A Time Wake was an anomaly in the Time Vortex caused by the use of (primitive) time travel technology, (PROSE: Time Wake [+]Doctor Who Annual 1986 (Doctor Who annual, 1985).) although DARDISes and TARDISes also left them. (AUDIO: The Elite [+]Error: Code 2 - no data stored in variables, cache or SMW.)
They were "rather like the wake left behind by a ship at sea." They presented themselves as shimmering blue-white rings that people could step directly through and be transported to wherever the Wake took them. They "healed themselves" after primitive time travel excursions were halted, the circumference of the ring closing in a gradual constriction, proving lethal if one attempted to enter at a point where the circumference could not accommodate their personal size.
The Sixth Doctor told Peri Brown encountered a Time Wake created by Tasq, a Time Engineer from the planet Bestonas, that connected London in January 1986 to London in 1720. (PROSE: Time Wake [+]Doctor Who Annual 1986 (Doctor Who annual, 1985).)
TARDISes left temporal wakes as areas in the vortex where it had recently been or would be, meaning a TARDIS could cross its own wake. (PROSE: Imperial Moon [+]Christopher Bulis, BBC Past Doctor Adventures (BBC Books, 2000).) Ramón Salamander believed he had drifted through the Time Vortex in the wake of the Doctor's TARDIS, arriving on Earth only minutes after him in the 1960s "or perhaps another decade."

Because she merged with part of his TARDIS, the Seventh Doctor was able to track the wake of the Timewyrm and follow her. (PROSE: Timewyrm: Genesys [+]John Peel, Virgin New Adventures (Virgin Books, 1991).) The Headhunter programmed Morbius' stellar manipulator to follow the Eighth Doctor's TARDIS's time wake as she locked it onto Lucie Miller's DNA. (AUDIO: Worldwide Web [+]Eddie Robson, Eighth Doctor Adventures (Big Finish Productions, 2009).)
The ruptured core of a Dalek time machine left a temporal wake that dragged the Fifth Doctor's TARDIS off course. (AUDIO: The Elite [+]Error: Code 2 - no data stored in variables, cache or SMW.)
