JD is right. From the pilot/controller glossary:
WAKE TURBULENCE- Phenomena resulting from the passage of an aircraft through the atmosphere. The term includes vortices, thrust stream turbulence, jet blast, jet wash, propeller wash, and rotor wash both on the ground and in the air.
In the 1980s at LAXT I remember having to change my ground control phraseology from 'jet blast' to 'wake turbulence'. I also remember seeing a Cessna relocated a few hundred feet when taxiing accross a rwy that a DC10 just started takeoff roll on.
