| 1 | 中国极区高空大气物理学观测研究进展显示文摘中国南极长城站、中山站、昆仑站和北极黄河站有着独特的地理位置,非常适合于开展极区高空大气物理学的观测研究。回顾中国极地考察研究近30年历程,综述极区高空大气物理学研究方面取得的主要进展,他们是:在南极中山站和北极黄河站建立了国际先进的极区高空大气物理共轭观测系统,实现了极区空间环境的连续监测;在极区电离层、极光和粒子沉降、极区电流体系、极区等离子体对流、地磁脉动和空间等离子体波、极区空间环境的南北极对比、极区空间天气、非相干散射雷达功率谱、电离层加热试验和极区中层夏季回波研究、极区电离层-磁层数值模拟等方面取得了一些原创性的研究成果。最后展望中国极区高空大气物理学研究的发展前景。 | 刘瑞源 杨惠根 | 2011 | 极地研究2011,23,4: | 12 |
| 2 | 南北极冬季F2层电离层特性对比研究显示文摘利用南极中山站和北极Tromso站1996、1997、1998及2002年的测高仪观测数据,对中山站(6月份)和Tromso站(12月份)上空冬季foF2的日变化特性进行了对比研究,结合数值模拟结果,分析了中山站和Tromso站F2层电离层的极区特征,进一步揭示了极区电离层特征的形成机理。结果表明,中山站和Tromso站虽然地理纬度接近,foF2日变化形成机理不完全相同。由于地磁纬度的差异,极区对流与日侧光致电离的相互作用造成了两站日侧电离层的不同变化形态,中山站foF2日变化主峰出现在磁地方时中午附近,而Tromso站foF2日变化主峰出现在地方时正午附近;两站日侧foF2受太阳辐射流量影响较大,极光沉降粒子电离在太阳活动低年对中山站foF2日变化形态影响显著。 | 朱爱琴 张北辰 黄际英 刘瑞源 | 2008 | 极地研究2008,20,1: | 10 |
| 3 | Averaged NmF2 of cusp-latitude ionosphere in northern hemisphere for solar minimum—Comparison between modeling and ESR during IPY显示文摘Based on the ionosphere observation data obtained by EISCAT Svalbard Radar (ESR) in solar minimum year-2007, we analyzed diurnal variations of F2-peak electron density (NmF2) in four seasons under disturbed and quiet geomagnetic conditions. It indicated that the soft precipitation electron had an evident effect on the NmF2 increase at magnetic noon in spring, summer and autumn and the electron precipitation effects were prominent in winter. The comparison between the IRI-2007 model and the observation exhibited that the IRI (International Reference Ionosphere) model had a better NmF2 prediction when the photoionization was dominant during the polar day, but worse when the electron precipitation was dominant during the polar night. We showed that the electrons in lower energy band decreased when the geomagnetic disturbance went greater, which resulted in the lower NmF2. By analyzing the spectrum of precipitation electron under different geomagnetic conditions, it was found that this phenomenon was induced by the energy flux enhancement of precipitation electron of low energy. | HE Fang ZHANG BeiChen HUANG DeHong | 2012 | Science China(Technological Sciences)2012,55,5: | 8 |

| 5 | Progress in polar upper atmospheric physics research in China显示文摘The Chinese Antarctic Great Wall, Zhongshan, Kunlun and Arctic Yellow River stations have unique geographical locations, well suited to carry out polar upper atmospheric observations. This paper reviews the tremendous history of nearly 30 years of Chinese polar expeditions and major progress in polar upper atmospheric physics research. This includes the polar upper atmospheric physics conjugate observation system at Zhongshan Station in the Antarctic and Yellow River Station in the Arctic, and original research achievements in polar ionospheric fields, aurora and particle precipitation, the polar current system, polar plasma convection, geomagnetic pulsations and space plasma waves, inter-hemispheric comparisons of the space environment, space weather in polar regions, power spectrum of the incoherent scatter radar, ionospheric heating experiments and polar meso- spheric summer echoes, polar ionosphere-magnetosphere numerical simulation and others. Finally, prospects for Chinese polar upper atmospheric physics research are outlined. | LIU Ruiyuan YANG Huigen | 2012 | Advances in Polar Science2012,23,2: | 4 |
| 6 | A conjugate study of the polar ionospheric F2-layer and IRI-2007 at 75 ° magnetic latitude for solar minimum显示文摘Long-duration conjugate observations by the EISCAT Svalbard Radar (ESR) and the ionosonde at Zhongshan station from the International Polar Year (IPY) during solar minimum conditions are analyzed, with respect to variability in the F 2-layer peak parameters. A comparison between International Reference Ionosphere2007 (IRI-2007) and observation data clearly demonstrates good agreement in summer, but greater deviations in winter. The IRI model reproduces the F 2 peak parameters dominated by solar photoionization reasonably well, but it does not address the effect of electron precipitation. Hence, the discrepancies become large in the winter auroral ionosphere. | HE Fang ZHANG BeiChen JoranMoen HUANG DeHong | 2011 | Advances in Polar Science2011,22,3: | 1 |
| 7 | 太阳活动低年南北极电离层F2层观测与国际参考电离层对比研究显示文摘利用2006—2007年EISCAT Svalbard雷达(ESR)和南极中山站DPS-4测高仪的观测数据,对太阳活动低年不同季节的极区电离层F2层临界频率(f_0F2)和峰值高度(h_mF2)进行统计分析,研究其日变化特征,并与国际参考电离层IRI-2007模式比较。结果表明,在太阳活动低年,夏季两站的观测结果与IRI预测符合得较好,冬季预测都与实测结果符合得较差。两者差异表明,IRI-2007模式对极区f_0F2和h_mF2的预测,考虑太阳光致电离的权重较大,对极隙区软电子沉降和极光粒子沉降考虑的权重较小。 | 何昉 张北辰 | 2011 | 极地研究2011,23,3: | 1 |
| 8 | Numerical Simulation of Ionization Enhancement in the Topside Ionosphere of Cusp Foot-Point Region Caused by Low Energy Particle Precipitation显示文摘The Graz Ionospheric Flux Tube Simulations (GIFTS) has been improved.The improved GIFTS model was used to numerically investigate the energy particle precipitation on the distribution of electron density in the ionospheric cusp foot-point region under conditions of large plasma convection during magnetic storm.After including the effects of low energy incident particles,the ionospheric electron densities increase remarkably above altitude of ~250 km,showing a peak at about 350 km.The percent enhance-ments of electron densities increase gradually with altitude,exceeding 60% near the upper boundary of the calculation.The calculated ionospheric F2-peak was remarkably enhanced and lifted up by the incident low energy electrons. | CAI Hongtao MA Shuying G Kirchengast | 2008 | Wuhan University Journal of Natural Sciences2008,13,2: | 0 |
