Abstract

Estimations are presented concerning the contribution of MHD waves propagating from the low boundary of chromosphere-corona transition layer in the energy balance of magnetically open outer solar atmosphere. The corresponding energy-momentum sources are shown to be sufficient for coronal heating and solar wind acceleration. Selfconsistent model of wave driven solar corona and solar wind is constructed, in the frame of which the locations of coronal temperature maximum and solar wind transonic region coincide with the regions of effective wave damping. Wave energy flux into the corona is controlled by the value of magnetic field induction at the coronal base, and the wave energy distribution into the main channels of losses is determined by the magnetic field structure in the inner and middle corona.
