Abstract

In this study, the evolution and structure of tropical cyclone Vamei (2001) were simulated using the version 3.6 of the fifth generation of the Pennsylvania State University and the National Center for Atmospheric Research non-hydrostatic model MM5 using one-way nesting and two nested grids. The parameterizations employed include the subgrid-scale convective parameterization of Kain- Fritsch, the grid resolvable Schultz microphysics scheme, the Blackadar parameterization scheme for planetary boundary layer processes, and the CCM2 radiation scheme. The model was initialized and bound by the NCEP global final analyses. The model was integrated for 36 h with an analysis nudging technique employed in the first domain throughout the integration. The second domain was initialized 12 h later with the initial and boundary conditions interpolated from the first domain. The model performed reasonably well in reproducing the track, minimum central pressure, surface maximum sustained wind speed and cloud distribution. During the 36 h of integration, the model clearly shows the evolutionary stages of rapid deepening, maximum intensity, landfall and rapid weakening. The simulated system intensified into a typhoon about 15 h into the model integration time. The thermodynamic and precipitation structures of the simulated system during maximum intensity clearly showed the eye, eyewall, and spiral rainbands. Sensitivity tests indicate that both the sea surface heat transfer and the release of latent heat in clouds contribute positively to the cyclogenesis. Rapid weakening occurred once the system made landfall and there was no longer any latent heat supply from the sea surface.
