A Two-Population von Mises--Fisher Distribution of the Magnetic Field Direction in the Young Solar Wind

Gang Li, N. H. Bian, S. Y. Huang +6

The one-point distribution of the magnetic field direction in the young solar wind is found to be a superposition of two populations rather than a single exponential. Using Parker…

Complexity-entropy analysis of solar photospheric turbulence: Hinode images of magnetic and Poynting fluxes

Abraham C. -L. Chian, Haroldo V. Ribeiro, Erico L. Rempel +5

The spatiotemporal inhomogeneous-homogeneous transition in the dynamics and structures of solar photospheric turbulence is studied by applying the complexity-entropy analysis to Hi…

Deciphering Pre-solar-storm Features Of September-2017 Storm From Global And Local Dynamics

Breno Raphaldini, Mausumi Dikpati, Aimee A. Norton +4

We investigate whether global toroid patterns and the local magnetic field topology of solar active region AR12673 together can hindcast occurrence of the biggest X-flare of solar…

Direct evidence: twisted flux tube emergence creates solar active regions

David MacTaggart, Chris Prior, Breno Raphaldini +2

The magnetic nature of the formation of solar active regions lies at the heart of understanding solar activity and, in particular, solar eruptions. A widespread model, used in many…

Geomagnetic reversals at the edge of regularity

Breno Raphaldini, Everton S. Medeiros, David Ciro +2

Geomagnetic field reversals remain as one of the most intriguing problems in geophysics and are regarded as chaotic processes resulting from a dynamo mechanism. In this article, we…

Nonlinear Rossby wave-wave and wave-mean flow theory for long term Solar cycle modulations

Breno Raphaldini, André Seiji Teruya, Carlos Frederico Mendonca Raupp +1

The Schwabe cycle of solar activity exhibits modulations and frequency fluctuations on slow time scales of centuries and millennia. Plausible physical explanations for the cause of…
