The long-time behavior of nonlinear Landau damping is investigated by numerically solving the Vlasov-Poisson system. The period and strength of the trapped electron oscillations are considered in detail. The results are interpreted in terms of a simple weighted-average oscillator model that takes into account of the dominance of shallowly trapped electrons.
