The dynamical winds of Classical T Tauri stars (CTTS) are believed to originate from the MHD processes at the boundary between the inner disc and the stellar magnetosphere. We explore how the wind affects the circumstellar dusty environment. Long term spectroscopic and photometric monitoring of the CTTS RY Tau in 2013-2015 has revealed a tight correlation between the wind radial velocity and the circumstellar extinction. 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 suggest that cyclic re-adjustments of the stellar magnetosphere and the subsequent magnetospheric mass ejections can have an impact on the dusty disk wind flows near the inner boundary of the circumstellar disk. A role of dusty winds in the long-lasting dimming events in CTTS is discussed.
