Accuracy and stability of the discretised isopycnal-mixing equation

Primary tabs

Mathieu, PP Deleersnijder, Eric [UCL]

Coarse-grid ocean models parameterise the effects of mesoscale eddies by means of a mixing operator which diffuses tracers along surfaces of constant potential density, called isopycnals. We establish the consistency conditions, the spatio-temporal accuracy error and the computational stability conditions for the small-slope isopycnal mixing operator. (C) 1999 Elsevier Science Ltd.
