| مستخلص: |
• Solar wind fluctuations involve turbulence and waves • Models for evolution of these fluctuations are in accord with observations • Cosmic ray scattering parameters depend on the fluctuation properties • Particle transport models taking account of such effects can reproduce observations For the solar wind, a wealth of observational evidence indicates that turbulence is an important dynamical process for velocity ( v ), magnetic ( b ), and other related fluctuations at MHD (fluid) scales. Here we review such observations and turbulence features, including discussion of when wave or turbulence descriptions can (or cannot) explain the observations. The relevance of properties of MHD turbulence to the acceleration and transport of energetic particles is emphasized. A summary of different classes of models for solar wind fluctuations is presented, followed by reviews of transport models for (i) solar wind fluctuations and (ii) cosmic rays. In connection with cosmic ray transport models, recent developments in terms of cosmic ray transport coefficients, as well as their application in cosmic ray modulation models, are discussed in detail.
