  1. (meteorology) Not geostrophic
    • 2004, Zhu Xun, Li Xiaofan, Cai Ming, Observation, Theory And Modeling Of Atmospheric Variability, →ISBN, page 13:
      It might sound puzzling that the ageostrophic geopotential (or the ageostrophic pressure in z-coordinate) has no impact on the evolution of the vorticity of a quasi-geostrophic disturbance and yet it affects the perturbation kinetic energetics (not globally but locally).
    • 2004, James R. Holton, An Introduction to Dynamic Meteorology - Volume 1, →ISBN, page 179:
      Note that the ageostrophic wind has both a divergent and a nondivergent part.
    • 2015, Melyvn Shapiro, The Life Cycles of Extratropical Cyclones, →ISBN, page 239:
      Ageostrophic circulations play a significant role in the kinematics and dynamics of a variety of synoptic- and mesoscale weather systems found within extratropical baroclinic wave regimes.
