International Symposium on Earth-Science Challenges (ISEC) 2013


2008 年にオクラホマ大学大気地理学部と京都大学防災研究所と京都大学生存圏研究所の 3 者間で、大気科学の研究教育推進に関する協定が締結されている。この協定に基づき第 3 回目の国際シンポジウムを開催する。過去 2 回のシンポジウムでは、気象および気候に関する地球科学の挑戦をテーマとして実施されている。その後、京都大学では 2012 年度から気候変動リスク情報創生プログラム課題「課題対応型の精密な影響評価」を防災研主導で進めている中、オクラホマ大学でも気候研究の大御所である Dr. B Moore を新たに大気地理学科の学部長に迎え、さらに副学長に任命して、気象学のみならず気候学にその版図を拡張している。加えて、フェーズドアレイレーダーなど次世代のレーダー技術に関して、日米が世界の先駆を進んでいる。このような状況をふまえ、本研究集会である第 3 回目の国際シンポジウムでも気象および気候に関する先端的なシンポジウムとして、サイエンスからアプリケーションに至る幅広いスペクトラムの議論を展開することを目的とした。


本研究集会では、口頭発表 53 件、ポスター発表 21 件が行われ、100 名を超える多くの参加者を迎えて開催することができた。研究集会では、リモートセンシングを用いた最新の観測技術とその気象観測への応用、ハイインパクト現象に対する解明と予測、防災に資する極端現象と気候変化の解析、という 3 つの大きなテーマを掲げ、加えて、シンポジウムのタイトルである地球科学の挑戦と将来というスペシャルセッションを設け、活発な議論が行われた。また、本研究集会は京都大学とオクラホマ大学の交流の意味を持っており、前回のシンポジウムからおよそ 2 年の歳月を経て、いずれの分野においても、京都大学・オクラホマ大学お互いに目覚ましい進歩を遂げているものと認識することができた。また、若手研究者同士の交流のイベントを行い、近年盛んになりつつある両大学間の人材交流を加速するものと期待できる。2 年後にはオクラホマ大学にて第 4 回目のシンポジウムを開催することの合意も得ることができた。
