not quite, wake turbulence refers to the turbulent air left behind an aircraft and includes the turbulent air due to the wing tip vortices.......do a search on here for that if you want to know more about what causes them in detail, but basically the way the wing produces lift is by the aerofoil shape causing lower pressure above the wing and higher pressure below the wing which 'sucks' the wing upward, as a consequence of these differing pressures the higher pressure air naturally tries to mix into the lower pressure and thus 'escapes' from under the wing-tip around to above the wing. As the wing is moving forward at speed the resultant 'mixing' forms a tight spiral motion of air trailing from each wingtip (these can often be seen in moist air). These spirals are like mini-tornados and do not dissipate immediately, hence the need for a time gap between aircraft landing/taking off on the same runway (where they will pass pretty much through the same air) as this wake turbulence can be very dangerous for a following aircraft, especially if it is lighter than the preceding a/c.
