The split explicit integration scheme for the barotropic primitive equation model is investigated for the stability and accuracy. The governing equations are divided into two sets:advective equations and adjustment equations. The integration cycle is split into two main steps. First, the advective equations are integrated explicitly, and then the adjustment equations are integrated explicitly. It is proved that the split explicit integration scheme is in more stability than the explicit integration scheme. For the limited-area barotropic primitive equation model the computing time required for this scheme to produce 24-hour forecasts is only half of that for the explicit scheme.
