Term : Lightning
|
Definition : Electrical discharge between a highly-charged cloud and another cloud or the planetĀ?s surface. On earth, energy from the sun is the ultimate source for creating lightning. Warmth from the sun's radiant energy is responsible for convection of air, and frictional effects cause the separation of charges which makes lightning possible. The lightning flash is composed of several strokes. The first, called the stepped leader, originates from the cloud. It comprises brief (~ 1 ms) spikes in electrical current (to more than 1000 A) separated by times of lesser current ( 50 ms, ~100 A). This part of the lightning flash sets the jagged shape that the later, more intense return strokes (currents originating from the earth) will follow. The return strokes may have currents in excess of 30 kA, each lasting for about 50 ms. A typical
lightning flash transfers a net negative charge of about 10 C from the atmosphere to the earth. See also http://FusEdWeb.pppl.gov/CPEP/Chart_Pages/5.Plasmas/Lightning.html

| Planet Dictionary |
 |
A planet (from the Greek planete means "wanderer" or
more forcefully "vagrant, tramp") is an object in orbit around a star
that is not a star in its own right. Much like "continent," "planet"
is a word without a precise definition, with history and culture playing
as much of a role as geology and astrophysics
