| You can get an explanation of the optics behind fogbows as well as a collection of other stunning images on this Atmospheric Optics webpage. |
|
| Fog and clouds contain such small droplets, and thus the bows arising from them are known as fogbows or cloudbows rather than rainbows. |
|
| Lunar rainbows, cloudbows and fogbows are similar to rainbows but are generally much fainter. |
|
| As rainbows and fogbows form under very similar conditions, I thought that it also should be possible to observe rainbows in diverging light. |
|
| Very cold air can't hold as much moisture as warmer air, and therefore fogbows often appear in cold areas. |
|
| There are very good images of rainbows but also lots of other interesting ones like sundogs and fogbows. |
|
| Unlike rainbows, fogbows are rare because the light source has to be low at the back of the observer and the fog mostly in the opposite direction. |
