stresses_3d - bottom and surface stresses (Source File: stresses_3d.F90)

INTERFACE:

    subroutine stresses_3d

DESCRIPTION:

As preparation of the call to do_turbulence in the routine gotm, see section 8.13.15, the normalised surface and bottom stresses, $\tau_s/\rho_0$ (variable taus) and $\tau_b/\rho_0$ (variable taub), respectively, are calculated and interpolated to the T-points. Input parameters to this routine are rru and tt rrv, which contain $r\sqrt{u^2+v^2}$ for the U- and V-points, respectively. The modules of the surface and bottom stress vectors are calculated then by means of taking the square root of the sum of the squares of the stess components. In a similar way also the $x$- and $y$-components of the bottom stress are computed for output. USES:
