The authors consider the non-autonomous 2D Navier-Stokes equations with nonslip boundary condition for ,
where is the velocity vector field, is the pressure, is the kinematic viscosity. Along with (1) the averaged Navier-Stokes equations are considered
Under suitable assumptions on the external force, the uniform boundedness of the related uniform global attractors is established for the equations (1). is the attractor to the equations (2). It is proved that converge to as in the standard Hausdorff semidistance in the space .
