Cloud-to-ground (CG) lightning is either positive or negative, as defined by the direction of the conventional electric current between cloud and ground. Most CG lightning is negative, meaning that a negative charge is transferred (electrons flow) downwards to ground along the lightning channel (conventionally speaking they flow from the ground ...
Cloud-to-ground lightning. Typically, lightning discharges 30,000 amperes, at up to 100 million volts, and emits light, radio waves, x-rays and even gamma rays. [1] Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet).
Sympathetic lightning is the tendency of lightning to be loosely coordinated across long distances. Discharges can appear in clusters when viewed from space. [22] [23] [24] [clarification needed] Upward lightning or ground-to-cloud lightning is a lightning flash which originates from the top of a grounded object and propagates upward from this ...
A new study suggests that cloud-to-ground lightning likely provided the necessary material for the first organisms on Earth to form. All Life on Earth Might Have Started From Lightning, Scientists Say
A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning. A less common type of strike, ground-to-cloud (GC) lightning, is upward-propagating lightning ...
Lightning is detected remotely using sensors that detect cloud-to-ground lightning strokes with 95 percent accuracy in detection and within 250 metres (820 ft) of their point of origin.

Lightning-induced electron precipitation (also referred to as LEP) occurs when lightning strikes the Earth. When a bolt of lightning strikes the ground, an electromagnetic pulse (EMP) is released which can hit the trapped electrons in the radiation belt. The electrons are then dislodged and "precipitate" into the Earth's atmosphere. [1]
Scientists found quantum edge states in ultracold sodium atoms, possibly leading to highly efficient energy systems with minimal loss.
