  The wind interaction with the dusty environment of the classical T Tauri star
RY Tau has been investigated. During two seasons of 2013-2015 we carried out a
spectroscopic and photometric (BVR) monitoring of the star. A correlation
between the stellar brightness and the radial velocity of the wind determined
from the H-alpha and Na D line profiles has been found for the first time. The
irregular stellar brightness variations are shown to be caused by extinction in
a dusty disk wind at a distance of about 0.2 AU from the star. We suppose, that
variations of the circumstellar extinction results from cyclic rearrangements
of the stellar magnetosphere and coronal mass ejections, which affect the dusty
disk wind near the inner boundary of the circumstellar disk.
