Outline of Annual Research Achievements

本研究は、顕著な気候変動をもたらすエルニーニョ南方振動の超高層大気への影響を明らかにすることを目的としている。平成２８年は衛星観測による熱圏風を分析し、その全球分布と季節変化、さらに通信に直接影響する電離圏不規則体の生成との関係を明らかにした。さらに、数値シミュレーションも順調に進展し、結果を分析中である。

Current Status of Research Progress

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

Reason

観測データが予定通り手に入れたので、順調に進むことができた。

Strategy for Future Research Activity

数値シミュレーション結果分析を続き、論文にまとめる

Causes of Carryover

国際学会への参加は、教育業務とスケジュールに合わないため、思った取りに参加できなかった。

Expenditure Plan for Carryover Budget

論文の投稿費や、学会発表に使いたい。
