An experimental investigation was conducted to describe the oscillation behavior of water droplets on solid surfaces as air flew through over the droplets, and the dynamical process was recorded using a high-speed CCD. Two liquid drop oscillation modes, forward-backward and upward-downward, and their mutual conversion were visually observed. Accounting for the internal flow and pressure distribution inside a liquid drop, a phenomenological explanation was proposed to understand the oscillation characteristics of two modes and the mutual conversion mechanisms.
