| Abstract: | It is necessary to determine the parameters of thermodynamics and dynamics in sea ice numerical model precisely for accurate forecasting sea ice. The solar radiation plays a key role in thermal processes as well affects other thermal factors such as the long wave radiation and convective heat flux. Based on the field observations on the JZ20-2 platform in Liaodong Bay, the influences of atmosphere and cloud cover on solar radiation during freezing periods in this area are discussed. The optical air mass is 0.83 in the winter of Liaodong Bay, and the cloud coefficients can be selected as 0, 3, 6, 8, 9 and 10 under the weather conditions of clear sky, partly cloudy, cloudy, overcast sky, fog and rain respectively. The reflection of solar radiation on mixed ice-water region is also discussed. The analysis of thermodynamic calculation shows that the solar radiation influences the long wave radiation and sensitive heat of the ice surface, and it is the controlling factor during the growth and melting of sea ice. The precision of sea ice simulation and forecast can be improved if the computational methods of solar radiation in the ice season are adopted in the sea ice numerical model of the Bohai Sea. |
