15.1.6 vmix1d.F

File vmix1d.F executes vertical mixing schemes in a simple one dimensional model (depth versus time). Currently, it will exercise option ppvmix which is the scheme based on Pacanowski/Philander (1981) or option kppvmix which is the scheme based on Large, McWilliams, and Doney (1994) depending on which one is set in the run script run_vmix1d. Script run_vmix1d exercises this module in stand alone mode by enabling option test_vmix and ppvmix or kppvmix. The driver uses a simplified 1-D equation configuration with Coriolis and vertical diffusion terms at a specific latitude to indicate how mixing penetrates vertically. The 1-D equations are

$$\partial_tu - fv \partial_z(\kappa_m\cdot\partial_z(u))$$ = (15.24)

$$\partial_tv + fu \partial_z(\kappa_m\cdot\partial_z(v))$$ = (15.25)

$$\partial_tT \partial_z(\kappa_h\cdot\partial_z(T))$$ = (15.26)

with values of $\kappa_m$ and $\kappa_h$ being predicted by the enabled scheme. Refer to Section 32.2.4 for details of the scheme.
