Understanding how these and other electromagnetic modes nonlinearly saturate is likely critical in understanding the confinement of a high $\\beta$ spherical tokamak (ST). Equilibrium $E\\times B$ sheared flows have sometimes been found to significantly suppress low $\\beta$ ion scale transport in both gyrokinetic simulations and in experiment. This work aims to understand the conditions under which $E\\times B$ sheared flow impacts on the saturation of MTM simulations.
