The two-dimensional structure of a supercritical perpendicular shock is investigated using a two-dimensional hybrid (particle ions and massless fluid electrons) code described by Winske and Quest (1986) to generate the shock and follow the ions. The analysis showed the relaxation of the highly anisotropic ion distribution and the corresponding growth and evolution of magnetic fluctuations. By comparing results for a low ion beta case and a high upstream ion beta case, its is shown that these effects can be understood in terms of obliquely propagating modes, likely due to the Alfven ion cyclotron instability. The observational consequences of the results and their application to improving nonlocal leakage models for the ion foreshock are discussed.
