Intermittent character of interplanetary magnetic field fluctuations
Physics of Plasmas, 2007 Interplanetary magnetic field magnitude fluctuations are notoriously more intermittent than velocity fluctuations in both fast and slow wind. This behavior has been interpreted in terms of the anomalous scaling observed in passive scalars in fully developed hydrodynamic turbulence.

On an interplanetary magnetic field [PDF]
Journal of Geophysical Research, 1955 Considerations suggesting the existence of an interplanetary magnetic field are presented. Such a field would not exceed about 5×10−8 gauss, and its presence can explain the observed cutoff in the primary cosmic-ray momentum spectrum. A field existing within the earth's orbit can account for all or part of the observed solar-terrestrial time delays in ...

Directional discontinuities in the interplanetary magnetic field [PDF]
Solar Physics, 1969 It is shown that the interplanetary magnetic field has different characteristics on different scales, and it is noted that a given physical theory may not be applicable or relevant on all scales. Four scales are defined in terms of time intervals on which the data may be viewed.

The Astrophysical Journal, 2023 In this work, we extend Leighton’s diffusion model describing the turbulent mixing of magnetic footpoints on the solar wind source surface. The present Lagrangian stochastic model is based on the spherical Ornstein–Uhlenbeck process with drift that is ...

Formation of a strong southward IMF near the solar maximum of cycle 23 [PDF]
Annales Geophysicae, 2004 We analyzed observations of the solar activities and the solar wind parameters associated with large geomagnetic storms near the maximum of solar cycle 23.

Relationship of Transport Coefficients with Statistical Quantities of Charged Particles
The Astrophysical Journal, 2023 In previous studies, a general spatial transport equation was derived from the Fokker–Planck equation. The latter equation contains an infinite number of spatial derivative terms T _n = κ _nz ∂ ^n F /∂ z ^n with n = 1, 2, 3, ⋯ .

Active Regions and the Interplanetary Magnetic Field [PDF]
Symposium - International Astronomical Union, 1968 The relation of solar active regions to the large-scale sector structure of the interplanetary field is discussed. In the winter of 1963–64 (observed by the satellite IMP-1) the plage density was greatest in the leading portion of the sectors and lesser in the trailing portion of the sectors. The boundaries of the sectors (places at which the direction

Energetics of Shock-triggered Supersubstorms (SML < −2500 nT)
The Astrophysical Journal, 2023 The solar wind energy input and dissipation in the magnetospheric–ionospheric systems of 17 supersubstorms (SSSs: SML < −2500 nT) triggered by interplanetary shocks during solar cycles 23 and 24 are studied in detail. The SSS events had durations ranging
