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).
A Ladder to the Sky is a 2018 novel by Irish novelist John Boyne, and his eleventh novel for adults. The plot concerns Maurice Swift, a handsome young writer who schemes, seduces, and plagiarizes his way to literary stardom. The novel received positive reviews from critics, and was shortlisted for Novel of the Year at the 2018 Irish Book Awards ...

A lightning-struck tree in the Toronto Islands, clearly shows the path that the charge took into the ground. Trees are frequent conductors of lightning to the ground. [27] Since sap is a relatively poor conductor, its electrical resistance causes it to be heated explosively into steam, which blows off the bark outside the lightning's path. In ...
Most of the sky-high footage was shot by the climbers themselves, using mounted cameras, drones, and selfie sticks, and the images have a dizzying wide-angle clarity that only heightens the ...
Sprites or red sprites are large-scale electric discharges that occur in the mesosphere, high above thunderstorm clouds, or cumulonimbus, giving rise to a varied range of visual shapes flickering in the night sky. They are usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground.
With reading proficiency and comprehension on the decline for years now in the U.S. (exacerbated by the pandemic), “Butterfly in the Sky” provides a much-needed pulpit from which to preach ...
