3D Vortices in Rotating, Stratified Flows in the Lab, Ocean, Planetary Atmospheres and Protoplanetary Disks

A common assumption concerning vortices in the ocean and atmosphere is that their “aspect ratios”, defined as their characteristic vertical thicknesses divided by their average diameters, are functions only of the vertical stratification (or Rossby deformation radius, or Brunt-Vaisala frequency N) of the surrounding fluid and of the local Coriolis parameter f, and not on any of the properties of the vortices themselves such as their Rossby numbers, diameters, or the internal stratifications within the vortices. In particular, the common assumption is that the aspect ratio is f/N. Our simulations, lab experiments and analyses show that this assumption is false and can be off by factors of 10-100. We have determined the proper scaling law for the aspect ratio. Our results have implications for planetary vortices, where the vertical thickness cannot be directly measured and is often inferred (incorrectly) by the f/N assumption. Understanding the physics that determines the vertical thickness is a needed first step in determining the stability of 3D vortices. In addition, understanding and being able to correctly compute the vertical aspect ratio of vortices is necessary for our current project of determining the secondary (meridional and vertical) circulations within vortices. The latter are important to understand vertical and horizontal transport within a vortex and also within an ocean or atmosphere filled with vortices. For example, a detailed knowledge of the secondary circulations is important to understand color changes in the vortices of Jupiter (i.e., its Great Red Spot), the accumulation and agglomeration of dust into planetesimals in protoplanetary disks and the vertical transport of carbon dioxide from the ocean surface to greater depths.
