Numerical models: A tool for investigating ocean circulation

An increasing need exists for quantitative studies of the circulation of the world ocean. The hydrodynamic equations with a suitable Reynolds averaging to eliminate very Small scale motion may be used to analyze the very extensive data on the temperature and salinity structure of the ocean which have been gathered by oceanographic expeditions. Hydrodynamic models may also be useful in planning future surveys as well as predicting the formation of large scale temperature anomalies in the ocean which are believed to be an important influence on world fisheries and year to year variations in weather.
