A device and method for regional combined catalysis of precipitation

Abstract

The present invention provides a kind of device and method of regional joint catalytic rain and snowfall, and this device comprises measurement and control system, high-voltage generator, high-voltage cable, emitter electrode, high-voltage tower frame, insulating structure, and the quantity of high-voltage tower frame is N ( N≥2), the high-voltage generator is connected to the emitter electrode through a high-voltage cable. There are N emitter electrodes (N≥1). The emitter electrode generates corona discharge, generates a large amount of plasma around it, and emits a large amount of charges and negative ions. Negative ions are transported to high-altitude clouds under the action of updraft and free diffusion, and then affect the microphysical processes in the cloud, resulting in rainfall or snowfall. The invention reduces the influence of cloud system operation conditions on artificial weather modification, widens the operation conditions and requirements, increases rainfall or snowfall, and can realize the purpose of regional rain and snowfall.

Description

technical field [0001] The invention belongs to a novel method and device for manipulating the weather, in particular to a device and method for electrocatalyzing rain or snowfall. Background technique [0002] At present, the traditional methods of artificial weather modification basically use material catalysis to enhance the formation and growth of cloud droplets. Catalysts are generally released into the clouds by aircraft and rockets, or reach the clouds through updrafts through incinerators on the surface. [0003] The principle of traditional weather modification is mainly divided into two types: one is to introduce catalysts (dry ice, silver iodide) into the cloud during the process of artificial weather modification, which will generate a large number of ice crystals in the target area, which will increase the cooling rate to a certain extent. The efficiency of cloud precipitation, this process is called static catalysis; another principle is to change the dynamic s...

AI Technical Summary

Problems solved by technology

[0004] However, the traditional way of artificially modifying the weather has its unavoidable defects: First, the conditions of traditional artificial rainfall enhancement are harsh. The operation can only be effective under the condition of rainfall. The traditional artificial rainfall enhancement method must have a cloud system with suitable operating conditions, and the temperature window is narrow. Rain enhancement works are effective

Secondly, traditional artificial rainfall enhancement operations are strictly controlled. If aerial vehicles are used to sow, aviation control must be applied for before the operation. In addition, the production, storage, transportation, and use of rockets, anti-aircraft artillery launchers and their ammunition are strictly controlled.

Finally, vehicles (aircraft, rockets, anti-aircraft guns, etc.) have high operational requirements, and are expensive to maintain and use (man-made influence operation costs reached 1.8 billion in 2010), and some chemical substances contained in catalysts have adverse effects on the environment
