Secondly, what causes lightning? Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.
Beside above, what is a lightning warning?
A lightning prediction system is a type of lightning detection equipment that determines when atmospheric conditions likely to produce lightning strikes and sounds an alarm, warning those nearby that lightning is imminent and giving them the chance to find safety before the storm arrives in the area.
Why is there so much lightning in Singapore?
The country is situated near the equator and has warm and humid tropical conditions highly favourable for the development of thunderstorms.
