【英文摘要】Ground-based visible aurora data observed from Zhongshan station, Antarctic, and Yellow River station, Arctic, and UV images captured from satellites were selected for comparison to study the “aurora hot spots” phenomena and their conjugate/non-conjugate characteristics. We conclude that the “aurora hot spots” found on UV images are corresponding to the vortex structures in the aurora arc captured by the ground-based aurora imagers, and provide an explanation for the “aurora hot spots” creation mechanism: The MHD surface wave induced by the K-H instability could convert to the kinetic Alfvén wave (KAW), the KAW then generates parallel electric field to excite the multiple arcs in the postnoon aurora oval. The velocity drifts, perpendicular to the direction of the magnetic field, of the particles precipitating along the multiple arcs causes the flow shear. Influenced by the K-H instability in the flow shear, the vortex structure in the aurora arcs can be formed. Such vortex structures appear as the form of bright spots (namely the aurora spirals) in the view of satellite UV imagers. The conjugate/non-conjugate characteristics of “aurora hot spots” are influenced by the IMF By component: the “aurora hot spots” cannot be occurred simultaneously in the both hemisphere when |By|>>|Bz|; and only occur in southern hemisphere when By>0, in northern hemisphere when By<0; during |By|～|Bz| condition, the “aurora hot spots” can be found simultaneously in both hemisphere. We also found that the increases of high energetic proton flux observed at the geostationary orbit satellite are well corresponded to the aurora movements and vortex structures of aurora captured at Yellow River station.
