Evans (1993) argued that it is important to examine the degree to which the model vortices have physical similarities with real TCs. Here we present the structure of the simulated TC. Figure 2 shows the horizontal and vertical structures of several quantities in a TC simulated in the model. In common with observed TCs, there is low sea level pressure accompanied by cyclonic circulations with stronger surface winds on the right hand side (Figs. 2a and b). The surface wind speed at 10 m exceeds 20 m s-1. The cyclonic circulations of the model TCs extend up to near 200 hPa (Fig. 2c), with warm cores from 700 hPa to 200 hPa (Fig. 2d). Although the model used in the present study cannot simulate the eye wall structure because of the insufficient resolution, the above features of the simulated TC are in reasonable
agreement with the observations (e.g., Frank 1977) and the model TC simulated in other GCM (e.g., Wu and Lau 1992; Tsutsui and Kasahara 1996; Vitart et al. 1997).
