The fluid model was used to study the nonlinear dust drift waves in dusty plasma.Through the nonlinear interaction,the local vortex structures arise from the ultralow frequency dust electrostatic drift waves.The intensity of vortex will be closely related to the content of dusts and the ratio of the temperature between the ions and electrons.Motion of vortice across the magnetic field gives rise to the anomalous transport in plasma.
