Abstract

The author propose a new method for cloud modification that does not involve rockets and aircrafts. It is based on some works in the field of protecting agricultural crops from hail using the rocket technology, as well as the achievements in the cloud modification using ground-based generators in Brazil. The new method is founded on the experimental data and theoretical calculations of the behavior of ice-nucleating particles in case of their generation near the ground and at the height close to the level of free convection during air-mass and frontal precipitation-forming processes. It is proposed to introduce ice-nucleating particles to the level of convective flux formation so that then the particles enter the area of origin and growth of hail in a cloud cell on their own. In the rocket technology, the identification of this area is one of the major difficulties of radiolocation. The proposed technique provides the ice-nucleating particle delivery to the hail area without any use of radiolocation. The method also allows avoiding safety problems arising from launching rockets over densely populated areas.

通过在上升气流形成水平上播种冰核来调节对流云降水

摘要

作者提出了一种不涉及火箭和飞机的云修改新方法。它基于利用火箭技术保护农作物免受冰雹影响的一些工作，以及巴西利用地面发电机进行云改造的成就。新方法建立在冰核颗粒在气团和锋面降水形成过程中在地面附近和接近自由对流水平的高度生成时的行为的实验数据和理论计算的基础上。建议将冰核粒子引入对流通量形成水平，以便粒子自行进入云单元中冰雹的起源和生长区域。在火箭技术中，该区域的识别是无线电定位的一大难点。所提出的技术无需使用任何无线电定位即可将冰核粒子输送到冰雹区域。该方法还可以避免在人口稠密地区发射火箭所引起的安全问题。
