Seeding and verification of artificial extension or artificial target area {SEEDING AND VERIFICATION METHOD FOR TARGETTED CLOUD SEEDING}

The present invention relates to a method for seeding and verifying artificial extension or artificial snow target area, and more particularly, to a method for seeding and verifying artificial extension or artificial snow target area for generating artificial expansion or artificial rain phenomenon in a local area.

Population growth and economic development increase the demand for water resources, but given the limited availability of water resources, it is expected that water shortages will intensify in all regions over the long term. According to a survey by the Population Action International (PAI), a subsidiary of the United Nations (UN), Korea has 1520 tons of water per capita per year, with countries lacking water along with Libya, Morocco, Egypt and Oman. Are classified as

Korea's annual average precipitation is 1,310mm, which is higher than the global average precipitation, but the annual rainfall per capita is only 12.5% of the global average. In addition, in Korea, much of the average annual rainfall is concentrated in summer, and it is difficult to secure efficient water resources due to the severe seasonal variation of precipitation and the steep slope of river basins.

In particular, in Gangwon-do region, the annual average rainfall is 1,400 ~ 1,800㎜, but it is classified as a wet area. However, due to the seasonal and topographical influences, the rainfall is concentrated in the summer season and the winter precipitation is very small. Only 15%. Climatically, annual rainfall is less than 75% of the climate, drought; if less than 50%, drought is classified as drought area in winter and spring.

In situations where water resources from nature are limited, the only alternative would be artificial extension or hatch technology that could increase the supply of natural resources as a means of developing auxiliary water resources.

Here, artificial expansion or artificial rain clouds form a cloud layer, but when there are few ice tablets or condensation tubes in the atmosphere, and when the droplets cannot grow due to precipitation, artificially sprinkle artificial "Cloud Seeds" to rain on specific areas. It has been studied since 1946, and has been put into practical use in the United States and Russia, and technology development is in progress in over 40 countries.

Until recently, artificial expansion or artificial rain experiments using aircraft have been applied to artificial clouds in the cloud so as to cause precipitation in large areas, and artificial expansion or artificial rain seeding and verification techniques for specific target areas have not been developed yet. In this regard, the search for a solution is emerging as an important matter.

The present invention has been made to solve the above-mentioned problems, the purpose of which is to induce precipitation in the target area using the topographical features of the Taebaek mountain range and the direction and speed of the wind limited water resources, forest fire, etc. It provides a method of seeding and verification of artificial extension or artificial rain target areas that can contribute to reducing and preventing such weather disasters, providing leisure environment, power generation and cloud physics research using water resources.

In order to achieve the above object, the present invention includes the steps of: a) moving the artificial expansion or artificial storm target area to the wind; b) pre-spraying the cloud seeds on the wind upside of the target area in advance so as to reach after a set time when the weather conditions for the target area are satisfied; And c) verifying the effects of artificial expansion or snow storms with aviation radar and ground water concentration observation equipment from the seeding area to the target area; Characterized in that it comprises a.

In the step b) of the present invention, the cloud seeds are sprayed to intersect with the direction of the wind blowing from the top of the cloud or from the upside of the target area into the cloud.

In addition, the step b) in the present invention is characterized in that the cloud seed is carried out if the temperature of the spraying area is below minus 40 ℃ ~ minus 5 ℃.

In addition, in the step b) of the present invention, the cloud seed is characterized in that sprayed at less than 5km if the wind is less than 3m / s.

In addition, in the step b) of the present invention, the cloud seed is characterized in that sprayed before 10km if the wind is 3 ~ 6m / s.

In addition, in the present invention, the cloud seed spraying area in the step b) is characterized in that the 100㎢.

As described above, the seeding and verification method of the artificial extension or artificial rain target area can be limited to induce precipitation in the target area by using the geographic features of the Taebaek Mountain Range and the direction and speed of the wind. It has the effect of contributing to the reduction and prevention of the same meteorological disaster, the provision of leisure environment, the generation of electricity using water resources, and the study of cloud physics.

Hereinafter, with reference to the accompanying drawings, the artificial expansion or artificial rain target area seeding and verification method of the present invention will be described with reference to the embodiment as follows.

Seeding and verification method for artificial extension or artificial rain target area according to an embodiment of the present invention is a preparatory step (S10), the target area wind-side moving step (S20), cloud seed spraying as shown in Figs. Step (S30) and the step of verifying the effect of artificial expansion or artificial rain with the radar and ground water concentration observation equipment for aviation from the seeding area to the target area (S40).

Although the preparation step (S10) is not shown in the figure, the cloud seed spreader, silver iodide, liquid nitrogen, optical particle counter, radar, aviation GPS, hydraulic calculator, aviation walkie It is a step to prepare and check the back.

The target area wind-side moving step (S20) is a cloud seed spreading area for performing artificial expansion or artificial rain in an arbitrary target area (ski resort, etc.) in the inland (young west region) of Gangwon-do using an aircraft equipped with a cloud seed spreader. It is a step to move. At this time, the cloud seed spreading area is confirmed by aviation GPS, and the aircraft moving to the cloud seed spreading area is notified by the ground controller of the wind seed spraying altitude wind speed by the air radio. At this time, the spreading altitude of the cloud seeds depends on the cloud movement.

