坚持磁层和电离层为相互耦合整体的学术思想,以极区电离层不均匀体为切入点,系统性地研究了不同条件下极区电离层不均匀体的物理性质及其与磁层动力学过程的关系等,取得了系列进展。主要创新成果如下:(1)首次在地球极地中高层大气中发现了超强能量注入新现象——“太空台风”,揭示了其形成机理,给出了地球空间能量传输的新途径,成果发表Nature
Communications后被《Nature》选为了研究亮点,入选中科院发布的《2022科学发展报告》中2021年中国科研代表性成果20项成果之一;(2)首次完整观测证实了太阳风-磁层能量耦合的理论基石——Dungey循环理论,为近60年日地能量耦合研究方面悬而未决的该科学难题画上了句号,成为了《Science》当期亮点科学论文,入选《基金委资助项目优秀成果选编(六)》是“十二五”地学部25项入选成果之一(空间物理两项成果之一);(3)发现地球粒子上行和逃逸的新源区,指出传统电离层闪烁指数易受对流影响而在高纬不适用并提出改进方法,提升了对地球粒子逃逸和极区通讯、导航、遥感保障的认识。
