mom_isopycnal_slopes module reference¶
Calculations of isoneutral slopes and stratification.
Functions/Subroutines¶
Calculate isopycnal slopes, and optionally return other stratification dependent functions such as N^2 and dz*S^2*g-prime used, or calculable from factors used, during the calculation. |
|
Returns tracer arrays (nominally T and S) with massless layers filled with sensible values, by diffusing vertically with a small but constant diffusivity. |
