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 ...
Damaging wind gusts lashing up to 60 mph, hail the size of ping pong balls, brief tornadoes and frequent cloud-to-ground lightning are hazards the NWS said are possible in Beaufort County. The ...
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
The lightning flash rate averaged over the Earth for intra-cloud (IC) + cloud-to-cloud (CC) to cloud-to-ground (CG) is in the ratio: (IC+CC):CG = 3:1. The base of the negative region in a cloud is normally at roughly the elevation where freezing occurs. The closer this region is to the ground, the more likely cloud-to-ground strikes are.
A series of lightning strikes spidered across the New York City skyline the evening of Saturday, April 1, a few of which stretched from the World Trade Center into the clouds above in a dazzling ...
There are about 40,000 thunderstorms per day across the globe, generating roughly 100 lightning strikes per second, [1] which can be thought to charge the Earth like a battery. Thunderstorms generate an electrical potential difference between the Earth's surface and the ionosphere, mainly by means of lightning returning current to ground ...
