Abstract 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.

太阳风湍流:与高能粒子的联系

摘要 对于太阳风,大量的观测证据表明,湍流是速度(v)、磁(b)和其他相关 MHD(流体)尺度波动的重要动力学过程。在这里,我们回顾了这些观察结果和湍流特征,包括讨论波浪或湍流描述何时可以(或不能)解释这些观察结果。强调了 MHD 湍流特性与高能粒子的加速和传输的相关性。概述了不同类别的太阳风波动模型,然后回顾了 (i) 太阳风波动和 (ii) 宇宙射线的传输模型。关于宇宙射线传输模型,宇宙射线传输系数方面的最新进展,以及它们在宇宙射线调制模型中的应用,
