[MITgcm-support] direct space time timestepping

[David Hebert]

The users manual shows that specifying direct space time (DST) does  
not use Adams Bashforth (AB), but rather multi-dimension stepping.  
The routines all specify the inputs as tracers. My question is since  
I can not specify a momentum advection scheme, is there a way to  
timestep momentum other than 2nd order AB? I am interested in higher  
accurate time stepping to compare a simulation of a non-hydrostatic jet.

Thanks,
David
