w_damping

damp_opt = 0, ; upper level damping flag

0 = without damping

1 = with diffusive damping, maybe used for real-data cases

(dampcoef nondimensional ~0.01-0.1)

2 = with Rayleigh damping

(dampcoef inverse time scale [1/s]

e.g. .003; idealized case only

not for real-data cases)

3 = with w-Rayleigh damping

(dampcoef inverse time scale [1/s]

e.g. .05;

for real-data cases)

dampcoef (max_dom) = 0., ; damping coefficient (see above)

zdamp (max_dom) = 5000., ; damping depth (m) from model top

w_damping = 0, ; vertical velocity damping flag (for operational use)

0 = without damping

1 = with damping
