A Global Solar Wind Model Based on Surface Measurements of Magnetic Field and Transverse Velocity from GONG
Abstract
We present a solar wind model based on a three-dimensional (3D) data-driven, time-dependent, magnetohydrodynamic (MHD) model. The inputs to the model are the measured line-of-sight (LOS) magnetic field of SOLIS and transverse velocity from the Global Oscillation Network Group (GONG) on the lower boundary without heating and momentum additions. The results show that both slow and fast components of the solar wind are produced without arbitrarily specifying additional heating and momentum due to the employment of multiple sets of observations. In addition, the global distribution of the coronal holes responsible for the formation of co-rotating interaction regions (CIRs) is also consistently presented.
