Spectral properties of mesoscale fluctuations in interplanetary coronal mass ejections

Anna-Sofia Jylhä, Simon Good, Emilia Kilpua

Magnetic fields in interplanetary coronal mass ejections (ICMEs) often display a flux rope structure at large scales and a turbulent cascade of fluctuations at smaller scales. Howe…

Radial and angular evolution of magnetic cloud signatures in the turbulent solar wind: virtual spacecraft analysis

M. Sangalli, E. K. J. Kilpua, A. Verdini +3

Interplanetary coronal mass ejections (ICMEs) carry magnetic clouds (MCs), large-scale structures with average radial widths about a fifth of an astronomical unit at Earth's orbit.…

The Correlation Length of Turbulence in Magnetic Clouds

S. W. Good, J. Lalueza Puértolas, A. -S. M. Jylhä +1

The large-scale limit or outer scale of turbulence in the solar wind is associated with the correlation length of the magnetic field. Determining correlation lengths from magnetic…

Spatio-Temporal Evolution of the March 2022 ICME Revealed by Multi-Point Observations of Forbush Decreases

Gaku Kinoshita, Beatriz Sanchez-Cano, Yoshizumi Miyoshi +13

Interplanetary coronal mass ejections (ICMEs) cause Forbush Decreases (FDs) effects, which are local decreases in background galactic cosmic rays (GCR). Even though FDs can be obse…

Exploring Complexity Measures for Analysis of Solar Wind Structures and Streams

Venla Koikkalainen, Emilia Kilpua, Simon Good +1

In this paper we use statistical complexity and information theory metrics to study structure within solar wind time series. We explore this using entropy-complexity and informatio…

Residual energy of magnetohydrodynamic shocks

S. W. Good, K. J. Palmunen, C. H. K. Chen +5

Residual energy quantifies the difference in energy between velocity and magnetic field fluctuations in a plasma. Recent observational evidence highlights that fast-mode interplane…
