A parameterization of new ice formation in a wave field has been developed. Detailed processes of new sea ice growth with multiple ice types (nilas, grease, and pancake ice) and associated wave attenuation by different sea ice types are presented and implemented into a coupled ROMS and SWAN model. Sea ice formation includes growth and transformation of frazil, grease, pancake, nilas and solid ice. Ice types are determined by thermal condition and the wave fields. Simultaneously, the attenuation of wave energy through the ice cover is dependent on ice types. The two processes are coupled by COAWST. The resulting coupled model is applied to the Bohai Sea. When compared with in-situ data from oil platforms, the model performed well in distinguishing solid ice, pancake and nilas. When compared with previous ice models without the consideration of new ice types, the appearance of solid ice is delayed, the total ice area and ice volume are increased, solid ice thickness is increased while the type-averaged thickness is reduced and heat flux from the ocean to air is increased during the freezing phase. By considering the new ice formation, wave attenuation in the test case is enhanced.

已经开发了波场中新冰形成的参数化。在耦合 ROMS 和 SWAN 模型中呈现并实现了具有多种冰类型（nilas、油脂和薄饼冰）的新海冰生长的详细过程以及不同海冰类型的相关波衰减。海冰的形成包括 frazil、油脂、薄饼、nilas 和固体冰的生长和转化。冰的类型由热条件和波场决定。同时，通过冰盖的波浪能衰减取决于冰类型。这两个过程由 COAWST 耦合。所得耦合模型应用于渤海。与石油平台的原位数据相比，该模型在区分固体冰、薄饼和尼拉斯方面表现良好。与之前未考虑新冰类型的冰模型相比，固体冰的出现延迟，总冰面积和冰量增加，固体冰厚度增加，而类型平均厚度减少，来自冰种的热通量增加。在冻结阶段，海洋对空气的增加。通过考虑新的冰形成，增强了测试案例中的波浪衰减。
