Drift-Alfvén waves in space plasmas – theory and mode identification

O. G. Onishchenko, O. A. Pokhotelov, V. V. Krasnoselskikh, and S. I. Shatalov

Abstract. The theory of drift-Alfvén waves with the spatial scales comparable to the ion Larmor radius is developed. The dispersion relation, the wave impedance and variations of the plasma density perturbations versus the wave frequency are investigated. The relevance of theoretical results obtained to the Cluster observations in the cusp and near a reconnection X line in the Earth's magnetopause is discussed.
