👉 Atmospheric pimples, also known as atmospheric tufa clouds or noctilucent clouds, are high-altitude clouds that form in the mesosphere, typically at altitudes of around 76 to 85 kilometers. These clouds appear as bright, white patches against the dark backdrop of space and are often mistaken for pimples due to their distinctive, dot-like appearance. They form when water vapor freezes into ice crystals, creating a frothy, puffy texture that resembles small bumps or pimples. The exact mechanisms behind their formation are still under scientific investigation, but they are believed to be influenced by atmospheric conditions such as temperature inversions and the presence of meteoric dust. These clouds are most commonly observed during twilight hours in polar regions, particularly in summer months, and their rarity and ephemeral nature make them a fascinating subject of meteorological study.
