What does lightning mean on upward?
The most important finding about upward lightning, is that it primarily occurs when there is a nearby positive cloud-to-ground flash. The electric field change caused by the preceding flash causes an upward positive leader to initiate from a tall object such as a building, tower or wind turbine.

- Do not lie on concrete floors, and do not lean against concrete walls.
What triggers upward lightning?
Upward triggered lightning usually occurs in response to a natural lightning flash, but on rare occasions can be “self-triggered”—usually in winter storms with strong winds. Lightning can also be triggered by aircraft flying through strong electric fields. If the plane is below the cloud, then a CG flash could result.
How common is upward lightning?
While an upward lightning strike is uncommon, it obviously does happen. Lightning forms due to positive and negative charges in the atmosphere. Typically, the cloud top has positive charges with negative at the bottom. Once we get enough charges in the atmosphere, lightning strikes.

Can lightning go from ground up?
Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
Is it safe to use phone while lightning?
It advises people to use mobile phones instead of conventional corded telephones during storms because conventional phones pose a well documented risk. The real risk presented by this letter is people may not have their mobile phone with them to call emergency services if someone is struck by lightning nearby.
