Abstract

Routine wave forecasting for the southern North Sea is performed by the Royal Netherlands Meteorological Institute (KNMI) with the numerical wave model gono (GOlven NOordzee) (Janssen et al., 1984). This model was developed by Sanders (1976) in the early 1970s based on an idea by Haug (1968). Application of the model to the southern part of the North Sea necessitated the incorporation of shallow-water effects. These extensions have been recently reported by Sanders et al. (1980, 1981). The model has been calibrated and tested in a hindcast study of several storms (cf. Sanders et al., 1980) and it has been verified for operational purposes against wave data from several positions (cf. Bouws et al., 1980a,b). Furthermore, the shallow-water results in the gono model during the winter 1979–1980 have been compared with those of the bmo model (Golding, 1978), which is operational at the British Meteorological Office (cf. Bouws et al., 1980a,b, 1981).
