Chorus waves, which cause the acceleration and loss of energetic electrons within the inner magnetosphere, play an essential role in cross-energy coupling. Investigating the temporal-spatial variations of chorus waves in the inner magnetosphere necessitates a global simulation that incorporates the non-linearity of chorus waves. In this study, we simulated the dynamics of energetic electron distributions and the plasmasphere using the RAM-SCBE simulation [Jordanova et al., 2014], which accurately models the evolution of the electron distribution function and density of thermal plasma under self-consistent magnetic fields. Using the simulated distribution functions, ambient density and magnetic fields provided by the RAM-SCBE, we conducted self-consistent electron hybrid simulations [Katoh et al., 2018] to investigate the generation of chorus elements, including chorus bursts, and to examine how the ambient plasma distribution function and fp/fc control the non-linear characteristics of whistler mode waves during storm time. We also compare with the Arase observed plasma waves and electron distributions with the simulation.
