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