| Summary: | The area between the continental shelf and the Gulf Stream is known as the slopewater region. In the past fifty years several experiments and studies of this region have taken place with the Mid-Atlantic Continental Slope and Rise (MASAR) experiment being one of the most recent. Csanady and Hamilton (1988) compiled all the known information and data from the slopewater region and developed a simple dynamic model of the flow. Based on this model's transport stream function and Stommel's Gulf Stream model, finite centered differencing was used to develop a numerical scheme of slopewater circulation. The model was first developed using Stommel's parameter for circulation within the North Atlantic Gyre. Stommel's model was used as the basis for the new scheme in order to calibrate the model with his exact solution of the stream function for the North Atlantic Gyre. Once verified, Stommel's parameters were replaced by Csanady and Hamilton's values for slopewater. This is a report on the development of a new numerical model. It is also a comparison of the new scheme to both Csanady and Hamilton's model and an observational schematic for the region from the MASAR experiment. |
