| 1 | Optical and SuperDARN radar observations of duskside shock aurora over Zhongshan Station显示文摘We present observations of a duskside shock aurora occurred on 21 April 2001 by the SuperDARN radar at Syowa Station and the all-sky camera at Zhongshan Station (ZHS) in Antarctica when the radar was operated in fast-scan mode covering the ZHS region. With the two independent data sets, we examine ionospheric plasma convection and aurora arising from a sudden impulse (SI) event associated with an interplanetary shock. During the transient shock compression, the aurora was quiescent without any optical emission at the preliminary impulse of the SI. About 7 min later, a new thin auroral arc with brighter emissions and a lifetime of~14 min expanded westward from the region above ZHS during the main impulse of the SI. SuperDARN radar line-of-sight measurements showed periodical oscillation in the flow direction with ultra-low-frequency waves having a period of~8 min during the shock compression. We suggest that downward field-aligned current during the preliminary impulse stage of the SI was the main driver of the first plasma flow reversal, and the subsequent new discrete auroral arc may be associated with field-aligned acceleration in the region of the main impulse related upward field-aligned currents. The ground magnetometer observations suggest that the oscillation of the ionospheric convection on the duskside was associated with field line resonance activity. | LIU Jianjun HU Hongqiao HAN Desheng LIU Yonghua ZHANG Qinghe Akira S Yukimatu | 2013 | Advances in Polar Science2013，24，1： | 2 |
| 2 | Chinese Antarctic Magnetometer Chain at the Cusp Latitude显示文摘A Chinese Antarctic Magnetometer(CAM) chain from Zhongshan Station(ZHS) to Dome-A(DMA) has been established since February 2009.A regular magnetometer is operated at ZHS,and four low power magnetometers are operated along the interior route from ZHS to DMA in the cusp latitude,extending over a distance of 1260 km.These stations fill an important void in the Antarctic magnetometer network.Furthermore,the CAM chain is magnetically conjugated with the Arctic region reaching from the Svalbard archipelago to Daneborg,on the east coast of Greenland.Conjugate measurements using the Arctic and Antarctic magnetometers provide excellent opportunities to investigate phenomena related to the coupling of the solar wind to the magnetosphere and ionosphere,such as magnetic impulse events,flux transfer events,traveling convection vortices and ultra-low frequency waves. | LIU Yonghua HU Hongqiao YANG Huigen ZHANG Beichen SUN Bo WEI Fuhai LIU Yang LIU Jianjun WANG Rui CHEN Zhuotian HU Zejun HAN Desheng SHI Guitao HU Zhengyi WANG Tao AN Chunlei Mike Rose | 2016 | Advances in Polar Science2016，27，2： | 2 |
| 3 | Simultaneous optical and radar observations of poleward moving auroral forms under different IMF conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers at Chinese Yellow River Station in the Arctic, together with the EISCAT Svalbard radar (ESR) and SuperDARN radars, we investigated the dayside poleward moving auroral forms (PMAFs) and the associated plasma features in the polar ionosphere under different interplanetary magnetic field (IMF) conditions, between 0900 and 1010 UT on 22 December 2003. Simultaneous optical and ESR observations revealed that all PMAFs were clearly associated with pulsed particle precipitations. During northward IMF, particles can precipitate into lower altitudes and reach the ionospheric E-region, and there is a reverse convection cell associated with these PMAFs. This cell is one of the typical signatures of the dayside high-latitude (lobe) reconnection in the polar ionosphere. These results indicate that the PMAFs were associated with the high-latitude reconnection. During southward IMF, the PMAFs show larger latitudinal motion, indicating a longer mean lifetime, and the associated ionospheric features indicate that the PMAFs were generated by the dayside low-latitude reconnection. | XING Zanyang YANG Huigen HAN Desheng WU Zhensen LIU Junming HU Zejun ZHANG Qinghe LIU Yonghua ZHANG Beichen HU Hongqiao | 2012 | Advances in Polar Science2012，23，4： | 2 |
