Abstract
Waves and sea ice form a closely coupled system: waves govern sea ice through stress, floe break-up, and wave-induced currents, while sea ice affects waves through attenuation and reflection. Wave-induced sea ice break-up is particularly important as it can regulate air-sea interaction and consequently also regulate the growth and melt of sea ice. This coupled nature is complex and generally, especially at the large scale, neglected in modeling of the polar climate system. Here, we explore a novel way of coupling through wave-induced ice break-up, and conduct a case study for the Antarctic summer of 2019/2020. Our modeling approach builds upon previous investigations as follows: (a) sea ice ..
