  1. Wave parameters: H s is the significant wave height, T p the spectral peak period, T z the average zero-crossing period, z m the maximum sea surface elevation within the ST region spanning the sea surface area A and the duration D. N 3D is the theoretical number of individual 3D waves34,35,36 over the ST region of volume AD. The rogue wave strength is given by the ratio γ RW = z m/H s. For the Draupner case (labeled as Dra), z m = max{z(t) | t ∈ D}, in so far as only a time series z(t) was recorded at the platform.
