Välkõrgete

Välkõrgete is an Estonian term that translates to "lightning strike" or "flash high" in English. It is often used to describe a sudden, intense burst of light, typically associated with thunderstorms. The phenomenon is caused by a massive electrical discharge within a cloud, between clouds, or between a cloud and the ground. This discharge heats the air to extremely high temperatures very rapidly, causing it to expand explosively and produce a bright flash. The sound that often follows a välkõrgete is known as thunder, which is the result of the rapid expansion and subsequent shockwave of the superheated air.

In a meteorological context, välkõrgete are a key indicator of severe weather. The frequency and intensity of lightning strikes can vary greatly depending on atmospheric conditions. While most are harmless, some can pose a significant risk to life and property, causing fires, damaging electrical systems, and even causing injury or death. The visual spectacle of a välkõrgete, particularly when illuminating the night sky, is often described as awe-inspiring, though it serves as a reminder of the powerful forces at play in nature. The study of lightning, including välkõrgete, is an important aspect of atmospheric science and meteorology.
