This is because when air flows around the tips of an aeroplane’s propellor and over its wings, it can cool in a localised area, causing the surrounding water droplets to drop to temperatures as low as -40 degrees and freeze.
A snowbow is a fairly rare phenomenon that forms when sunlight is reflected and refracted by ice crystals in the air (just as a normal rainbow is produced by the reflection and refraction of sunlight by raindrops).
Beside this, Can you see a rainbow when it snows?
People occasionally mistake some ice halos for rainbows, though. … Even so, we might see a rainbow or ice halo during a snowstorm. When temperatures are not too low, small raindrops occasionally accompany snow and could form a rainbow that shines through the snow.

Whats a sun dog mean?
Sun dogs are commonly caused by the refraction and scattering of light from plate-shaped hexagonal ice crystals either suspended in high and cold cirrus or cirrostratus clouds, or drifting in freezing moist air at low levels as diamond dust. … Larger plates wobble more, and thus produce taller sundogs.
What does a Sundog mean?
A sun dog (or sundog) or mock sun, also called a parhelion (plural parhelia) in meteorology, is an atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Sun. Two sun dogs often flank the Sun within a 22° halo.

What causes a Sundog Rainbow?
The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun.
What does a Sundog around the sun mean?
Sundogs and Weather Prediction Probably the biggest difference between the two is that a rainbow usually signals an end to the rain, while a sundog often means that rain, or snow is on the way.
