Dritschel, D.G. & Ambaum, M.H.P. 1997 A contour-advective semi-Lagrangian algorithm for the simulation of fine-scale conservative dynamical fields. Q.J.R. Met. Soc. 123, 1097-1130 (journal)

The CASL algorithm is developed and demonstrated using a multi-layer quasi-geostrophic model in a domain that is double periodic in the horizontal.

Dritschel, D.G., Polvani, L.M. & Mohebalhojeh, A.R. 1999 The contour-advective semi-Lagrangian algorithm for the shallow water equations. Mon. Weather Rev. 127, 1551-1565 (journal)

The CASL algorithm is developed for the shallow water equations.

Mohebalhojeh, A.R. & Dritschel, D.G. 2004 Contour-advective semi-Lagrangian algorithms for many-layer primitive equation models. Q.J.R. Met. Soc. 130, 347-364 (journal)

This paper describes various CASL algorithms for the f-plane primitive-equation models and compares them in detail with a standard pseudo-spectral algorithm as regards their representation of balance and imbalance in complex vortical flows with substantial activity in small horizontal and vertical scales.

Smith R. & Dritschel, D.G. 2006 Revisiting the Rossby-Haurwitz wave test with contour advection. J. Comp. Phys. 217 (2), 473-484 (journal)(preprint)

Two CASL varieties are demonstrated with the Rossby-Haurwitz test case.
