Helpful Information: "There was lightning and I heard thunder, but nothing was recorded - why?" There are three mains types of lightning. Palmy Weather only records "Cloud-to-Ground" (CG) and "Ground-to-Cloud" (GC) lightning. However the most common types of lightning is "Intracloud" (IC) and Cloud-to-Cloud (CC) lightning. Find out more about the types of lightning here.

More accurate data including triangulation for exact lightning strike location could be obtained through multiple sensors spread widely across the city but is not practical and is cost prohibitive.

About Types of Lightning - In order of prevalence

Intracloud (IC):
The most common type of lightning. It happens completely inside the cloud, jumping between different charge regions in the cloud. Intracloud lightning is sometimes called sheet lightning because it lights up the sky with a 'sheet' of light.

Cloud-to-Cloud (CC):
Lightning that occurs between two or more separate clouds.

Cloud-to-Ground and Ground-to-Cloud (CG / GC) [what Palmy Weather is detecting]:
Lightning that connects a cloud to the ground. This can be a negative flash (cloud to ground) or a positive flash (ground to cloud). Cloud-to-ground (CG) and ground-to-cloud (GC) lightning is the most likely type to cause damage to life and property because it makes direct contact with the Earth's surface, although less common than in-cloud lightning.

Cloud-to-Air (CA):
Lightning that occurs when the air around a positively charged cloud top reaches out to the negatively charged air around it.

Bolt From the Blue:
A type of positive lightning bolt that originates in the upper part of a storm, travels horizontally for many kilometres and then strikes the ground at a significant distance from the storm's base. You may not even be aware there is a thunderstorm nearby.

Anvil Lightning:
A positive lightning bolt that develops in the anvil, or the top, of a thunderstorm and travels down to the ground.

Heat Lightning:
A general term for the visible flashes of a distant thunderstorm where the thunder is not heard due to the distance.

Sprites, Wlves, and Blue Jets:
Rare, high-altitude electrical discharges that occur above the clouds in the upper atmosphere and have been studied more recently.
