Observation of a Sharp Negative Dipolarization Front in the Reconnection Outflow Region
Zhou, Meng; Deng, Xiao-Hua; Pang, Ye +1 more
A sharp dipolarization front (DF) has recently been detected in the Earth's magnetotail and is associated with complex kinetic effects. We present one event where a tailward propagating negative DF (with Bz decreasing sharply to negative value) was observed near a reconnection region. The thickness of the negative DF is comparable with …
Field-Aligned Currents at the PSBL on 17 August 2001 Storm: Relationships with solar Wind Conditions
Liu, Zhen-Xing; Shi, Jian-Kui; Cheng, Zheng-Wei +2 more
Using magnetic field and plasma data acquired with Cluster spacecrafts, we investigate the relationship between the field-aligned currents (FACs) at the plasma sheet boundary layer (PSBL) and solar wind dynamic pressure, as well as the interplanetary magnetic field (IMF) By on 17 August 2001 storm. Our studies reveal that FAC density at…
Clarification on Polarity of Bipolar Electric Field Solitary Structures in Space Plasmas with Satellite Observation
Liu, Zhen-Xing; Shi, Jian-Kui; Qureshi, M. N. S. +1 more
The bipolar electric field solitary (EFS) structures observed frequently in space plasmas by satellites have two different polarities, first positive electric field peak then negative (i.e., positive/negative) and first negative then positive peak (i.e., negative/positive). We provide the physical explanation on the polarity of observed bipolar EF…
Model of the Crustal Magnetic Field in the Martian Aurora Zone
Tong, Dong-Sheng; Chen, Chu-Xin
It is well known that aurorae are prominent on planets with a global magnetic field and occur where open magnetic field lines converge. The UV spectrometer used for investigating the characteristics of the atmosphere of Mars (SPICAM) on board the Mars Express made the first observation of auroral-type emission in the cusp region of the strong crus…
