    Abstract

    Records of storms in the North Sea are analyzed for evidence that wave groups may be composed of independently propagating components. The Stockwell transform (S-Transform) is used to obtain time-frequency contour plots of wave energy for simulated idealized, interacting wave groups. Additionally, simulated groups with independent directional components, are analyzed using both the S-transform and the Iterative Maximum Likelihood Method to resolve the directions and frequency. Both techniques are applied to the analysis of North Sea storm data obtained from a 3-point array showing that real wave groups can be formed of interacting components that may be propagating in different directions.
