My newest plume video:

This model setup uses a heavily-modified MITgcm tutorial_deep_convection test case. Some highlights:

• Resolution: $4$ m $\times$ $4$ m $\times$ variable in the vertical ($1$ m at the surface to $11$ m at depth)
• Domain: $594$ $\times$ $33$ $\times$ $99$ grid cells (9 cores)
• Initialisation: Temperature and salt profile from mooring time series (24 h mean starting from noon on September 12, 2021)
• Initial velocities are $0$ m s$^{-1}$ in all directions
• Timestep: $4$ s
• Equation of state: TEOS-10
• Coriolis: $f_0=-1.358 \times 10^{-4}$, $\beta=8.194 \times 10^{-12}$
• Boundary conditions: no_slip_bottom and no_slip_sides are both .FALSE., with no tracer relaxation sponges
• Surface forcing: Constant heat flux of -$200$ W m$^{-2}$ and a salt flux following Stefan’s law for the first 24 h, then forcings ceased for the last 12 h
• Surface temperature limitation (i.e., allowFreezing=.TRUE.): Tfreezing=-1.9 (i.e., a wee bit of supercooling)
• Non-hydrostatic solver: cg3dMaxIters=40
• Advection scheme: tempAdvScheme and saltAdvScheme are both $33$ (and diffusivities are all $0$)
• Viscosity: Three dimensional Smagorinsky scheme with default coefficient
