Heliospheric Energetic Particle Flux Variations

  • Chapter

Abstract

Energetic particles in the heliosphere represent a mixture of populations accelerated at the Sun, in various regions of the inner and outer heliosphere, and in galactic sources. Suprathermal and energetic particles usually play a minor role in the mass, momentum and energy density carried by the solar wind at 1 AU, although they are likely to have more important dynamical effects at very small and very large heliospheric radii. The intensity distribution of the highly variable interplanetary energetic particle component of solar-heliospheric origin will be discussed for various energies and for different levels of solar activity. Particular attention will be given to very low-flux and very high-flux periods. Low-flux periods may also be important for the study of ‘clean’ cases of magnetospheric acceleration. Expected long-term variations of high-fluence events and their terrestrial effects will also be discussed.
