Powerful solar complexes of activity are supposed to result from the excitation of Rossby vortices within a thin layer beneath the convection zone. Numerical simulations demonstrate that Rossby vortices generate large‐scale arc‐like magnetic structures. It is shown that the most powerful complex of activity observed in June‐July 1982 was likely to be a result of the excitation of a Rossby anticyclone rather than a cyclone.
