Webscheme is a linear monotone (P) first order upwind scheme; the LDA scheme is a second order (LP) linear upwind scheme; the PSI scheme is a nonlinear second order (LP) and monotone (P) upwind scheme.
WebThe idea is to use the high-order scheme as much as one can without violating the monotonicity condition. Details can also be found in Section 5.4 of Durran's book. In the ARPS, the FCT scheme is available as an option for scalar advection – it is three to four times as expensive as a regular 1st or second advection, however.
