- Аннотация: The numerical MHD model reproducing solar wind parameters along the orbit of Ulysses spacecraft is developed. Spatial distributions of magnetic field and plasma characteristics at distances from 20 to 1200 solar radii at almost all solar latitudes were obtained and analyzed. This model takes into account the evolution of the heliomagnetic field during the solar activity cycle, when the dominant dipole magnetic field is periodically replaced by a quadrupole one. Self-consistent solutions for principal solar wind characteristics were obtained and compared with Ulysses observations in 1990-2009 years. It is shown that the model and in situ results are in general agreement. This confirms that the model can adequately describe the general solar wind parameters. As a result it can be used for heliospheric studies of the solar wind at the different phases of the solar activity cycle. This work is supported by the grant 075-15-2020-780 (N13.1902.21.0039) of the Ministry of Science and Higher Education of the Russian Federation.
