The book Zonal Jets: Phenomenology, Genesis, and Physics will be published by Cambridge University Press at the end of February.  The book collects papers on zonal jets from across disciplines (atmospheric science, oceanography, planetary science, geophysical fluid dynamics, plasma physics, magnetohydrodynamics, and  turbulence
theory). The book is edited by Boris Galperin (University of South Florida) and Peter L Read (University of Oxford).  Chapter 12 is a paper on “General results on zonation in rotating systems with a β-effect and the electromagnetic force” by Bin Cheng and Alex Mahalov (Arizona State University).  You can order the book by following the above link.
