The Low Latitude Boundary Layer Model

对地球磁层低纬边界层的形成和维持提出了几点非常规的看法。提出了沿LLBL闭合场线向尾部流动的太阳风等离子体对磁尾的维持作用。起源于电离层的场定向离子束被识别为o区电流。在维京卫星数据和MAGSAT数据中寻找区域洋流的证据。为了研究极光弧，将使用声波雷达设备获得改进的场排列电子流和离子流测量结果。计划在3月份与极光成像器一起开展一项活动。提出了极光弧的模型，所获得的数据将允许对该理论模型进行检验。该项目将利用来自各种卫星(MAGSAT、HILAT、DMSP、ISEE3)的观测数据和雷达观测来检验LLBL和极光弧的理论模型。

Several unconventional ideas on the formation and maintenance of the low latitude boundary layer (LLBL) of the terrestrial magnetosphere are proposed. It is proposed that the solar wind plasma flowing tailward on the closed field lines in the LLBL maintains the magnetotail. Field-aligned ion beams of the ionospheric origin are identified as region o currents. The evidence of the region o currents is sought in Viking satellite data and MAGSAT data. For the study of auroral arc, sonderstrom radar facility will be used to obtain improved measurements of field-aligned election and ion flows. A campaign is planned in March 1989 in conjunction with auroral imagers. A model for the auroral arc is proposed and the data obtained will allow the testing of this theoretical model. This project will utilize observational sets of data from various satellites (MAGSAT, Hilat, DMSP, ISEE 3) and radar observations to test the theoretical models of LLBL and auroral arc.
