Abstract: We study AGN emission line profiles combining an improved version of the accretion disk wind model of Murray & Chiang (1997) with the magnetohydrodynamic (MHD) model of Emmering et al. (1992). We find that the shape, broadening and shift of the C IV line depend not only on the viewing angle to the object, but also on the wind launch angle. We have compared the dispersions in our model C IV linewidth distributions to the observed upper limit on that dispersion found by Fine et al. (2008, 2010). We have considered both an opaque torus of fixed half-opening angle and the physically motivated obscuration model of Mor et al. (2009). As the torus half-opening angle increases above about 18°, increasingly larger wind launch angles are required to match the Fine et al. constraints. Above a half-opening angle of about 47°, no wind launch angle can match the observations.
