Red sprites and blue jets are both atmospheric and electrical phenomena that take place in the upper atmosphere. They take place above normal lightning; Blue jets happen in cone shapes above thunderstorm clouds, and are not related to lightning. They’re blue due to ionised emissions from nitrogen. Red sprites can appear as different shapes and have hanging tendrils. They occur when positive lightning goes from the cloud to the ground.
“Mammatus clouds are most often associated with the anvil cloud and severe thunderstorms. They often extend from the base of a cumulonimbus, but may also be found under altocumulus, altostratus, stratocumulus, and cirrus clouds, as well as volcanic ash clouds. When occurring in cumulonimbus, mammatus are often indicative of a particularly strong storm or perhaps even a tornadic storm.”
My dad taught me about these when I was a child. From previous pinner: Not every cloud has a silver lining; this multi-coloured cloud looks as if a rainbow has formed high in the heavens. The phenomenom - called a sundog - happens when ice crystals appear in clouds and refract the sun's rays. Photographer Robert Arn captured the cloud in Heyworth, Illinois, America.

An incredible roll cloud dominates the skies above the photographer's house in Australia. Roll clouds ocurr ahead of storm fronts The roll cloud is a subtype of arcus cloud - the funnel is horizontal and does not connect to the ground.The other subtype of arcus is a shelf cloud, which also often appear to precede storm fronts.
This bizarre electrical phenomenon usually occurs during thunderstorms and lasts for up to thirty seconds. Balls of lightening are said to behave in strange ways, hovering, rolling, hissing and sometimes passing through walls, in a way that seems completely unnatural. As a result, ball lightening has long been associated with aliens and ghosts, and the kind of pseudo-psychic head-cases who believe they can communicate with the other side.
Near Alice Springs, Australia, 30 metre high tornado of FIRE that whirled around Australian outback for terrifying 40 minutes Fire tornadoes occur when a column of warm, rising air contacts with or creates fire on the ground. An astonished filmmaker is coming to grips with the moment he witnessed one of nature's rarest phenomenons - a tornado comprised entirely of fire- and lived to tell the tale. Chris Tangey had been out in Alice Springs, Australia, scouting locations for a new movie.
