What is the use of manual lightning induction?

When it comes to artificial lightning, many people will think of Benjamin Franklin's famous "kite lightning experiment" more than 200 years ago. In the current era of rapid development of science and technology, the artificial lightning induced experiments conducted by researchers are no longer what they used to be.

As is well known, lightning occurs in strong convective weather systems with extremely strong instantaneity and randomness. Accurately predicting the time and location of lightning occurrence is very difficult, which poses a significant obstacle to quantitatively exploring the mechanism of lightning occurrence and development.

Contemporary artificial lightning induction is a technology that allows lightning to occur under known and controllable conditions.

According to Lv Weitao, deputy director of the State Key Laboratory for Disaster Weather of the Chinese Academy of Meteorological Sciences, the lightning strike position of artificial lightning is preset, which can be used for direct measurement of lightning channel current, short distance electromagnetic field measurement, and detection of high-energy radiation generated by lightning that is difficult to achieve in natural lightning, and can also use high-speed cameras to capture the refined development and transmission process of lightning channel. Artificial lightning induced tests can provide strong technical and data support for lightning monitoring, early warning and protection technology research in China.

In addition, many industries have a huge demand for lightning protection. Conducting artificial lightning induced tests can also use lightning to conduct protection technology and equipment testing, such as verifying the lightning protection capabilities of equipment and components in industries such as communication, power, energy, aviation, and the reliability of lightning protection devices.

Whenever strong convective weather occurs, the test personnel need to determine the timing of lightning induced operations in real-time under thunderstorm conditions. The best timing for lightning strike is when the electric field in the air is strong enough, quickly launching the lightning strike rocket into the air can greatly improve the success rate of lightning strike.

At present, the development and application of artificial lightning triggering technology in China have been at the forefront of the international community.

Since the first successful artificial lightning test was conducted using soil rocket towing wires in 1977, after nearly half a century of development, the success rate of China's artificial lightning test has reached 70% in recent years.
