We present, for the first time, the probability density function (PDF) of ionospheric vorticity measurements made by the SuperDARN HF radars. We show that the PDF is typically heavy-tailed and best modelled by the q-exponential distribution across most of the ionosphere, except in the dayside region 1 current region where the Weibull distribution provides the best model. We identify these distributions as stationary solutions of a Fokker-Planck equation whose corresponding Langevin equation can be derived from the classic baroclinic and barotropic vorticity equations, respectively.
