英文摘要In this letter, the statistical characteristics of the structures of giant undulations (GUs) during geomagnetic storms are studied for the first time, based on aurora images during 2005-2019. The GUs mainly occur within similar to 4 h following the beginning of the storm main phase and finish in +/- 4 h around the storm peak. The most interesting feature is that the anti-sunward edge of GUs is quasi-stable (18-19 h MLT) during their lifetime. The latitudinal amplitudes of GUs (A(GU)) peak at 200-300 km while the azimuthal wavelengths (W-GU) occupy several discrete values between 100 and 900 km. Both A(GU) and W-GU are quasi-proportional to the strength of the storms, and A(GU) is also proportional to W-GU. There are some differences in the characteristics of A(GU) and W-GU between pre- and post dusk sectors. These results would provide both statistical insight for mechanisms of dynamic auroral structures and data sources for validating magnetosphere-plasmasphere-ionosphere coupling models.
