Description

The DWD World Wave model is a global model, generating wave information, including wind waves and swell.

This model, unlike the NOAA WW3 model, also includes information on the Mediterranean. There is however higher resolution Mediterranean information available, by using the DWD Europe model.

Ocean wave forecasts based on DWD-Model ICON

Since July 2015, DWD provides forecasts of worldwide ocean winds and waves as a basic service for the public in order to support safety of shipping and life at sea. The numerical wave model represents an integral part of the operational weather prediction system. Therefore, wave forecasts directly depend on the forcing by analyzed and forecast 10m-winds of the atmospheric model ICON.

Internally, the wave model describes the local sea state as a 2-dimensional distribution of wave energy with respect to wave period and the direction of propagation. In the present version, a wave spectrum represents 36 directions und 30 wave periods from 1.5 to 24 seconds.
