Abstract

A number of experiments in dynamic initialization are carried out within the framework of a relatively simple primitive equation model. Some previously suggested variants of initialization schemes based on the Euler‐backward timestep are tested and found wanting. A new scheme is proposed, based on averaging the solutions of the primitive equations at time‐levels separated by a small interval. This scheme is tested, with encouraging results.

Theoretical considerations and experimental evidence indicate that both mass‐to‐wind and wind‐to‐mass adjustment should be catered for in a dynamic initialization scheme. This facility can easily be incorporated into the scheme proposed here, and tests confirm the advantages of doing so.

We present a three-dimensional numerical model for the shallow water equations, suitable for determining the wind driven currents in homogeneous and stratified lakes. The model is based on the semispectral primitive equation model (SPEM) originally developed by Haidvogel et al.; however, because of

The dynamic behavior of a continuous culture of Saccharomyces cerevisiae subjected to a sudden increase in the dilution rate has been successfully modelled for anaerobic growth on glucose, and for aerobic growth on acetate, on ethanol, and on glucose. The catabolism responded by an immediate jump wh
