Observations of the solar photosphere show spatially-compact large-amplitudeDoppler velocity events with short lifetimes. In data from the ImagingMagnetograph eXperiment (IMaX) on the first flight of the Sunrise balloon in2009, events with velocities in excess of 4{\sigma} from the mean can beidentified in both intergranular downflow lanes and granular upflows. We showthat the statistics of such events are consistent with the random superpositionof strong convective flows and p-mode coherence patches. Such coincidentsuperposition has implications for the interpretation of acoustic wave sourcesin the solar photosphere, and may be important to the interpretation ofspectral line profiles formed in solar photosphere.
