研究実績の概要

BATSRUS+RAM-SCB simulations of the EMIC wave-particle interactions during the 27 May 2017 storm were used to understand the evolution of waves in the inner magnetosphere, their correspondence to the proton precipitation into the subauroral ionosphere. The performance of the model in reproducing the EMIC wave-particle interactions were also assessed. The simulations reproduced the proton precipitation observed in the dusk-midnight sector by the DMSP/NOAA MetOP satellites fairly well. The model qualitatively captured the growth of the EMIC waves during the storm and showed that the EMIC waves, by scattering the ring current, were responsible for the proton precipitation into the dusk-midnight sector during the storm.
