Abstract

This thesis investigates genesis pathways of tropical cyclones (TCs) over the North Atlantic basin during 2004-2008 with a focus on TCs that form in conjunction with extratropical precursor disturbances. These genesis pathways are nonbaroclinic, low-level baroclinic, trough-induced, transient-trough interaction, weak tropical transition (TT), and strong TT. The transient-trough interaction, trough-induced, weak TT, and strong TT genesis pathways all occur in conjunction with extratropical precursor disturbances. This thesis will assess the physical and dynamical mechanisms relevant to TC genesis among these genesis pathways via composite and case study analyses.
