Waves can drastically transform a sea ice cover by inducing break-up over vast distances in the course of few hours. However, relatively detailed studies have described this phenomenon quantitative manner, and process waves needs to be further parameterized verified before it reliably included forecasting models. In present work, we discuss parameterization demonstrate existence an observational threshold separating breaking non-breaking cases. This is based on information from two recent field campaigns, supplemented with existing observations break-up. The data used wide range scales, laboratory-grown polar observations. Remarkably, show that both laboratory tend converge single at which wave-induced takes place, opens promising avenue for robust parametrization operational
