Abstract

This study applies a novel cloud seeding method using an unmanned aerial vehicle (UAV) and a research aircraft in Korea. For this experiment, the UAV sprayed a cloud seeding material (calcium chloride), and the aircraft monitored the clouds in the southern part of the Korean Peninsula on April 25, 2019. Cloud observation equipment in the aircraft indicated an increase in the number concentration and average particle size of large cloud particles after the seeding. Weather radar reflectivity increased by approximately 10 dBZ above the experimental area due to the development of clouds and precipitation systems. Rain was observed after seeding, and 0.5 mm was recorded, including natural and mixed precipitation from the cloud seeding. In addition, it showed that the rapid increase in the number of raindrops and vertical reflectivity was approximately 10 dBZ. Therefore, these results showed the possibility of cloud seeding using UAVs and atmospheric research aircraft. The effects of cloud seeding are indicated through the increased number concentration and size of cloud particles, radar reflectivity, and ground-based precipitation detection.

韩国无人机和大气研究飞机播云实验技术的进展与展望

这项研究应用了一种新的云播种方法，使用无人机和韩国的研究飞机。在这次实验中，无人机喷洒了一种播云材料（氯化钙），飞机于2019年4月25日监测了朝鲜半岛南部的云层。飞机上的云观测设备显示，播种后，大型云粒子的数量浓度和平均粒径有所增加。天气雷达反射率增加了约10 由于云层和降水系统的发展，实验区上空的dBZ。播种后出现降雨，0.5 毫米，包括来自云层播种的自然降水和混合降水。此外，研究表明，雨滴数量和垂直反射率的快速增加约为10 dBZ。因此，这些结果显示了使用无人机和大气研究飞机进行云层播种的可能性。通过增加云粒子的数量、浓度和大小、雷达反射率和地面降水探测来表明播云的影响。
