Turbulent flows subject to the Coriolis force are examined theoretically to study thevortex dynamo or generation of large-scale turbulent structures. A major term in theturbulent vortex-motive force that plays a key role in the mean vorticity equation isshown to be proportional to the angular velocity vector of a rotating system with theproportional coefficient expressed in terms of the helicity. This result shows that thevortical structure with its axis in the zonal direction near the equator is a promisingcandidate of Saturn's large atmospheric structures called white spots. Formation ofthe vortex with its axis normal to the spherical surface, as in typhoons, is also dis-cussed.
