1. a mixed-layer ocean model,
( used to predict water temp., salinity, density, and
turbulent kinetic energy )
2. a multi-layer snow/ice model,
( used to predict the thickness, temp., and heat transfer of
snow/sea ice )
and the interfaces among atmosphere, snow/sea ice, and sea water.
The equations for a one-dimensional ocean model, which include 27 layers.
S: salinity, Δz: layer-thickness, ρ:density, T: water temperature,
c: the specific heat capacity.
Here k-1/2 and k+1/2 stand for the value at the top and bottom of the k- layer.
2. is the eddy flux and is derived from .
: the eddy coefficient
3. : the Newtonian forcing for salinity.
1. : the density of sea water, = 1000 and
= 273.15 K.
1. is the specific heat capacity of sea water.
2 . : the Newtonian forcing for temperature.
3. : the net latent heat released from freezing or melting.
: is the mass loss (gain) due to freeze (melt) at the open
water surface or ice-water interface.
are precipitation rate for rain and snow.
is the new fallen snow density.
4. The freezing point of seawater: .
5. H is the heat flux inside the seawater.
