Experiments Of The Numerical Simulation Of Typhoons

Marilyn C. De Guzman

This paper is an attempt to simulate the development of typhoons by solving the hydrodynamic equations of the atmosphere using numerical methods. The essential features of the study involve the use of cylindrical pressure coordinate system under the assumption of symmetry, and use of primitive equations. The effect of cumulus clouds is parametized as proposed by Ooyama (1964) where the latent heat released in a vertical column of air is specified by the horizontal mass convergence in the friction layer. Further, the distribution of heat in the vertical is proportional to the temperature difference between cumulus clouds and the large-scale field (Kuo, 1968).
