can there be lightning in a clear sky?

Answer 1

generally in the clear sky there is no lighting . lighting is caused by interaction of charged particles which are present in clouds therefore an electric field is created in the sky .if this electric field is strong enough to cause dielectric breakdown of moist air(air is moist in cloudy season).the dielectric constant of moist air is much more than dry air.therefore even if charge particles are present in sky the electric field created by them is not strong enough to cause dielectric breakdown of air.

Answer 2

No. Lightning is caused by the vertical transport of water droplets or ice pellets, so in a clear sky, where neither of these exist, there can be no lightning.

Answer 3

You can get struck by lightning under a clear blue sky, by a thunderstorm twenty miles away!

Answer 4

lightning occurs when the potential difference between the clouds and the earth is so great that they break the dielectric constant of air and electric dischargew occurs. now this excess of charges comes from the clouds. if there is something else that can create such a difference probable yes.

Answer 5

Yes it can. It is called heat lightning and the same thing goes for snow.

Answer 6

Lighting can happen any time there is a suffent difference in ground and air polarity. when it reaches a certain level then a discharge will occur usally in the form of heat lighting.

Answer 7

Yeah.Its called Hot Lightening.

Answer 8

yes, its called heat lightning.

Answer 9

yes lightning is about energy being released, not about rain.

Answer 10

Yes. If there is sufficient convective activity, even dry air will accumulate a charge.
