I believe @haruspex nailed it. A charge induce on the ground by a cloud is called induction. It's the term used in that situation.

Also known as induction.

I would interpret the diagram this way: Both clouds are discharging electrons (negative charge) to the ground. This is evidence that...

Ssongoku replied to the thread Which one is correct statement regarding lightning?.If that is the case, there is discharging between the clouds so can I say there is induction between clouds? Thanks

(i) Your work is correct, but your notation should be clearer. should be $$ \hat{\theta}=\frac1n\sum_{i=1}^{n}X_i^2 $$. (ii) I do not...

SWell, it doesn’t say the moth is flying directly towards the bat. Perhaps it was supposed to tell you it was flying at an angle of 60°...
