We have calculated the velocity distribution of wind driven by Alfvin waves. The assumed initial number density of wind can affect the line profiles because it produces the change in the velocity distribution under the mass conservation. Initial density N0 = 5.5 x 1012/cm3 is chosen for a proper initial density from the observation by Schroder(1986). The wind models for N0 = 109, 1010, 1011, 5.5 x 1012/cm3 are calculated at ©ª = 0.06 and ©ª = 0.78. The line profiles for lower initial density show the strong emissions and narrow absorptions because of their steeper velocity gradients.
