| Abstract: |
| Radiative fluxes are of primary importance in the energy and mass balance of the sea-ice cover.Various parameterizations of the radiative fluxes are studied in a thermodynamic sea-ice model.Model outputs of the surface radiative and heat fluxes and mass balance are compared with observations.The contribution of short-wave radiation is limited to a long part of winter.Therefore,simple schemes are often sufficient.Errors in estimations of the short-wave radiation are due mainly to cloud effects and occasionally to multi-reflection between surface and ice crystals in the air.The long-wave radiation plays an important role in the ice surface heat and mass balance during most part of a winter.The effect of clouds on the accuracy of the simple radiative schemes is critical,which needs further attention.In general,the accuracy of an ice model depends on that of the radiative fluxes. |
