Abstract:

The goal of this project is to understand the fundamental dynamics of interactions between tropical cyclone TC and large-scale low-frequency circulation such as the monsoon gyre MG over the western North Pacific WNP. Through its interaction with low-frequency flow, TC may experience unusual track change and intensity change. The project is to conduct an observational analysis to identify the impact of low-frequency motion on TCs in the WNP during the past decade 2000-2011, and to conduct idealized and real-case numerical model simulations to understand the impact of the low-frequency motion on TCs. It is anticipated that successful completion of this project would lead to advance of our current understanding of TC-low-frequency flow interaction, which may help improve current operational TC forecast skill.
