“…Although the typhoon bogus creates typhoon vortex quite realistically, the vortex does not seem to be exactly adjusted for the JM-AGCM. Kurihara et al (1993) and Bender et al (1993) pointed out that an insufficient initial typhoon vortex leads to a false spin-up for the first one or two days to adjust the initial typhoon structure by a finer resolution model; similarly, our forecast experiments with the typhoon bogus also showed a false spin-up in the early forecast stage, which was remarkably observed with intensity.…”

“…Hence, the typhoon bogus was applied in this study. To avoid such a spin-up, Kurihara et al (1993) introduced an optimum initialization system to generate a vortex which is compatible with the physics and the highresolution model. However, improving the typhoon vortex in the initial condition is beyond the scope of this study and will be a challenging task for the future.…”

“…In the first, the vortex in the analysis field is entirely replaced (vortex replacement), and in the second, TC wind profiles are derived from TC best track information (wind retrieval) and assimilated. For example, the JMA's operational model (Ueno 1995), and the Geophysical Fluid Dynamics Laboratory (GFDL) model, run at NCEP (Kurihara et al 1993), use the replacement strategy, while the United Kingdom Meteorological Office (UKMO) (Heming et al 1995) and the Navy Operational Global Atmospheric Prediction System (NO-GAPS), run by the US Navy (Fiorino et al 1993), use the retrieval approach.…”

“…In order to understand how TOMS ozone made an impact on the track prediction of Hurricane Erin, the differences of steering flow between CTRL and OZ are first examined. For the steering flow calculation, the deep layer mean is first derived using the following formula (Carr and Elsberry, 1990;Velden and Leslie, 1991): Second, the environmental flow is extracted from the mean flow by removing its vortex component using the Geophysical Fluid Dynamics Laboratory (GFDL) scheme (Kurihara et al, 1993). Finally, the steering flow is obtained by averaging the environmental flow within a radius of 500 km from the storm centre.…”
