Geostrophic turbulence near rapid changes in stratification

  title={Geostrophic turbulence near rapid changes in stratification},
  author={K. Shafer Smith and Etienne Bernard},
Geostrophic turbulence near horizontal surfaces on which the vertical velocity vanishes exhibits a forward cascade of buoyancy variance, characterized by a shallow energy spectrum, secondary roll-up of filaments, and a fat-tailed vorticity probability distribution. Such surfaces occur at rigid boundaries, but also at discontinuous jumps in stratification… CONTINUE READING
