Hart and Jenni L. Evans and Clark Evans},  journal={Monthly Weather Review},  year={2006},  volume={134},  pages={553-578},  url={https://api.semanticscholar.org/CorpusID:3742254}}
Abstract A 34-member ensemble-mean trajectory through the cyclone phase space (CPS) is calculated using Navy Operational Global Atmospheric Prediction System (NOGAPS) analyses for North Atlantic tropical cyclones (TCs) undergoing extratropical transition (ET). Synoptic composites at four ET milestones are examined: 24 h prior to the beginning of ET (TB − 24), the beginning of ET (TB), the end of ET (TE), and 24 h after the end of ET (TE + 24). While the extratropically transitioning TC…
