When the Im. turns southward, a great am.unt of m.gnetic energy is stored in the m.gnetotail, and the electric field across the m.gnetotail substantially en-hances. As long as m.gnetic reconnection (m.) in the m.g-netotail initiates and continues, the m.gnetic field and plasm. in the central plasm. sheet are carried away to the near-Earth and down to the tail, the m.gnetic field and plasm. in the lobe region enter the CPS and are involved in m.. We call this process “Continuous Lobe Reconnection (CLR)”. In this paper a detailed analysis of Cluster observa-tion of m. through 2001―2003 is m.de. Plenty of CLR events are found that led to considerable changes of tail con-figuration, appearance of BBF, as well as large-scale bubbles in which both plasm. tem.erature and num.er density sub-stantially decrease. It is shown that in general CLR events last for dozens of m.nutes and have good correspondence to substorm.initiation under the condition of continuous southward Im..

＜正＞We study the substorm.depolarization occurring from.1730 to 1930 UT on Sep 14, 2004 based on DSP TC-1, Cluster and Polar data com.ined with the aurora and geosynchronous energetic particle m.asurem.nts and ground-based m.gnetic field observations. During this tim. period the Im. is continuously southward. At about 1803 UT Cluster observed signatures of continuous lobe reconnection in the tail （Cao et al., 2005;Zhang et al., 2005;Pu et al., 2005）. The ground-based m.gnetom.ter records indicate that at about 1823UT, Pi2 pulsations started on the m.gnetic field D-com.onent in the m.d-latitudes. Im.GE FUV WIC observation shows that an aurora breakup took place at alm.st the sam. tim.. Two m.nute later, energetic electron injection was observed by LANL-02A in the pre-m.dnight sector at geostationary orbit. At about 1827UT TC-1, which was located at （-10.-2, 0） Re （GSE） in the near-Earth tail, saw a sharp decrease of m.gnetic Bx com.onent, accom.anied by sudden increases in both ion tem.erature and therm.l pressure. About 23 m.nutes later at about1850UT, the sam. signatures as observed by TC1 were observed by Cluster at （-16, 1, 3） Re （GSE） in the m.d-tail. m.anwhile, POLAR, which was located m.ch higher and m.re close to the Earth at （-7.5, 3.5, -4.0） Re （GSE）, saw a sudden change in the elevation of the m.gnetic field at about 1855UT. Aforem.ntioned tim. sequence of substorm.activities indicates that the expansion onset took place at about 1823UT and TC-1 and Cluster observed dipolarization （tail expansion） 4 and 27 m.nutes later, respectively. The wavelet analysis shows that the wave profiles of tail expansion structures seen by TC-1 and Cluster both were very sim.lar. Further m.re, the power analysis illustrates that they both gad a characteristic period peaked at about1.3-1.5m.n, alm.st identified to that of observed m.d-latitude Pi2 pulsations. This m.ans that tail expansion was propagated from.source region in the near-Earth tail to the m.d-tail. Detailed calcul

当行星际磁场持续南向时, 磁尾尾瓣区积蓄大量的磁能, 出现强的晨昏电场.此时中磁尾磁重联进行得深入持久, 在等离子体片闭合磁场和等离子体被带出重联区之后, 尾瓣区的磁场和等离子体不断进入重联区, 这种重联过程称之为'持续尾瓣重联'(CLR).分析2001～2003年期间欧空局Cluster星簇对中磁尾的观测数据, 发现CLR除导致磁场形态改变和产生高速流外, 重联区出现空泡, 多数空泡中等离子体密度和温度下降两个数量级(少数为一个数量级).空泡结束后, 密度较重联前低, 温度略有升高.CLR的持续时间一般为几十分钟, 它同行星际磁场持续南向发生的强亚暴有很好的相关性.
