28 | !! ** Purpose : provide the thermohaline fluxes (heat and freshwater) |
---|
29 | !! to the ocean at each time step. |
---|
30 | !! |
---|
31 | !! ** Method : Read monthly climatological fluxes in a NetCDF file |
---|
32 | !! the net downward radiative flux qsr 1 (watt/m2) |
---|
33 | !! the net downward heat flux q 2 (watt/m2) |
---|
34 | !! the net upward water emp 3 (mm/month) |
---|
35 | !! (evaporation - precipitation) |
---|
36 | !! the climatological ice cover rclice 4 (0 or 1) |
---|
37 | !! |
---|
38 | !! Qsr and q is obtained from Esbensen-Kushnir data (opal file) with |
---|
39 | !! some corrections : |
---|
40 | !! - Data are extended over the polar area and for the net heat |
---|
41 | !! flux, values are put at 200 w/m2 on the ice regions |
---|
42 | !! - Red sea and Mediterranean values are imposed. |
---|
43 | !! |
---|
44 | !! emp is the Oberhuber climatology with a function of Levitus |
---|
45 | !! salinity |
---|
46 | !! |
---|
47 | !! rclice is an handmade climalological ice cover on the polar |
---|
48 | !! regions. |
---|
49 | !! |
---|
50 | !! runoff is an handmade climalological runoff. |
---|
51 | !! |
