriously threatened the production of heavy industrial bases in the north-east。
On 18 july 1958, the chinese communist party provincial council, the provincial people's committees (known as the provincial human rights committees) and the jilin municipal councils and the municipal people's committees issued urgent instructions to mobilize the population against drought。
The director of the weather station in jilin province, dong hong-yun, and the forecaster, mu jia-hyu, saw a news in the science paintings and reference news that artificial rain was used abroad to solve the drought。
As a result, they boldly put forward their visions, following the example of abroad, to overcome drought by artificially influencing the weather。
Although no similar operation had taken place throughout the country at that time, the provincial meteorological service, after reporting to the unit, found the recommendations to be very good, immediately reported to the provincial council and the provincial commission on human rights and soon received approval from the provincial leadership。
Aeroplanes are needed for artificial rainfall, but where will they find it?
At that time, there were no civilian aircraft in jilin province, but only military aircraft. As a result of the communication with the province, there was finally a willingness to help coordinate the aircraft used for artificial rainfall. Subsequently, under the coordination of the ministry of industry of the provincial council, the chinese people's liberation army was able to provide an aircraft to support artificial rain。
The aircraft belonged to the bomber, but it had no place to sow catalysts. As a result of the study, it has been found that the abdomen of the aircraft are exactly two bombards, designed to fire artillery shells, and that, if modified, they could turn into transmitters. As a result, the force's repair plant was busy for a week and finally installed catalyst containers on the aircraft, which could be soaked through the launch pad corridor。
That is how the first artificial raining aircraft was born in jilin province。
Where's the catalyst for rain?
The newspapers say that artificial rain from abroad spreads dry ice by plane, but where does it come from?
It is understood that there is no single city in changchun。
As a result, the departmental meteorological service “takes lessons” from the central meteorological service。
After several breaks, the central meteorological service stated that it was their understanding that sodium chloride could also be replaced。
For this purpose, 200 kilograms of large grains of salt were procured。
After multiple contacts, all 200 kg of large grains of salt were crushed。
How far did it break?
Broken to the size of only micrometres, equivalent to one thousand millimeters。
There are planes, catalysts, waiting for the right weather。
On 21 july, according to weather forecasts from the provincial weather station, the central region of jilin will be affected by a weak precipitation weather process in jilin province. As a result, the provincial meteorological department and the troops providing the artificial rain-raising aircraft agreed to use the occasion to conduct the first artificial rain-raising experiment。
On 21 november, at 1520 hours, with tension and excitement, a modified sou-type “du-2” light bomber, driven by the director-general of an air school inspection zhou, took off from the main house airport with more than 200 kilograms of “big grain salt” and carried out a manual rain test along the changchun-changtian line。
One test was successful and did not make the earth completely quench its thirst。
In late july, drought continued in the province of jilin, with heavy flooding of hydroelectric plants and the urgent need for artificial rains to combat and respond to drought。
Summarizing the effects of the first test and verifying relevant information, it was found that the use of sodium chloride as a catalyst for artificial rainfall was corrosive and that the search for dry ice and silver iodide had to be expedited as a catalyst. As gilwood chemical could produce dry ice, the artificial rain increase test base was transferred to a section of the jilin city air force。
On the afternoon of 8 august 1958, the jilin river appeared with dense clouds and high clouds, and the province of jilin successfully used dry ice for artificial rainfall. The rainfall, which was about 20 kilometres long and 10 kilometres wide, was reported to be 16 mm by local hydrological stations。
As a result, 20 artificial rains have eased the drought on the outskirts of jilin city and in yongjie, the river, the river, the sea and the shuran, and have also released “dreary” water reservoirs。
