If the local air mass is rising, it will slow the sink or even raise the
vortex.

Real people in real airplanes training to become real pilots do real
45 degree bank, constant altitude turns on a regular basis and run into
their real wake.

My research indicates that this is not possible. The wake sinks at a rate
between 150 and 500 feet per minute (roughly). Thus, it would always be
well
below the airplane by the time it closes its own circle, unless the
airplane
is also descending.

I've seen reports of pilots descending in a 360-degree turn and running
into
their own wakes. If they can descend and encounter their own wake, then
they
cannot remain at the same altitude and encounter it. It cannot be in two
places at once.
