Influence of Regional Climate Modes on Tropical Cyclone Development

The aim of this study is to detect how climate variability within the Southwest Pacific and Indian Ocean regions affects tropical cyclogenesis in the Australian region. Section 2 describes the data and methods, section 3 details a statistical analysis of the tropical cyclone best track data. Section 4 explains the results from a wavelet power spectrum of SST indices and of various TC regions while section 5 examines correlations between the filtered peaks from the wavelet analysis and compares this data to the seasonal frequency of tropical cyclones and the locations of TCG. Finally section 6 finally provides some conclusions and future work.
