ABSTRACT
A nonlocal coupling mechanism to directly transfer the energy from large-scale magnetohydrodynamic (MHD) Alfvén waves to small-scale kinetic Alfvén waves is presented. It is shown that the interaction between a MHD Alfvén wave and a reversely propagating kinetic Alfvén wave can generate another kinetic Alfvén wave, and this interaction exists in the plasmas where the thermal to magnetic pressure ratio is larger than the electron to ion mass ratio. The proposed nonlocal interaction may have a potential application to account for the observed electron scale kinetic Alfvén waves in the solar wind and solar corona plasmas.
