Abstract

A typhoon bogussing and relocation algorithm, based on the MM5 3D-Var cycling system, was developed. The bogus sea-level pressure and wind fields were assimilated into the MM5 3D-Var analyses in the cycling mode. The scheme was tested with the Typhoon Rusa (2002) case. It was observed that the MM5 numerical simulations using the 3D-Var bogussing initialization showed a skillful forecast of Typhon Rusa near landfall. It was also observed that the typhon bogussing algorithm was able to generate realistic warm-core temperature structure, through the dynamical and statistical balance constraints internal to the 3D-Var system.
