  X-ray obscuration of active galactic nuclei (AGNs) is considered in the
context of ionized winds of stratified structure launched from accretion disks.
We argue that a Compton-thick layer of a large-scale disk wind can obscure
continuum X-rays and also lead to broad UV absorption such as in the blue wing
of Civ; the former originates from the inner wind while the latter from the
outer wind as a dual role. Motivated by a number of observational evidence
showing strong AGN obscuration phenomena in Seyfert 1 AGNs such as NGC 5548, we
demonstrate in this work, by utilizing a physically-motivated wind model
coupled to post-process radiative transfer calculations, that an extended disk
wind under certain physical conditions (e.g. morphology and density) could
naturally cause a sufficient obscuration qualitatively consistent with UV/X-ray
observations. Predicted UV/X-ray correlation is also presented as a consequence
of variable spatial size of the wind in this scenario.
