Short summary
Short summary
We have collected statistics of 81 fast plasma flow events in the magnetotail with clear MMS observations of kinetic Alfven waves (KAWs). We show that KAWs electric field magnitudes correlates with thermal/subthermal electron flux anisotropy: wider energy range of electron anisotropic population corresponds to higher KAWs’ electric field intensity. These results indicate on an important role of KAWs in production of thermal field-aligned electron population of the Earth’s magnetotail.

Short summary
Short summary
In the paper we study flapping wave structures, generated in the neutral plane of the Earth magnetotail. Investigated flapping is an important process of magnetosphere dynamics, connected with magnetic energy transformation and magnetic storm formation. Large separation of Cluster spacecraft allows us to estimate both local and global properties of flapping current sheets, the typical flapping times and propagation directions.

Short summary
Short summary
Earth's bow shock in solar wind with high thermal and low magnetic pressure is a rare phenomenon. However, such an object is ubiquitous in astrophysical plasmas.
We surveyed statistics of such shock observations since 1995. About 100 crossings were initially identified. In this report 22 crossings from the Cluster project were studied using multipoint analysis, which allowed for the determination of the spatial scales of the shock transition and of the dominant magnetic variations

Short summary
Earth's bow shock in high beta (beta is ratio of thermal
to magnetic pressure) solar wind environment is rare phenomenon.
We survey statistics of beta > 10 shock observations.
Typical solar wind parameters related with high beta are: low speed, high density and very low IMF 1–2 nT.
In this report 22 crossings are studied with spacecraft
separation within 30–200 km. Dominating magnetic waves have frequency 0.1–0.5 Hz Polarization has no stable phase
and is closer to linear.
