Global mode decomposition is applied to high speed jets over a range of jet-to-ambient density ratios and Mach numbers. Maximal transient response was obtained for each system by computing an optimal superposition of non-normal global modes. The non-normality of the global modes increased with decreasing density ratio as well as decreasing Mach number.
