A method for operating a wind turbine includes operatively coupling a fluid container within the wind turbine. The fluid container is in flow communication with an air distribution system at least partially defined within a blade of the wind turbine. The method further includes channeling a fluid from the fluid container into the air distribution system, and discharging the fluid from the air distribution system through at least one aperture of the air distribution system defined through an outer surface of the blade to facilitate removing debris from the air distribution system.
