Case analysis of the relationship between propagating disturbances (PDs) and Hα jet. Snapshot showing the connection between Hα jets in the NVST Hα − 0.6 Å (B) and PDs in the filtered AIA 171 Å (A). The yellow arrow outlines the structures of PDs determined from panel A, while the blue arrow represents the associated Hα jets from panel B. Time-slice images of the PD is shown in panel C. The blue lines mark the locations of PDs. Panel D and E: maximum height and ascending velocity of the Hα jets which exist in the footpoint of the given PD. Those denoted by the red arrows are those presented prior to the PD. See animation online.
