A non-hierarchical cluster analysis (CA) of cyclone structures in tropical cyclones undergoing extrapolation transition (ET) in the North Atlantic over the past 5 years is discussed. A synoptic composite derived using a mean path between the clusters demonstrate that the each cluster represents a distinct state of the ET process. Tropical and extratropical cyclones exhibit distinctly different frontal and thermal characteristics, so the storms reside in unique location in the cyclone phase space (CPS) making the CPS suited to investigate the evolution of cyclones. It was found that the cluster 4 contains storms with structure characteristics of both types of cyclones indicating that neither category completely describes cyclone of this type.
