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…
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…
Intermittency in Interplanetary Coronal Mass Ejections Observed by Parker Solar Probe and Solar Orbiter
Julia Ruohotie, Simon Good, Christian Möstl +1
Intermittency has been studied extensively in the fast and slow solar winds but to a far lesser extent in interplanetary coronal mass ejections (ICMEs). While ICMEs are often chara…
Effect of interplanetary shock waves on turbulence parameters
Emilia Kilpua, Simon Good, Juska Soljento +6
We have performed an extensive statistical investigation of how interplanetary fast forward shocks affect certain turbulence parameters, namely, the cross-helicity, , residual…
Permutation Entropy and Complexity Analysis of Large-scale Solar Wind Structures and Streams
Emilia Kilpua, Simon Good, Matti Ala-Lahti +2
In this work, we perform a statistical study of magnetic field fluctuations in the solar wind at 1 au using permutation entropy and complexity analysis, and the investigation of th…
Validity of using Elsässer variables to study the interaction of compressible solar wind fluctuations with a coronal mass ejection
Chaitanya Prasad Sishtla, Jens Pomoell, Norbert Magyar +2
Alfvénic fluctuations, as modelled by the non-linear interactions of Alfvén waves of various scales, are seen to dominate solar wind turbulence. However, there is also a non-neglig…
Classification of Enhanced Geoeffectiveness Resulting from High-Speed Solar Wind Streams Compressing Slower Interplanetary Coronal Mass Ejections
Stephan G. Heinemann, Chaitanya Sishtla, Simon Good +2
High-speed solar wind streams (HSSs) interact with the preceding ambient solar wind to form Stream Interaction Regions (SIRs), which are a primary source of recurrent geomagnetic s…
