  1. Paper ReviewOne-Dimensional Sea Ice-Ocean Model Applied to SHEBA Experiment in 1997-1998 WinterWen-Yih Sun and Jiun-Dar Chern Wen-Ien

  2. Introduction • SHEBA: The Surface Heat Budget of the Arctic Ocean • The model includes 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.

  3. 1. One-Dim. Mixed-Layer Ocean Model a. (Salinity) (Density) b. (Energy) c. 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.

  4. a.Sanity ( ) 1. 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.

  5. b. Density ( ) 1. : the density of sea water, = 1000 and = 273.15 K. 2.

  6. c.Energy ( ) 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: .

  7. c.Energy 5. H is the heat flux inside the seawater. Downward Shortwave Radiation Sensible Heat Flux Latent Heat Flux Heat Transfer of Precipitation albedo Upward and Downward Longwave Radiations Eddy Heat Flux

  8. c.Energy :wind speed near surface;
