Outline of Final Research Achievements

The purpose of this study is the understanding of the mechanisms of coronal heating and solar wind acceleration. For the purpose, we have been developing an ideal MHD simulation of inner heliosphere based on observations of the Sun (that is named SUSANOO) and a new MHD simulation coupled with a transport model of MHD turbulence that includes nonlinear interaction with global MHD structures. We compare the predicted turbulence distribution results from a complete solar minimum model with in situ measurements made by the Helios and Ulysses spacecraft, finding that the synthetic profiles of the turbulence intensities show reasonable agreement with observations.
