Coupled Prediction (CP-TT)

The availability of high resolution estimates of the ocean state provides the opportunity to develop high resolution coupled prediction for general weather and ocean weather applications and conduct experiments into the impact of high resolution ocean state on the coupled atmospheric, wave and oceanic states. There is also interest in exploring the impact of high resolution ocean states in seasonal forecasting systems, which currently use low resolution ocean models compared with models used for operational mesoscale oceanography.

It is therefore proposed that a working group within the ocean prediction and seasonal forecast community is best placed to drive the initial development in this form of coupled prediction.

This task team is planning to develop a clear plan that complements specific efforts being undertaken by the atmospheric and seasonal communities to explore coupled prediction and actively solicits comment and feedback and is open to contributions from and exchange between these communities where there is sufficient interest.

Objectives of the high-resolution and coupled prediction TT include:

  1. Coordinate and extend capacity within the meteorological and oceanographic community for coupled high resolution prediction systems
  2. Develop a community, from within the current meteorological and oceanographic communities, that will target high resolution coupled prediction systems to facilitate the exchange of methods for accelerated development in this application
  3. Exploit high resolution coupled prediction systems to evaluate the impact to atmospheric, wave and ocean prediction, assess the gains relative to less computationally intensive alternatives.
  4. To compile results from numerical experiments and observations regarding the impact of explicit representation of high resolution air/sea interaction on the prediction of various atmosphere and ocean phenomena at different time scales.
  5. Propose and undertake or exploit/enhance existing observational experiments to facilitate the evaluation of the impact of observations on high resolution coupled initialisation and coupled data assimilation.
