Abstract
Description
Изобретение относится к метеорологии и может быть использовано для вызывания осадков из конвективных облаков. The invention relates to meteorology and can be used to cause precipitation from convective clouds.
Цель изобретения - расширение диапазона регулирования осадков путем обеспечения возможности их уменьшения или увеличения. The purpose of the invention is the expansion of the range of regulation of precipitation by providing the possibility of their reduction or increase.
Искусственная интенсификация роста облаков и соответствующее последующее увеличение осадков происходят при определенных значениях мощности переохлажденной части облаков, имеющей нижний и верхний пределы. Предельно малая мощность переохлажденной части облака составляет 1,5 км. Предельно большая мощность переохлажденной части облака достигает 5 км. С дальнейшим ростом мощности переохлажденного слоя количество дополнительных осадков относительно интенсивности естественных осадков убывает. Artificial intensification of cloud growth and the corresponding subsequent increase in precipitation occur at certain thicknesses of the supercooled part of the clouds, which has lower and upper limits. The extremely low power of the supercooled part of the cloud is 1.5 km. The extremely large thickness of the supercooled part of the cloud reaches 5 km. With a further increase in the thickness of the supercooled layer, the amount of additional precipitation decreases with respect to the intensity of natural precipitation.
Интенсификация развития облаков по мощности достигается искусственной кристаллизацией практически всей переохлажденной воды в облаке и выделением тепла кристаллизации во всем объеме переохлажденной части облака, содержащей жидкокапельную влагу. За счет этого увеличивается плавучесть облака, и оно растет. Переохлажденная вода, подлежащая кристаллизации, расположена в облаках между изотермами -8оС (порог действия кристаллизующих реагентов) и -25оС (выше этой изотермы жидкая вода содержится в небольших количествах).The intensification of cloud development by power is achieved by artificial crystallization of almost all supercooled water in the cloud and the release of heat of crystallization in the entire volume of the supercooled part of the cloud containing liquid droplet moisture. Due to this, the buoyancy of the cloud increases, and it grows. Freezing the water to be crystallized in clouds is between -8 ° C isotherms (action threshold crystallizing reagents) and -25 C (above this isotherm liquid water is contained in small amounts).
Уменьшение осадков из конвективных облаков при засеве конвективных облаков с мощностью переохлажденного слоя до 1,5 и свыше 5 км связано с преждевременным разрушением таких облаков в результате интенсивного вымывания облачной массы. The decrease in precipitation from convective clouds during the sowing of convective clouds with a supercooled layer thickness of up to 1.5 and more than 5 km is associated with the premature destruction of such clouds as a result of intensive leaching of the cloud mass.
Таким образом, осуществляя засев жидкокапельной части облака с концентрацией льдообразующего аэрозоля более 104 м3, можно достичь регулирования осадков: их уменьшение, осуществляя засев облаков с мощностью переохлажденной части менее 1,5 и более 5 км, и их увеличение при мощности переохлажденной части в диапазоне 1,5-5,0 км.Thus, by sowing the liquid droplet part of the cloud with an ice-forming aerosol concentration of more than 10 4 m 3 , it is possible to achieve precipitation control: reduce them by sowing clouds with a supercooled part with a thickness of less than 1.5 and more than 5 km, and increase them with a supercooled part in the range of 1.5-5.0 km.
Предлагаемый способ регулирования осадков из конвективных облаков осуществляют следующим образом. The proposed method for regulating precipitation from convective clouds is as follows.
Используя самолетные или радиолокационные средства измерений облаков, производят отбор облаков, а именно: если необходимо увеличить осадки, отбираются облака с мощностью переохлажденного слоя 1,5-5,0 км; если необходимо уменьшить осадки, отбираются облака с мощностью до 1,5 и свыше 5,0 км. Using airplane or radar cloud measurement tools, clouds are selected, namely: if it is necessary to increase precipitation, clouds with a supercooled layer thickness of 1.5-5.0 km are selected; if it is necessary to reduce precipitation, clouds with a thickness of up to 1.5 and more than 5.0 km are selected.
В обоих случаях производится засев облаков путем отстрела с самолета пиропатронов ПВ-50 и ПВ-50М. Способ был испытан на метеорологических полигонах. In both cases, cloud sowing is carried out by shooting pyrocartridges PV-50 and PV-50M from an airplane. The method was tested at meteorological sites.
Результаты испытаний приведены в таблице. The test results are shown in the table.
Таким образом, выбор соответствующих условий воздействия позволяет расширить диапазон регулирования осадков. Thus, the selection of appropriate exposure conditions allows you to expand the range of regulation of precipitation.
