A PV Perspective on the Vertical Structure of Mature Midlatitude Cyclones in the Northern Hemisphere
Journal of the Atmospheric Sciences
Development of extratropical cyclones can be seen as an interplay of three positive potential vorticity anomalies: an upper-level stratospheric intrusion, low-tropospheric diabatically produced potential vorticity (PV), and a warm anomaly at the surface acting as a surrogate PV anomaly. This study, based on the interim ECMWF Re-Analysis (ERA-Interim) dataset, quantifies the amplitude of the PV anomalies of mature extratropical cyclones in different regions in the Northern Hemisphere on adoi:10.1175/jas-d-11-050.1 fatcat:s4pl6pjvvnaihfahxjbjlkq2ie
