Time storm

A time storm, or a chronometeorological event (PROSE: Cat's Cradle: Time's Crucible), was 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)

Fenric took Ace through time in a time storm from her home town in Perivale, Earth to Iceworld, Svartos in order that she would meet the Seventh Doctor and then come to be of use in the final game against him. (TV: Dragonfire, The Curse of Fenric)

Fenric also took Lady Peinforte and her manservant Richard Maynarde from 1638 to 1988 in order to manipulate them into gathering the Nemesis statue. (TV: Silver Nemesis) Later, Fenric possessed a medalion in the form of a hammer that could conjour up time storms. (AUDIO: Gods and Monsters)
