Time storm

A time storm or timestorm, also known as a chronometeorological event, (PROSE: Cat's Cradle: Time's Crucible) was a method of time/space transportation that could be experienced in many forms. Unlike traversing the time vortex in a TARDIS, time storms were usually directly experienced by the people being transported as a swirl of light and colours, (TV: Silver Nemesis) including scarlet, aqua, gold, white, heliotrope, lime, and vermilion, as it snapped out waves of random energy. (PROSE: Set Piece)

Natural phenomenon
Time storms could be emitted by time rifts. (PROSE: Set Piece) The Third Doctor claimed to have seen time storms off Gallifrey (PROSE: The Loneliness of the Long-Distance Time Traveller) and the Tantalus Eye emitted temporal storms along with time winds. (PROSE: Engines of War) Ergostorms were a form of time storm that could occur in the ergosphere of a black hole in the hole was collapsing, causing space and time to warp. (AUDIO: Aquitaine)

In 2010 Elizabeth Meadows said that a temporal storm damaged a Cyberman ship and caused it to crash to the Arctic Circle ten thousand years prior. (GAME: Blood of the Cybermen)
