Lightning results from the buildup and discharge of electrical energy between positively and negatively charged areas.
Rising and descending air within a thunderstorm separates these positive and negative charges.
Lightning is usually produced by cumulonimbus clouds, which have bases that
are typically 1–2 km (0.6-1.25 miles) above the ground and tops up to 15 km (9.3
