Report of the Workshop on Assimilation of Satellite Wind and Wave Data in Numerical Weather and Wave Prediction Models

摘要

The assimilation of microwave data in atmospheric and wave models, and the relation between on-line data assimilation systems and quick-look and off-line analysis facilities were discussed. The assimilation system should provide gridded data of surface winds, surface stresses, surface fluxes of sensible and latent heat, and surface waves, using all the sensor data of oceanographic satellites with all other available conventional and (meteorological) satellite data. The generation of a multiyear, continuous time sequence of gridded surface stress and heat flux fields is essential for climatological studies. Since the data assimilation requirements of climate and forecasting applications are essentially identical, and most of the required data are routinely collected at forecasting centers, it is practical to implement the data assimilation system at global weather forecasting centers. Numerical experiments which can be carried out with SEASAT data to develop and test integrated data assimilation methods were identified.
