Abstract

We discuss the present status of our understanding of the transport and acceleration of anomalous cosmic rays and the transport of galactic and CIR-accelerated particles in the heliosphere. Currently, two-and three-dimensional numerical codes can accurately model many of the observed phenomena - with the major current uncertainties being the values of the parameters such as the diffusion coefficients and the effects of the poorly understood structure beyond the termination shock. We illustrate the nature of the phenomena by discussing in detail the response of energetic particles to co-rotating interaction regions, the acceleration of singly-and multiply-charged anomalous cosmic rays, and the effects of galactic cosmic rays on the structure of the solar wind and its termination shock.
