Measurements of the time-varying cross-sectional mean liquid holdup for vertical upward huge wave and annular flows were made simultaneously at 269 axial locations with a spacing of 5 mm. Typical time-spatial maps of wave behavior are presented. Close inspection of these results reveals that a disturbance wave has usually a single peak, except during the absorption and discharge of waves, whereas a huge wave always has several peaks. Fully developed disturbance waves move not only with a nearly constant velocity, but with nearly the same shape. In contrast to this, the shapes of huge waves change considerably with time. Four patterns for ware behavior are discussed. Short lived huge waves and disturbance waves are found.
