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