According to the energy conservation theory, BOM and CSIM4 were coupled, (a) The BOM has no treatment on transmission solar radiation, which is of great importance when the model is adapted to Arctic Ocean.

• 依据能量守恒的原理，对BOM和CSIM4模式进行了耦合。 由于BOM没有考虑透射太阳辐射的物理过程，研究表明透射太阳辐射对北冰洋的能量收支起到重要作用，因此在BOM模式中引入了对透射太阳辐射的处理；
