Role of the upper ocean in medium and extended range forecasting

A Workshop on the Role of the upper ocean in medium and extended range forecasting was held at ECMWF on 13 to 15 November 2002.

Description

The ocean plays an important role in seasonal forecasting. The best known process is El Nino with its origins in the tropical Pacific where air-sea interaction is strong, but there is evidence emerging of partly predictable phenomena in the Atlantic and Indian oceans also. At shorter time scales, ocean-atmosphere interaction may be important in for example tropical storm prediction and the intraseasonal oscillation. With developments in the ocean observation system and in data assimilation and modelling, the potential for making and using upper ocean forecasts has improved substantially.

This meeting covered 4 main themes:

  • Discussion of significant phenomena which involve air/sea coupling on the timescales from hours to months.
  • The use of ocean forecasts on these timescales.
  • New methods of observing the ocean and challenges in assimilating data in ocean models.
  • Recent advances in ocean and ice modelling and requirements for further progress.
