چکیده
We generate a model description of the solar wind based on an explicit wave-turbulence-driven heating mechanism, and constrain our with observational data. included coronal source term in general 3D magnetohydrodynamic code NIRVANA to simulate properties wind. The adapted mechanism is interaction subsequent dissipation counter-propagating Alfv\'en waves corona, accounting for turbulent rate Q_p. magnetic field assumed be axisymmetric dipole strength 1 G. Our results are validated against data taken by Parker Solar Probe (PSP). NIRwave reconstructs bimodal structure slow fast speeds 410 km/s 650 respectively. global mass-loss 2.6e-14 masses per year. Despite implementing simplified conditions represent field, parameters characterising steady-state solution reasonable agreement previously established empirical constraints. number density from good derived constraints, larger deviations radial velocity temperature. In comparison polytropic generated NIRVANA, we find that better constraints derive.

Recent progress in astrophysical plasma turbulence from solar wind observations
This paper summarises some of the recent progress that has been made in understanding astrophysical plasma turbulence in the solar wind, from in situ spacecraft observations. At large scales, where the turbulence is predominantly Alfvénic, measurements of critical balance, residual energy and three-dimensional structure are discussed, along with comparison to recent models of strong Alfvénic tu...
متن کاملObservations of Evolving Turbulence in the Polar Solar Wind
The Ulysses magnetic field experiment has measured the heliospheric magnetic field in solar wind flows from the Sun’s Southern polar coronal hole ovef a wide range of heliolatitudes and distances. We present an anatysis of more than one ym of data, covering a latitude range of 40° to 80°S and a distance range of 4.0 to 1.7 AU. We extend an earlier analysis of Utysses magnetic field data and, by...
متن کاملA dynamical model of plasma turbulence in the solar wind.
A dynamical approach, rather than the usual statistical approach, is taken to explore the physical mechanisms underlying the nonlinear transfer of energy, the damping of the turbulent fluctuations, and the development of coherent structures in kinetic plasma turbulence. It is argued that the linear and nonlinear dynamics of Alfvén waves are responsible, at a very fundamental level, for some of ...
متن کاملA solar-wind-driven empirical model of Pc3 wave activity at a mid-latitude location
In this paper we describe the development of two empirical models of Pc3 wave activity observed at a ground station. The models are tasked to predict pulsation intensity at Tihany, Hungary, from the OMNI solar wind data set at 5 min time resolution. One model is based on artificial neural networks and the other on multiple linear regression. Input parameters to the models are iteratively select...
متن کاملModel for vortex turbulence with discontinuities in the solar wind
A model of vortex with embedded discontinuities in plasma flow is developed in the framework of ideal MHD in a low β plasma. Vortex structures are considered as a result of 2-D evolution of nonlinear shear Alfvén waves in the heliosphere. Physical properties of the solutions and vector fields are analyzed and the observational aspects of the model are discussed. The ratio of normal components t...
