The presented project implies the study of small scale turbulence in the solar wind by means of theoretical research of kinetic Alfven wave turbulence and solar wind data analysis. In particular, for an explanation of the high-frequency solar wind observations, we intend to develop a model of kinetic Alfven wave turbulence which will include active turbulent cascade and kinetic dissipation at the same time. We will also study the influence of imbalance between kinetic Alfven waves propagating along and backwards with respect to the background magnetic field on energy cascade features of the turbulence. We plan to test various theoretical predictions (both obtained in the framework of this project and belonging to alternative models) analyzing high-frequency spectra of the solar wind magnetic field and plasma parameters.
