Fénysávok

Fénysávok, often translated as light streaks or light beams, is a term used to describe visible columns or shafts of light that appear to emanate from a single point in the sky. These phenomena are typically observed when sunlight is scattered by atmospheric particles such as dust, water droplets, or ice crystals. The effect is most commonly seen when the sun is low on the horizon, either at sunrise or sunset, and is partially obscured by clouds, mountains, or other obstructions.

The appearance of fénysávok is a result of atmospheric optics. The light rays from the sun are essentially parallel, but the perspective of the observer, combined with the scattering of light by aerosols, makes them appear to converge at a point. This point is often antipodal to the sun, meaning it is on the opposite side of the sky from the sun itself. When seen in this way, the phenomenon is also known as crepuscular rays.

These light beams can sometimes extend all the way to the horizon, creating a dramatic visual display. They are often associated with the passage of weather fronts, as clouds can play a crucial role in creating the necessary conditions for their formation. While beautiful and often photographed, fénysávok are a natural atmospheric phenomenon with no specific scientific or meteorological significance beyond indicating the presence of certain atmospheric conditions. They are a common sight in many parts of the world and are a popular subject for landscape photography.
