Lightning
Because there is a potential difference between two objects.

An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionisation of the gas. Depending on several factors, the discharge may radiate visible light.
Static Discharge:Perhaps you see a spark jump between your hand and the doorknob. The spark is an example of an electric discharge. An electric discharge is the movement of static charge from one place to another. The spark you saw was the result of a static charge moving between your hand and the doorknob.
Ionic bond is characterised by formation of oppositely charged particles
You have a spark jumping the gap between the surfaces.......
Lightning is a common answer, but the clouds are not really a surface. A spark would be a more general description for this phenomenon, such as in a spark plug in your car's engine.
Lightning is a massive electrostatic discharge caused by unbalanced electric charge in the atmosphere, either inside clouds, cloud to cloud or cloud to ground, accompanied by the loud sound of thunder.
A spark
It is not a rising of air mass, It is caused by an unbalance in the atmosphere; which an eletric discharge is taking place.Lightning is an electric discharge between a positively charged area and a negatively charged area.a rising air mass

An electrical spark.
When metals react, they lose electrons to become stable and sometimes form a compound
Ionic (electric) attraction forces of (sodium) Na+ and (chlorine) Cl- ions. (i.e. of oppositely charged particles)
When polar molecules are placed between oppositely charged metal plates they will align themselves. They align in the direction of the field.
Benjamin Franklin. The very famous scientist who did experiments with flying kites during lightning and declared that lightning is due to the electrical discharge between oppositely charged clouds.
