Lichtenberg figures are fern-like patterns that may appear on the skin of lightning strike victims and typically disappear in 24 hours. [10] They are also known as Keraunographic markings. [11] A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck.

Dec 18, 2017 · Lightning can strike the ground, the air, or inside clouds, but there are roughly 5 to 10 times more cloud flashes than cloud-to-ground flashes. In CG lightning, a channel of negative charge, called a stepped leader, will zigzag downward in a ‘forked’ pattern - hence it is sometimes called forked lightning.

Lightning Types. Most lightning starts inside a thunderstorm and travels through the cloud. It can then stay within the cloud or continue to travel through the open air and eventually to ground.

Jun 4, 2024 · "Lichtenberg figures" are branching, tree-like patterns that are created by the passage of high voltage electrical discharges along the surface, or inside, electrically insulating materials (dielectrics).

Jan 23, 2025 · NASA’s lightning data, collected from the ground, air, and space, help scientists understand lightning patterns and predict severe weather. Lightning is the electrical discharge between positively and negatively charged regions within clouds. Visually, lightning is comprised of bright flashes of light called strokes.

We now have a better understanding of why lightning occurs and where, what lightning patterns exist over the globe, and what lightning tells us about atmospheric convection. Lightning continues to be studied by scientists and engineers who use a variety of instruments.

These dramatic "keraunographic" marks are sometimes referred to as "lightning flowers" or "lightning trees." They tend to occur on the arms, back, neck, chest, or

Jan 14, 2023 · The characteristic zigzag pattern of lightning is caused by a highly conductive form of oxygen that builds up as the bolt travels toward the ground.

Mar 10, 2012 · Lichtenberg figures are branching electric discharges that sometimes appear on the surface or the interior of insulating materials. They are named after the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them.

Both terrifying and thrilling, lightning is one of the most obvious signs of the immense energy involved in severe storms. Detecting lightning strikes is important for improving public safety during severe weather, warning land managers of possible wildfire triggers, and protecting electrical and transportation systems.
