We prove that a popular classical implicit-explicit scheme for the 2D\nincompressible Navier--Stokes equations that treats the viscous term implicitly\nwhile the nonlinear advection term explicitly is long time stable provided that\nthe time step is sufficiently small in the case with periodic boundary\nconditions. The long time stability in the L2 and H1 norms further leads\nto the convergence of the global attractors and invariant measures of the\nscheme to those of the NSE itself at vanishing time step. Both semi-discrete in\ntime and fully discrete schemes with either Galerkin Fourier spectral or\ncollocation Fourier spectral methods are considered.\n
