利用辽东湾JZ2 0 2海域冰期气象、水文和海冰的测量资料 ,对冰面太阳辐射、长波辐射、感热、潜热、冰内热传导和冰下海洋热通量等热力要素的计算方法进行了讨论 ,并对其中的部分参数进行了确定 ;对 1997~1998年度不同天气条件和不同冰期的海冰热力要素进行了对比分析 ,发现太阳辐射的主要影响因素为云层 ,冰面感热主要受控于风速和气温 ,而长波辐射变化量不大 ;不同风向时的相对湿度差别很大 ,并直接影响到冰面潜热的大小 ;海洋热通量在初冰期最大 ,可达 2 0 0W/m2 以上 ,然后逐渐降低 ,在融冰期接近于 0。另外 ,气温 (冰面感热 )、太阳辐射和海洋热通量的变化决定了辽东湾海冰的生消规律。
Based on the meteorological, hydrological and sea ice data from the JZ202 sea area of Liaodong Bay, the calculation methods of solar radiation, longwave radiation, sensible heat, latent heat, heat conduction in ice and the heat flux under ice in ice are calculated Discussed and some of the parameters were determined. The thermodynamic factors of sea ice under different weather conditions and different ice ages from 1997 to 1998 were compared and analyzed. The main influencing factors of solar radiation were found to be clouds and the thermal sensation of ice surface was mainly controlled But the change of long-wave radiation is not large; the relative humidity varies greatly in different wind directions and directly affects the size of latent heat in ice; the maximum heat flux of ocean reaches up to 200 W / m2 during the initial glacial period , Then gradually decrease, approaching 0 during the melting ice period. In addition, the change of temperature (ice thermal), solar radiation and ocean heat flux determines the law of sea ice loss in Liaodong Bay.
