Why does wake turbulence seem to move upward on touchdown? Source of the first photo

I saw this photo of business jet touching down (first picture) and the smoke of tires forming wake turbulence . as I have provided other pictures (second and third) of "what we have seen and know about the theory of wake turbulence" , you can see this strange upside down form of wake turbulence . simply what is the reason ?

This is not wake turbulence. This is a hard landing. The smoke from the tires is hot, it rises, hits the fuselage, curls away from it, and then curls back on itself due to the Rayleigh–Taylor instability.

(YouTube) A more persistent example. Note the still rising column of smoke.
