Description of the Book:

A full numerical model of the typhoon with rigid constraints on the divergence, vorticity and surface pressure fields was tested and found capable of producing realistic forecasts of typhoon development. The constraints on these fields are that the fields are subject to Laplace’s equation in both spiral and circular cylindrical coordinates. The zero Laplacian constraint is compatible with a full scale model of the typhoon. Experiments on the role of the Richardson number, critical entrophy and eddy viscosity show their necessity in the creation and maintenance of the separate typhoon regimes. The asymmetric contributions account for the major portion of the divergence and vorticity budgets. New numerical techniques which bypass finite differencing account for significant reduction in storage requirements and in computational time. (Author
