Operational Forecasts (MUMM)

  1. A hydrodynamic model describes the distribution of three-dimensional currents and the height of the surface of the sea. This takes account of the influence of the moon and the stars on the movement of the water as well as the effect of the meteorological conditions (wind and pressure). At the moment it provides forecasts over a period of five days corresponding to the availability of meteorological forecasts. It is primarily used in the alarm mechanisms triggered in the event of a storm and provides various forms of navigation assistance in coastal waters.
  2. A second model describes the distribution of waves in the North Sea. With the help of meteorological forecasts, it also operates in forecasting mode. It takes account of the phenomenon of wave refraction in shallow waters in coastal areas. This wave model helps to guide large vessels into buoyed channels and can be useful for recreational sailors.
  3. A third model describes the movement, spreading and physical and chemical development of pollutants on the surface of the sea, particularly hydrocarbons. It is used in every critical or accidental situation to determine the potential impact of pollution and provide support for the decisions to be taken in the operations to fight pollution.

These models are inter-linked. This means that the information obtained from one model is used as input data for another. For instance, currents calculated by a hydrodynamic model are used to predict the movement of oil slicks.
