Outline of Annual Research Achievements

本研究課題では、太陽、太陽風の擾乱に起因して、地球電磁気圏において生起する様々な電磁気擾乱のうち、宇宙放射線(太陽陽子、放射線帯電子)、電離圏変動、地磁気誘導電流に注目し、それぞれの変動現象の解明と予測を目指した研究を推進している。また、本研究で開発したモデルの成果については、本研究領域の計画班A01を通して、宇宙飛行士の被ばくや、通信障害、測位誤差、地上における誘導電流の評価といった具体的な宇宙天気の影響を評価したものとして、社会に発信していくことを目指している。H28年度の主な成果は以下である。
(1)宇宙放射線サブグループ:基本モデルおよび発展モデル(非線形波動粒子相互作用モデル)の開発を行った。また、2016年12月に、ジオスペース探査衛星「あらせ」が打ち上げられ、放射線帯に関する新しい観測がスタートし、初期データの解析を開始した。
(2)電離圏サブグループ:地球全大気モデルであるGAIAにより、赤道域プラズマバブルの発生予測が可能であること、太陽フレアの影響により夕方側電離圏に東向き電場が発達することを示した。また、プラズマバブルに関するワークショップを開催し、研究成果を国際学術雑誌の特集号に
取りまとめることにした。
(3)地球誘導電流班:国内電力会社の協力を得て、2カ所の変電所で地磁気誘導電流の測定を開始した。日本の高圧送電網(50万ボルト線)を模擬した仮想送電網モデルを開発した。太陽風シミュレーションを用いて中緯度域の地磁気変動を概ね再現することができた。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

3つのサブグループによって、所期の計画に沿って活動を進めるとともに、多数の成果が報道で紹介されるなど多くの成果を得ている。また、国際連携の推進や、国際ワークショップの開催等の活動も活発に行われている。

Strategy for Future Research Activity

実施計画に沿ってモデルの開発、また観測による検証を実施していく。特に地磁気誘導電流の研究については、電力会社との連携を密に実施していく。また、社会に対して成果を発信していくため、具体的な宇宙天気イベントについての予測も試みる。
