Description

Recent results of high-resolution MHD calculation of solar convection zone will be shown. Higher-resolution calculations enable us to investigate the efficient small-scale dynamo in the solar global convection zone. In our highest resolution, efficient small-scale dynamo is excited throughout the convection zone and magnetic field can reach almost equipartition strength. The Lorentz feedback to the thermal convection is significant. In the talk, possible influence from small-scale dynamo to energy transport, differential rotation and large-scale dynamo is discussed.
