Halo (optical phenomenon)

From Wikipedia, the free encyclopedia

A halo (ἅλως; also known as a nimbus, icebow or Gloriole) is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. Many are near the sun or moon but others are elsewhere and even in the opposite part of the sky. They can also form around artificial lights in very cold weather when ice crystals called diamond dust are floating in the nearby air.

There are many types of ice halos. They are produced by the ice crystals in cirrus clouds high (5–10 km, or 3–6 miles) in the upper troposphere. The particular shape and orientation of the crystals is responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting sunlight between their faces, sending shafts of light in particular directions.

Atmospheric phenomena such as halos were used as part of weather lore as an empirical means of weather forecasting before meteorology was developed.

Other common optical phenomena involving water droplets rather than ice crystals include the glory and the rainbow.

My goal is to get my name out there among the vast ocean of Natural photographers. To be known for my skill with a Point & Shoot~

My images are not photo shopped. They have only been adjusted with basic sharpening, contrasting & saturation techniques. I believe that in order to appreciate Nature, you have to capture it as it is, naturally.

    Neat find Kimberly…enjoyed your read as well…Up in Canada, when our winter days are extremely cold (-40c) we often get a sundog or parthelion, often referred to as an “optical phenomonen” when a bright spot in the sky on either side of the sun is formed by refractions of sunlight through ice crystals high in the atmosphere during extreme cold weather…..Love the silhouetted cactus…Very effective work …inst fave BTW!!!

  • Thank you my dear friend! You can keep your cold days, I prefer my heat…lol!
