[SH016] On the reduction of cosmic-ray drift coefficients in the presence of turbulence


  • Nicholas Eugene ENGELBRECHT

Primary authors



Drift effects have long been known to play a significant role in the transport of charged particles in the heliosphere. A turbulent magnetic field is also known to reduce the effects of particle drifts. The exact nature of this reduction, however, is not clear. This study aims to provide some insight into this reduction, and proposes a relatively simple, tractable means of modelling it that provides results in reasonable agreement with numerical simulations of the drift coefficient in a turbulent magnetic field. Furthermore, we investigate the spatial dependences of this new turbulence-reduced drift coefficient, using the results of a two-component turbulence transport model as inputs where required, along with a comparison with turbulence-reduced coefficients proposed in previous studies.
