The sequence shows the evolution of dynamic structures resembling tornadoes in the solar atmosphere. The blue and green color scheme shows the vorticity in the solar atmosphere in the regions where solar tornadoes appear. The plane shows the magnetic field strength about 1Mm below the solar surface where $\tau=1$. One can clearly see that the vorticities are closely related to the subsurface magnetic field.

Further information:
The visualization was done using VAPOR.
