辽东湾海冰生消的热力要素分析

利用辽海湾ＪＺ２０－２海域冰斯气象、水文和海泳的测量资料，对冰面太阳辐射、长波辐射、盛热、潜热、冰内热传导和泳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泳期的海８泳热力要素进行了对比分析，发展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，疳直接影响到冰面潜热

Thermodynamic analysis during sea ice growth in the Liaodong Bay

The calculation methods of sea ice heat fluxes are presented considering the charecteristics of the Bohai sea ice firstly, Based on the hydrological, meteorological and sea ice data observed on the JZ20 - 2 platform in the Liaodong Bay, some parameters of thermodynamics model were determined. From the heat fluxes calculated under the different weather conditions and at different date, the influences of meteorological factors were analyzed, and the air temperature, the oceanic heat flux and the solar radiation control the growth and decay of sea ice. Through the thermodynamics analysis of the Bohai sea ice, some mechanisms of sea ice growth are understood deeply, which may be significant to the sea ice numerical simulation.
