Crepuscular rays are atmospheric optical phenomena that occur when sunlight is scattered by particles in the atmosphere, creating visible beams of light that appear to radiate from the sun. These rays can be observed during sunrise or sunset, and they often form a beautiful pattern resembling a fan or cone of light spreading outwards from the sun. The combination of "☀️🌦️🌈" represents the interplay of sunlight, passing through clouds (🌦️), and creating a stunning rainbow (🌈) effect alongside crepuscular rays (☀️).