| 4 | Dayside poleward moving auroral forms and ionospheric convection under stable interplanetary magnetic field (IMF) conditions显示文摘Using high temporal resolution optical data obtained from three-wavelength all-sky imagers over six winters continuously at Yellow River Station (78.92°N,11.93°E) in Arctic,we statistically investigated the dependence of location of poleward moving auroral forms (PMAFs) on the interplanetary magnetic field (IMF) B z and B y components as a function of MLT and MLAT under stable IMF conditions.It is found that more PMAFs occurred in lower latitude for Bz<0 and there was less evident IMF B y-related prenoon-postnoon asymmetry for Bz<0 than for Bz>0.We found that the PMAFs were distributed over a wide range of MLT when Bz<0,which indicates that the reconnection X-line might spread like an 'S' shape.However,during northward IMF,PMAFs were observed predominantly prenoon for IMF By>0 and postnoon for IMF By<0 associating with the effect of the high-latitude reconnection,which is largely consistent with the theoretical model of the convection flow. | XING ZanYang YANG HuiGen HAN DeSheng WU ZhenSen LIU JunMing HU ZeJun ZHANG QingHe HU HongQiao LIU YongHua | 2013 | Science China(Technological Sciences)2013，56，4： | 2 |
| 5 | Interplanetary shock-associated aurora显示文摘Interplanetary shocks or solar wind pressure pulses have prompted impacts on Earth's magnetospheric and ionospheric environment, especially in causing dynamic changes to the bright aurora in the polar ionosphere. The auroral phenomenon associated with shock impingements, referred to as shock aurora, exhibits distinct signatures differing from other geophysical features on the dayside polar ionosphere. Shock aurora provides a direct manifestation of the solar wind–magnetosphere–ionosphere interaction. Imagers onboard satellites can obtain the associated large-scale auroral characteristics during shock impingement on the magnetopause. Therefore, auroral data from satellites are very useful for surveying the comprehensive features of shock aurora and their general evolution. Nonetheless, the ground-based high temporal-spatial resolution all-sky imagers installed at scientific stations play an essential role in revealing medium-and small-scale characteristics of shock aurora. Here, we focus on shock aurora imaging signatures measured by imagers onboard satellites and ground-based all-sky imagers. | LIU Jianjun HU Hongqiao HAN Desheng YANG Huigen | 2019 | Advances in Polar Science2019，30，1： | 1 |

| 10 | Effect of interplanetary shock on an ongoing substorm:Simultaneous satellite-ground auroral observations显示文摘Substorm processes have been studied in detail,and it is well known that interplanetary(IP)shock encountering the terrestrial magnetosphere causes global responses.However,how IP shock compression to the magnetosphere affects the development of an ongoing substorm remains uninvestigated.Herein,the simultaneous satellite and ground-based auroral evolutions associated with an IP shock impact on the magnetopause during an ongoing substorm on May 7th,2005,were examined.The IMAGE satellite over the Southern Hemisphere captured the global development substorm,which was initiated at 17:38:47 UT.The poleward branch of the nightside auroral oval was fortuitously monitored by an all-sky camera at the Zhongshan Station(-74.5°magnetic latitude,ZHO)in Antarctica.The satellite imager observed continuous brightening and broadening of the nightside auroral oval after the IP shock arrival.The simultaneous ground-based optical aurora measurement displayed the intensification and expansion of a preexisting auroral surge poleward of the aurora oval.The geomagnetic field variations and the instantly increased PC indices indicated an elevated merging rate and enhanced the convection-related DP-2 currents.Therefore,this IP shock transient impact did not significantly change the ongoing development of the substorm,although it meets the magnetospheric precondition hypothesis. | LIU JianJun CHEN XiangCai WANG ZhiQiang HU ZeJun ZHAO XingXin HU HongQiao HAN DeSheng LUI A.T.Y | 2023 | Science China(Technological Sciences)2023，66，3： | 1 |
