Halo usually appears around the Sun or moon, sometimes around other powerful light sources such as street lights. There are many types of halos, but they are mostly caused by ice crystals in Cirrus clouds at a height of 5-10 km in the upper troposphere. The form of the observed halo depends on the shape and arrangement of crystals. Reflected and refracted by the ice crystals, the light often turns into a spectrum, which makes halo look like a rainbow, but a halo in low light has a low chroma, which is associated with the peculiarities of twilight vision.

The storm is an atmospheric phenomenon in which the inside of clouds or between the cloud and the earth's surface arise electrical discharges - lightning accompanied by thunder. It is quite a common natural phenomenon in certain situations could be considered something abnormal, such as when it appears under unusual conditions or unfamiliar to the eyewitness. A vivid example is the so-called "snow storm" (or "snow storm"), i.e. thunderstorm, which is when rain falls heavy snow, freezing rain or ice pellets.

One of the most frequent types of halo, a visual phenomenon, an optical effect which is a vertical band of light stretching from the sun during sunset or sunrise.
