ice crystals

The ice crystals tag on WindowsForum.com covers atmospheric optical phenomena involving ice crystals in the air. Discussions include sightings of phantom suns or sundogs, where ice crystals in clouds refract sunlight to create bright spots or halos around the sun. A thread titled 'Triple Sun seen over China' explains that such phenomena occur in winter when clouds are composed of ice crystals, leading to optical refractions. Another thread, 'Wild Dance,' features an image of crystalline ice formations. These posts explore the visual effects of ice crystals in nature, from atmospheric optics to artistic depictions.
