We consider a solution of the incompressible Navier–Stokes equations in R³, related to the singular complex solutions of Li and Sinai [e20094-LiSi08], and such that a growth of the enstrophy S(t) is expected. The computer simulations show that S(t) increases up to a time T_E (singularities are excluded by axial symmetry). They also reveal an interesting “tornado-like'' behavior, with a sharp increase of speed and vorticity in an annular region, as for some “extreme'' weather phenomena. DOI: 10.31857/S0044451020080167
