3. Ball Lightning
Ball lightning is an unexplained atmospheric electrical phenomenon that refers to a luminous, usually spherical object (and it’s not a piece o’ the car) which can vary from pea-sized to several meters in diameter. It is usually associated with thunderstorms, but lasts considerably longer than the split-second flash of a lightning bolt.
Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon. Scientific data on natural ball lightning are scarce owing to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and has therefore produced somewhat inconsistent findings. Because there is a real lack of data on the phenomenon, the true nature of ball lightning is still unknown.
4. Fire Rainbow
Also called a circumhorizontal arc, a fire rainbow is an optical phenomenon formed by ice crystals in high altitude cirrus clouds. If you are very lucky and live at the right latititude, you might see one, possibly two in your entire lifetime. Cirrus clouds are those spread-out, wispy looking clouds that you see way up past the regular, fluffy ones. They are so wispy because there is very little moisture in the air at that altitude.
Despite the fact that cirrus clouds are common, fire rainbows are not. This is for the same reason that you only see a regular rainbow under certain circumstances. The light from the sun has to hit these particular ice crystals at exactly the right angle or the light will not separate (refract) into its colorful components – at least 58 degrees above the horizon. Because of the absolutely specific height of the sun you will not see a fire rainbow south or north of 55 degrees. amazing things, amazing things,amazing things
