Of Sprites, Lightning and Radiation

I found out today what a sprite is. It is the after effect of a lighning strike, but it is not on the earth, it actually goes upwards to the atmosphere and looks somewhat like the roots of a tree. Here is a picture -



Sprites formed by lightning

Now you know what a spite is. Everybody would know that whenever there is a nuclear reaction on the earth that is a big in magnitude it send of its radiation out in space about 4000 miles in altitude. This radiation causes the communication satellites not to function. It is something like a mini-solar-flare. There is a constant radiation layer over the earth but there is a saf area where the satillites function. But sometimes this safe area is filled with radiation and this radiation goes away after some time.


Satellite not functioning due to radiation

The rate at which this radioation is more where there is day, during summer and in the equatorial area. Anyone woul guess that the radiation goes away due to the sun's light or radiation. but that is wrong. Actually lightning also occurs moe in -

  • Day time
  • Summer
  • Equatorial Area

So actually, when there is lightning, it forms a sprite, and this sprite sends of radio waves to altitudes of 4000 miles and this clears of the radiation and the safe area is formed again

Cool aint it!!! Lightning is not only destructive, it also it very crucial or the normal working of satellites that control our communication, entertainment and the most importantly the INTERNET.
