Continual influences of tropical waves on the genesis and rapid intensification of Typhoon Durian (2006)

Using a global cloud‐system resolving model (GCRM), we examined the external influence of tropical waves on the life‐cycle of a tropical cyclone (TC). The GCRM successfully simulated the genesis and rapid intensification of Typhoon Durian (2006). Sensitivity experiments demonstrated that the genesis of Durian was triggered by a distinct westward‐propagating tropical wave. Furthermore, the subsequent rapid intensification of Durian was affected by an eastward‐propagating tropical wave. These results not only support the tropical cyclogenesis process proposed by observational studies, but also indicates that life‐cycles of TCs may be continually influenced by several tropical waves with different origins. Thus, a GCRM is advantageous in simulating a TC genesis and the subsequent life‐cycle, in cases where a TC is influenced by external disturbances moving long distances.
