Solar wind acceleration by the dissipation of Alfven waves

Axford and McKenzie [1992] suggested that the energy released in impulsive reconnection events generates high frequency Alfven waves. The kinetic equation for spectral energy density of waves is derived in the random phase approximation. Solving this equation we find the wave spectrum with the power law "-1" in the low frequency range which is matched to the spectrum above the spectral brake with the power low "1.6." The heating rate of solar wind protons due to the dissipation of Alfven waves is obtained.
