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…
Radial Diffusion Driven by Spatially Localized ULF Waves in the Earth's Magnetosphere
Adnane Osmane, Jasmine Sandhu, Tom Elsden +2
Ultra-Low Frequency (ULF) waves are critical drivers of particle acceleration and loss in the Earth's magnetosphere. While statistical models of ULF-induced radial transport have t…
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…
Linear, Quasi-Linear and Nonlinear Radial Transport in the Earth's Radiation Belts
Adnane Osmane, Emilia Kilpua, Harriet George +2
Observational studies of the Earth's radiation belts indicate that Alfvénic fluctuations in the frequency range of 2-25 mHz accelerate magnetically trapped electrons to relativisti…
Imbalanced Turbulence Modified by Large-scale Velocity Shears in the Solar Wind
Juska E. Soljento, Simon W. Good, Adnane Osmane +1
We have investigated how the degree of imbalance in solar wind turbulence is modified by large-scale velocity shears in the solar wind plasma. The balance between counterpropagatin…
Cross helicity of interplanetary coronal mass ejections at 1 au
S. W. Good, L. M. Hatakka, M. Ala-Lahti +3
Interplanetary coronal mass ejections (ICMEs) contain magnetic field and velocity fluctuations across a wide range of scales. These fluctuations may be interpreted as Alfvénic wave…
