Qianjiang's news reporter, schwyn, ho
Starting today afternoon (25 august), there will be more rain or thunderstorms in hangzhou, with successive high temperatures slowing down。
The hourly journalist learned from the meteorological services that this afternoon, with the exception of the main city of hangzhou and xiaoshan, the other counties and cities of hangzhou were required to carry out manual rain work. The meteorological authorities have explained why the heat of the previous period has not increased and it is only now。
Now, several meteorological offices are ready. The hourly journalists split up, followed by the yuhang regional meteorological department and the fuyang regional meteorological department, respectively, to record the full process of artificial rainfall。
Yuhang:
Let's go! Ten rain rockets are in place
In the middle of the day, there has been drought in some parts of the mountainous region of hang-wan, and tea farmers reflect the drying up of some of the young tea seedlings。
In the afternoon of today (25 august), the meteorology department of yuhang region planned to carry out artificial rainfall for a hundred cents, and the staff arrived at the bottle kiln warehouse at 12:53 p. M. To pick up the equipment and load it。
Four male compatriot from the warehouse launched the artificial rain launcher, which weighs approximately 300 and 400 pounds, and joined forces to push it onto the pickup truck。
This manual rain operation resulted in the recovery of 10 eod rockets, which were detonated at high pressure and were normally stored in blastproof boxes. The ammunition was removed and loaded into a wooden box with white foam on the vehicle。
When the equipment is loaded, everyone wears a helmet and wears his or her work clothes。
At 1. 12 p. M., a car was packed and sent to the point of work。
At 1. 58 p. M., the hourly journalist arrived with the rest of the station。
At a hilltop high at the fish and rock tunnel in the mackerel village, staff began preparations。
In the heat of the sun, a tripod was set up to monitor the opening of the decomposition launcher, and wooden boxes equipped with blast-resistant rain rockets were placed in a cool shade。
The transmitter, which was placed on a 30-metre ramp of rock, was being debugged。
At 14:17 p. M., the sky, which was so hot, suddenly began to sink, and in the hot air of the bamboo forest, the cold wind came。
Although there is a thick grey cloud over the small slopes on the side, based on observations, staff say that, for the time being, the sky along the point of operation does not meet the operational requirements of artificial rainfall。
In general, the cloud layer of artificial rainfall requires a certain thickness and vapour content, which should not be too high。
On-site, staff will be able to view the data through meteorological radar monitoring. The current cloud along the operational site is too high to be operational, and you will need to wait patiently for some time to see it。
As of 16 p. M. On the same day, staff were waiting。
Fu-yang:
Starting today, artificial rain will last a week
Since 1 august, the cumulative precipitation of the rich sun has been only 22. 5 mm (based on urban stations). Only one day on 4 august saw rain。
To mitigate the drought, increase reservoir storage and reduce the level of forest fire risk, fuyang decided to implement artificial rain surge operations from 25 to 31 august。
There are three alternative sites for operation: fukuyang-1 (fuchun street, spring hua village sharpening knife reservoir); fukuyang-2 (shangwon rock ridge reservoir); and fuyang-5 (sliding base, yong an hill, chang an)。
On 25 august, at 1:30 p. M., hourly journalists arrived at point 5 on the same day, the glidering base at yong an hill, and discovered that the rain surge was ready。
At the scene, the staff of the fouyang regional meteorological department reported their location to the hangzhou city meteorological department, which will keep a watch on the meteorological radar return to the wave map, inform the cloud in a timely manner and alert the field to the response。
The bl-1a artificial rain-added rocket was used today. The range was 8,000 metres and the impact of one rocket could be as high as 10 square kilometres. Each rocket body has a unique code and can trace its origin and destination on a platform reserved to the department of provincial meteorology。
Artificial rainfall is defined as the artificial supplementation of certain necessary conditions for the formation of precipitation in accordance with the principles of natural precipitation, which promotes the rapid condensation or touching of clouds and increases them to raindrops and land to the ground. This is done by selecting the right time, depending on the physical characteristics of the different clouds, to sow dry ice, silver iodide, salt powder and other catalysts from aircraft and rockets into the clouds, so as to bring or increase precipitation。
The effective ingredient of today's rain-added rockets is silver iodization。
Why is the model number of the artificial rain-added rocket different
"the difference in numbering is due to different manufacturers, different specifications and different methods of recovery. The staff member explained。
At 14 p. M., journalists followed the staff members' heads and found only a few twilight clouds floating over their heads。
The deputy director-general of the meteorological department of the fuyang district, lau su-fung, said that the presence of mount yong-ahn in the mountains, combined with the impact of clouds on the outskirts of today's typhoons, was relatively ripe for rainfall, but that it was possible to meet the conditions for increased rainfall, depending on subsequent cloud maps。
The red orange is the rain cloud。
For now, everyone is waiting。
There are high requirements for standardization in manual rain surge operations. Wireless surveillance is to be installed at every point of operation。
Three operational points and scope of impact
At 14. 30 p. M., journalists stood at the top of mount yong an and found a thick cloud in the west。
It's like it's already raining。
That's what we're waiting for, and that's what the rain makes the clouds。
At 14. 35 p. M., the loading started。
Half of the sky along mount yong-ahn is covered with clouds, and the sun hides in the clouds, and the top of the mountain is cool and practiced。
The rain-raising operators at the scene were encouraged: “the conditions today are good and should bring a good rain to fuyang”
At 14:58 p. M., with a single order, four rockets were launched。
Second load launch。
It was about 10 seconds after the launch that the sound of the silent explosion came from the clouds. Ten rockets were launched today, all of which were successful。
“when rain-added rockets explode, they will be split into countless fragments, not more than 10 grams per piece, without harm to the ground.” according to staff, some of the larger types of ammunition were recycled using self-recovered parachutes: rockets were targeted at clouds above the top left of the location point. It's supposed to be raining under the clouds right now, and it'll come when the clouds come。
At about 3:10, the field work was completed。
