The equations developed by Riehl 1963 for a steady, symmetrical hurricane are used to specify a vortex over a fixed depth boundary layer, which interacts with a simple ocean model. Only vertical mixing in the surface layer is included in the oceanic portion of the model. Interaction of the atmosphere and the ocean occurs through the prediction of boundary layer parameters. Comparison of the predicted boundary parameters with observed mature tropical storms shows good agreement for all variables except the specific humidity, which exceeds saturation. Two attempts to correct for this situation have shown the proportion of the water vapor transported out of the top of the boundary layer without adding latent heat to the boundary layer appears to be an important factor in determining the intensity of a steady-state hurricane. Although the ocean model is quite simple, realistic horizontal oceanic temperature profiles with respect to the hurricane center were obtained. Author
