Abstract
This review of the Office of Naval Research Tropical Cyclone Motion Research Initiative was prompted by the decision to terminate aircraft reconnaissance in the western North Pacific region, which eliminated a key component of the planned field experiment. Expanded opportunities for theoretical studies of tropical cyclone motion were suggested in terms of more representative environmental structures and physical processes. Concurrent experimentation with state-of-the-art numerical models was also recommended, especially for environmental conditions related to western North Pacific tropical cyclones. A review of existing observational data sets for testing hypotheses indicated that all except the University of Wisconsin, satellite-derived fields were already being studied Thus, it was concluded that a need exists for additional data sets, perhaps through deployment of recently developed dropwindsondes or of an array of wind profilers and the exploitation of satellite microwave imagers and sounders. Concerns regarding the feasibility of such a field experiment are related to lack of operational reconnaissance, availability of aircraft platforms for deploying the dropwindsondes and the need for international cooperation. The recommendation of the review group was to pursue further the possibilities for a reduced, but highly focused, field experiment. If the above concerns cannot be satisfactorily resolved within the budget limitations, expand the scope of the theoretical, numerical modelling and observational studies to exploit those opportunities to the fullest extent possible. The recommended mechanism to facilitate progress would be to establish a center for tropical cyclone motion studies.
