Lightning involves a near-instantaneous release of energy on a scale averaging between 200 megajoules and 7 gigajoules. [1][2][3] This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation.

2024年12月5日 · Lightning begins as static charges in a rain cloud. Winds inside the cloud are very turbulent. Water droplets in the bottom part of the cloud are caught in the updrafts and lifted to great heights where the much colder atmosphere freezes them.

2025年1月19日 · Lightning, the visible discharge of electricity that occurs when a region of a cloud acquires an excess electrical charge, either positive or negative, sufficient to break down the resistance of air. It can occur within the cloud, between clouds, between the cloud and the air, or between the cloud and the ground.

2023年4月5日 · The conditions needed to produce lightning have been known for some time. However, exactly how lightning forms has never been verified, so there is room for debate. Leading theories focus around separation of electric charge and generation of an electric field within a thunderstorm.

What is lightning? Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.

Lightning is an electrostatic discharge accompanied by the emission of visible light and other forms of electromagnetic radiation. How many volts and watts are in lightning? Lightning can have 100 million to 1 billion volts, and contains billions of watts.
