Research Abstract

本研究の目的は超高層大気中を流れる大規模電流系の短期的・長期的変動を調査し、太陽地球系における太陽圏-磁気圏-電離圏-大気圏結合過程を定量的に理解することである。目的達成のため、赤道ジェット電流を含む電離圏グローバルSq電流系が導出できるリアルタイム観測データを取得するため、既存のMAGDAS、電離圏電場観測レーダー観測点の再整備・強化、観測データに基づく太陽地球系における太陽圏-磁気圏-電離圏-大気圏結合過程を定量的に理解するための解析研究の実施、得られた研究成果を公開した。
平成24年度は事情により繰越申請を行い、24,25年度で研究を遂行した。海外共同研究者の協力を得て研究代表者の指示の下、分担者4名と大学院生を含む研究協力者6名が中心となり全球的規模のMAGDASリアルタイムデータ収集及び電離圏レーダー観測網(Yumoto et al., 2006－2008)の追加・再整備を行い、インドネシア、フィリピン、インド、ヤップ島、エクアドル、南アフリカ、カナダ、ブラジル等でMAGDAS磁力計の保守整備と新設並びに篠栗、フィリピンの電離層電場レーダーの保守点検を実施した。
観測で得たデータ解析からグローバルな電離層Sq電流及び赤道ジェット電流系の地域依存性についてアフリカ・アジア・南米域の相互比較の観点から集中的に調査、こうしたグローバルな電離層電流系に対して強い地域性が存在することが確かめられ、大陸毎の気象条件の違いが超高層大気現象にいかに結びつくかという上下結合問題へ発展することが期待される。また、極域と磁気赤道域のグローバルな結合電流系では、午前中に強い電流集中が起こり、午後には相対的に弱くなるという非対称性が発見され、この現象は周期数十秒程度のULF波動から数十分程度のDp2変動現象で共通の特徴であることがわかった。さらに得られた成果を国際会議や国際誌に発表した。
