The relationship between ionospheric ion upflow and electrons(thermal electrons and secondary electrons caused by particle precipitations) in/near the dayside cusp region has been investigated. This study was based on new observations with the European Incoherent Scatter(EISCAT) Svalbard radar(ESR), and statistical analysis using ESR database. From these investigations, relationships between ion upflow, electron heating, and ion-acoustic turbulences were quantitatively understood.

本文研究了电离层离子上升流与向阳面尖区及其附近电子（热电子和粒子沉降引起的二次电子）的关系。这项研究是基于欧洲非相干散射（EISCAT）斯瓦尔巴特群岛雷达（ESR）的新观测，并使用ESR数据库进行统计分析。从这些调查中，离子上流，电子加热，和离子声发射之间的关系进行了定量了解。
