The U.S. Army Corps of Engineers (CE) tropical cyclone surface wind field model has been a very useful tool in ocean rsponse modeling fir more than a decade. Recently, its limitations were assessed in light of present knowledge and technology. Model limitations were identified and evaluates in terms of their perceived importance to ocean rrespone modeling and the level of effort required to develop improved solutions. The limitations are summarized in this report. Two aspects of the CE model were targeted for improvement. This report describes the improvements developed for the upgraded model. First, the model was upgraded to include more computationally intensive options which give improved resolution and areal coverage. Up to seven nested grids are now available, compared to only five nests in the standard model. In a typical application, this upgrade can be used to achieve 2-km resolution around the eye (as compared to 5-km resolution often used in the standard model) and an expanded total coverage area. The second upgrade allows a more general specification of the axisyrnmetric pressure profile. This upgrade can be used to create wind fields with maxima at two different radii or with a broad maximum extending over a range of radii. It also provides more flexibility in fitting the shape of single peaked wind profiles.
