Abstract
Abstract The Semi-Lagrangian Inherently Conserving and Efficient (SLICE) scheme is extended to three-dimensional transport on the sphere (SLICE-3D). This paper presents details of the scheme for a longitude–latitude C-type staggering grid. The scheme is applied to a passive transport with an analytically defined wind field that can be considered as an ‘idealized climate circulation’. The performance of SLICE-3D is assessed against the widely used standard non-conservative Semi-Lagrangian (SL) scheme. The computational performance of the scheme for multiple species transport on parallel machines is also examined. Copyright © 2012 British Crown copyright, the Met Office.
