Two exciting methods for the incorporation of neutral sheet drift into two-dimensional cosmic-ray modulation models are evluated, and compared to a method which uses an explicit neutral sheet drift velocity field. It is shown how the latter may be adapted to simulate the effect of a wavy neutral sheet, and results from this model are compared with 27 day averaged results from a full three-dimensional model.