The cloud seed spraying step (S30) is artificially spraying the seeding material of the cloud seed mounted on the cloud seed spreader on the upper side of the target area when the weather conditions for the cloud seed spreading area are satisfied [in order to induce precipitation Iv) or artificial spraying of various particulate matter acting as a coagulation tuberculosis. The weather conditions in South Korea are based on air pressure arrangement (North and South Korea) and cloud seed spraying areas where high pressure is to the south and low pressure to the south. It is preferable to carry out when the clouds in the East Sea caused by the Dongfeng series (heavily wind) flow into the Taebaek Mountains in the temperature of below 40 ℃ and below -5 ℃.

In other words, the cloud seed spreading step (S30) is performed when the cloud flowing in the East Sea (Easterly Wind) rides through the Taebaek Mountain range and reaches the supersaturated state artificially on the cloud. It is a technique that induces snow (right) in the target area by spraying cloud seeds. At this time, unlike the plains, the northeast wind, which targets the clouds beyond the Taebaek Mountain range, increases the altitude and heat-insulates the air and increases the moisture in the clouds, but the cloud seeds become scarce. It is a condition, and the temperature of cloud seed spreading area is performed below minus 40 ℃ and below minus 5 ℃ to induce snowfall (right).

Eventually, when the cloud inflowed from the sea in the winter over the Taebaek Mountains and there is little Ice Nuclei or Cloud Condensation Nuclei in the supersaturated state, when the cloud cannot grow due to snowfall or rainfall, it is artificially used by aircraft. Cloud seeds, such as silver iodide (AgI), liquid nitrogen (LiN) or dry ice, are sprayed onto cloud tops or cloud penetrations. Therefore, it is possible to induce snowfall (right) by limiting to any target area inland while using the topographical features of the Taebaek Mountains and the wind direction and wind speed.

In particular, the area where the artificial-expanded flight test was carried out was the Yeongseo area of Gangwon-do, and the weather conditions of the Korean Peninsula were caused by the north-south-lower air pressure arrangement. If the seed is artificially sown when it is supersaturated and supersaturated, it is highly likely to succeed in the artificial expansion experiment. In particular, Gangwon-do is a representative mountainous region of South Korea, with the Taebaek Mountains extending inland and the sea between North and South, and the temperature is below freezing from November to March, making it suitable for artificial expansion or artificial experiments. In addition, the method of spraying ice tablets or clogged tuberculosis using live airflow on the upwind side of mountainous terrain is the most successful advantage known to the existing artificial expansion or artificial fire method.

And the cloud seed spraying step (S30) is sprayed to cross the direction of the wind blowing from the top of the target area to the top of the cloud or the cloud, if the wind speed is less than 3m / s 5km away from the artificial expansion or artificial rain target area It is preferable to spray cloud seeds on the wind side, and to spread the cloud seeds on the wind side 10 km away from the artificial expansion or artificial rain target area if the wind speed is less than 3 ~ 6m / s.

In other words, when the cloud flowed by the east wind flows upstream in the Taebaek Mountains, when the cloud reaches a supersaturated state, the clouding position is predicted using the direction and speed of the wind, and then the cloud seeds are sprayed in advance.

In addition, the number of cloud seed spreading spreads one silver iodide (AgI) per 10 km of one-way spreading path, so that the cloud seed spreading area is 100 mm wide x vertical, and the spreading area can be increased or decreased.

The step of verifying the artificial expansion or artificial rain effect using the aviation radar and the ground water concentration observation equipment from the seeding area to the target area (S40) includes an aviation radar (Radar: not shown) and an optical particle counter (Disdrometer: drawing) This step is to observe and verify the change of the target area snow (right) particles, especially before and after the experiment. At this time, the change of radar reflectivity before and after the experiment of snowfall (right) particle was observed and the snow particle concentration distribution observed by the optical particle counter, which is a ground water concentration monitoring device located at the seeding area and the target area at the same time. As a result, comparing the changes in radar reflectivity and water concentration from the seeding area to the target area before and after the experiment, it can be seen that the snow particle concentration was increased during the experiment.

Therefore, the artificial expansion or artificial rain target area seeding and verification method according to the present invention firstly maintains and prepares various mounted equipments with equipment for spraying cloud seeds on the aircraft.

Next, the aircraft is moved artificially (right) to the wind direction of the target area, and then artificially sprayed by crossing the wind direction coming from the wind direction of the target area by cloud or cloud.

At this time, the weather conditions according to the experiment is the cloud inflow by the east wind flows in the air pressure layout (North and South Korea) and cloud seed spraying area is below 40 ℃ ~ 5 ℃ below When this supersaturation is reached, the location of the wind is predicted using the direction and speed of the wind, and the cloud seeds are sprayed in advance according to the result.

Next, during the expansion process, using the aviation radar (not shown in the drawing) and the optical particle counter (Disdrometer: not shown in the drawing), the ground water concentration observation equipment, the seeding area and the target area snowfall (especially before and after the experiment) (B) Observe and verify particle changes.

After all, it is the artificial extension or artificial rain technology that can induce precipitation limited to the target area using the geographic features of the Taebaek Mountains and the direction and speed of the wind, and the flood caused by the precipitation of the unspecified area according to the artificial extension (right) experiment. By solving the problems of natural disasters and artificial natural disasters, and limiting artificial expansion or artificial rain technology to target areas, the advantages of artificial expansion (right) technology, such as securing water resources and eliminating drought, are emphasized. Even if the uncertainty does not depend on the large wind direction, it is to create and verify artificial expansion or hatch in the target area.

In the detailed description of the present invention described above with reference to the preferred embodiment of the present invention, the scope of protection of the present invention is not limited to the above embodiment, and those skilled in the art of the present invention It will be understood that various modifications and changes can be made in the present invention without departing from the spirit and scope of the invention.
