English Abstract:
Terrestrial magnetosheath is the interface region between the solar wind and the Earth’s magnetosphere. The interaction between the solar wind plasma and the magnetospheric plasma results in the formation of a very complex and turbulent region associated with intensive and highly variable fluctuations in all plasma parameters. By using different approaches we attempt to identify and characterize the quasi-linear waves and coherent structures arising from the dynamical behavior of magnetosheath plasma at scales around the proton scale. The data analysis is based on Cluster spacecraft measurements.

The research leading to these results has received funding from the European Community’s Seventh Framework Programme ([FP7/2007-2013]) under grant agreement n 313038/STORM.
