Statistical studies indicate that the expansion velocities of circumstellar envelopes of oxygen-rich Mira variables increase with the amplitude of 1-micron intensity variations, and possibly decrease with the stellar period for a fixed 1-micron amplitude. These correlations may be interpreted as a levitation of the atmosphere, due to stellar pulsation, out to the dust condensation point, followed by a dust-driven wind in which the gas density at the dust condensation radius plays an important role in determining the terminal expansion velocity.
