英文摘要	The formation of typhoon durian (2001) was simulated well by the weather research and forecasting model. the vorticity field was separated into three scales: small scale (l < 30 km), intermediate scale (30 km < l < 120 km), and system scale (l > 120 km), where l is wavelength. during the formation, small-scale vorticity anomalies, associated with convection, aggregated radially inward and rotated anticlockwise. the system-scale vorticity field presented a distinct mid-level vortex before genesis, and then a well-organized low-level vortex. the spectral power of the low-level vorticity at the small scale barely changed, while that at the system scale continued to grow steadily. the vorticity growth or spin-up of the near-surface tropical cyclone embryo was mainly due to the convergence of vertical vorticity flux at the planetary boundary layer. the positive (negative) effect of vorticity flux convergence at lower (middle-to-upper) levels appears to cause the shift of system-scale vorticity center from the middle to lower troposphere.
