Busting out of the clouds? Can you swirl a bit of a vortex in the clouds?

So, would it be caused by the wings or the prop? The images I find show two vortices swirling inward behind the plane but they are all twin engine jets.Busting out of the clouds? Can you swirl a bit of a vortex in the clouds?

That shot is a Paul Bowen specialty and the vortices are from the wing tips in cruise flight with flaps up. There are normally no vortices from engine nacelles. At high altitude and cold temperatures contrails will form but not until the exhaust has cooled sufficiently for the water vapor to condense, some distance behind the airplane. Vortices can also form at the intersection of the flaps and ailerons if the flaps are down, most strongly at partial flap, they can be even stronger than a clean wing tip vortice at high speed.
Disregard on the vortex then. It looks great!
