A light pillar or ice pillar is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. The effect is created by the reflection of light from tiny ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (e.g. cirrostratus or cirrus clouds ). [ 1 ]

2023年10月19日 · Light pillars are optical phenomena that occur in extremely cold atmospheres, when flat ice crystals form close to the ground. They reflect natural and artificial light in columns that extend through the sky. When the night grows frighteningly dark and the temperature hovers near freezing, you probably can’t even imagine coming out of your house.

2023年3月15日 · Sun pillars and light pillars are beams of light that extend vertically upward (or downward) from a bright light source, such as the sun or another bright light low on the horizon. They can...

2022年2月4日 · Light pillars are optical atmospheric phenomena where pillars of light appear to beam up from the ground into the sky. The ideal weather conditions for this to occur are on a frigid winter...

Light pillars occur when natural or artificial light reflects off flat ice crystals in the air close to the Earth’s surface. Light pillars caused by the Sun are called Solar or Sun pillars, while those caused by the Moon’s light are called Lunar or Moon pillars.

2018年5月10日 · A light pillar is one such optical phenomenon which results from the interaction of ice crystals in the atmosphere with light, which could either be natural or artificial. The mode of creation of the pillars is reflection of the light by the ice crystals.

2017年1月27日 · Light pillars can be a spectacular sight in the colder months of the year, despite being a largely man-made phenomenon. They're most commonly seen when nearly flat, hexagonal-shaped ice crystals...

2024年12月27日 · What look like light sabers or giant spotlights shooting straight up in the sky, light pillars are one of the most magnificent optical illusions. Light pillars occur when plate-shaped ice...

2024年1月11日 · Recently, residents of large cities have observed bright light pillars rising above all bright light sources. Let’s try to figure out what this optical effect is related to and what it indicates. The Earth’s air always contains a certain amount of water vapor.

Light pillars are an optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source. Light pillars typically occur in arctic regions due to the temperatures required for such an event. When the atmosphere becomes extremely cold, flat ice crystals form in the air close to the ground.
