It is a common phenomenon, though the atmospheric conditions needed to opacify the vortex are less common.
Some vortices are deliberate. The chine or strake shown here generates a visible vortex that delays airflow separation at low speed and high angle of attack ... rather useful when taking off and landing. The absence of "source scuzz" shows that a different mechanism is working here.
Twisted love!
