    • Effective Stratification for Pseudoadiabatic Ascent 
      Nielsen-Gammon, John; Keyser, Daniel (American Meteorological Society, 2000-08-01)
      Effective stratification can be interpreted as the resistance to upward motion of saturated air parcels experiencing condensation. Previously published expressions for effective stratification conflict with each other, and ...
    • A Potential Vorticity Diagnostic Approach to Upper-Level Frontogenesis within a Developing Baroclinic Wave 
      Wandishin, Matthew; Nielsen-Gammon, John; Keyser, Daniel (American Meteorological Society, 2000-12-15)
      The process of tropopause folding is studied in the context of the life cycle of baroclinic waves. Previous studies of upper-level frontogenesis have emphasized the role of the vertical circulation in driving stratospheric ...
