Aurinkolasien

Aurinkolasi or aurinkolasien refers to a phenomenon where clouds or water droplets in the atmosphere are illuminated by the sun. This effect can create a range of colors and hues in the sky, from pastel shades to vibrant oranges and yellows.

Aurinkolasi occurs when the sun's rays pass through the upper atmosphere, where the air has become warmer and more humid. This causes the light to scatter off the water droplets or ice crystals, creating a spectrum of colors.

The colors observed in aurinkolasi are due to the selective scattering of sunlight by water droplets at different angles. At certain angles, the shorter wavelengths of light (such as blue and violet) are scattered more than the longer wavelengths (such as red and orange), creating the typically observed effect of the sky turning red or yellow during sunrise and sunset.

The term aurinkolasien translates from Finnish to "sunhalo" or "sunray", referring to the circular rainbow-like color seen around the sun when it is shining through water droplets in the air. The colors and intensity of aurinkolasi can vary depending on the amount of water vapor in the air, the size and distribution of the water droplets, and the position of the sun.

Overall, aurinkolasi is a visual phenomenon that can create a range of beautiful and striking colors in the sky. It is an interesting and lesser-known effect of the interaction between sunlight and atmospheric conditions.
