In line with the first three parts, this part contains a further set of research papers which focus on numerical modelling. As previously a range of topics is covered by experts from various countries. In common with Part III the problem of addressing small-scale processes, e.g. internal waves, eddies are considered early on in this part. The increasing use of non-hydrostatic models rather than the conventional hydrostatic model and grids that are fine enough to resolve internal waves and eddies suggests that models of this type will become increasingly important over the next decade. The effect of small-scale topographic features such as islands, and small-scale variations in meteorological forcing, upon the larger scale oceanic circulation is a topic of increasing importance. A detailed study of these problems is presented here. In a complimentary paper the role of sandbanks upon near bottom currents and sediment movement with an associated measurement programme is discussed. Air–sea interaction problems are examined using a process study with a single point model in the vertical, and a full three-dimensional model where hurricane induced currents in the ocean are considered. These papers on air–sea interaction illustrate the role of different types of models, namely process and simulation. Increasing interest in data assimilation methods is illustrated in the review aspect and new techniques presented here and in earlier parts. The last papers in this part deal with the development and application of unstructured grid models in a range of oceanographic problems. Again this is a growing field, which is progressing very rapidly at the moment. Besides presenting new research the papers in this series contain a review element and very importantly some discussion of future developments in their respective fields. An indication of deficiencies in present data sets and advanced measurement requirements to parallel model development is given. It is hoped that by grouping the papers together a more coherent “state of the art” is presented than is normally possible in journals.
