Time storm
A time storm, or a chronometeorological event (PROSE: Cat's Cradle: Time's Crucible), was a temporal anomaly as well as a method of time/space transportation that could be viewed and experienced in many forms. Typically it was directly experienced by the people being taken through time as a swirl of coloured light, and unlike traversing the vortex in a TARDIS it was a tangible experience. (TV: Silver Nemesis)
