| 7 | !! History : NEMO 4.0 ! A. Grant, G. Nurser |
|---|
| 8 | !! 15/03/2017 Changed calculation of pycnocline thickness in unstable conditions and stable conditions AG |
|---|
| 9 | !! 15/03/2017 Calculation of pycnocline gradients for stable conditions changed. Pycnocline gradients now depend on stability of the OSBL. A.G |
|---|
| 10 | !! 06/06/2017 (1) Checks on sign of buoyancy jump in calculation of OSBL depth. A.G. |
|---|
| 11 | !! (2) Removed variable zbrad0, zbradh and zbradav since they are not used. |
|---|
| 12 | !! (3) Approximate treatment for shear turbulence. |
|---|
| 13 | !! Minimum values for zustar and zustke. |
|---|
| 14 | !! Add velocity scale, zvstr, that tends to zustar for large Langmuir numbers. |
|---|
| 15 | !! Limit maximum value for Langmuir number. |
|---|
| 16 | !! Use zvstr in definition of stability parameter zhol. |
|---|
| 17 | !! (4) Modified parametrization of entrainment flux, changing original coefficient 0.0485 for Langmuir contribution to 0.135 * zla |
|---|
| 18 | !! (5) For stable boundary layer add factor that depends on length of timestep to 'slow' collapse and growth. Make sure buoyancy jump not negative. |
|---|
| 19 | !! (6) For unstable conditions when growth is over multiple levels, limit change to maximum of one level per cycle through loop. |
|---|
| 20 | !! (7) Change lower limits for loops that calculate OSBL averages from 1 to 2. Large gradients between levels 1 and 2 can cause problems. |
|---|
| 21 | !! (8) Change upper limits from ibld-1 to ibld. |
|---|
| 22 | !! (9) Calculation of pycnocline thickness in unstable conditions. Check added to ensure that buoyancy jump is positive before calculating Ri. |
|---|
| 23 | !! (10) Thickness of interface layer at base of the stable OSBL set by Richardson number. Gives continuity in transition from unstable OSBL. |
|---|
| 24 | !! (11) Checks that buoyancy jump is poitive when calculating pycnocline profiles. |
|---|
| 25 | !! (12) Replace zwstrl with zvstr in calculation of eddy viscosity. |
|---|
| 26 | !! 27/09/2017 (13) Calculate Stokes drift and Stokes penetration depth from wave information |
|---|
| 27 | !! (14) Buoyancy flux due to entrainment changed to include contribution from shear turbulence. |
|---|
| 28 | !! 28/09/2017 (15) Calculation of Stokes drift moved into separate do-loops to allow for different options for the determining the Stokes drift to be added. |
|---|
| 29 | !! (16) Calculation of Stokes drift from windspeed for PM spectrum (for testing, commented out) |
|---|
| 30 | !! (17) Modification to Langmuir velocity scale to include effects due to the Stokes penetration depth (for testing, commented out) |
|---|
| 31 | !! ??/??/2018 (18) Revision to code structure, selected using key_osmldpth1. Inline code moved into subroutines. Changes to physics made, |
|---|
| 32 | !! (a) Pycnocline temperature and salinity profies changed for unstable layers |
|---|
| 33 | !! (b) The stable OSBL depth parametrization changed. |
|---|
| 34 | !! 16/05/2019 (19) Fox-Kemper parametrization of restratification through mixed layer eddies added to revised code. |
|---|
| 35 | !! 23/05/19 (20) Old code where key_osmldpth1` is *not* set removed, together with the key key_osmldpth1 |
