Research Abstract

・気象庁長期再解析(JRA-25)デニタ仁基づき,小笠原高気圧の勢力に影響する「シルクロード・パターン」が,アジアジェット上の定常ロスビー波という既知の特性に加え,ジェットから位置エネルギーを効率的に変換して循環偏差を維持し,かつ運動エネルギーの損失が最少となるよう地理的位相が決まる力学モードとしての特性を有することを見出した.
・秋季の北極海の海氷変動が日本を含むユーラシア各地に異常寒波をもたらす可能性をJRA-25と数値実験で確認した.
・JRA-25データの解析から,2007年3月の成層圏突然昇温現象の直後に,上方伝播していた惑星波が成層圏で反射され,対流圏へ下方伝播したことを見出した.
・最近の北半球冬季成層圏循環の予測可能性を調べ,平均して約10日先から予測可能であるが,それは5〜20日の間で大きく変動することを示した.
・JRA-25データに基づき,真冬の北極振動の地上気圧偏差の前兆として晩秋にシベリア上空に現れる対流圏波動を特定し,それが惑星規模波動の構造を変調させることで成層圏極渦強度に影響することを見出した.
・中緯度海洋フロント域における大気から海洋の影響を,理想化数値実験並びに現場観測と船舶観測資料から示し,大気再解析データセットの有用性を検証した.
・大気大循環モデルによる成長モード育成法案験と再解析実験を比較し,大気循環の解析値に含まれる誤差の分布の特徴を示した.
・TRMM衛星から推定した潜熱解放量データとJRA-25データとを用い,熱帯の大規模下降流域では高6海面水温で毛深い積雲対流が抑制され浅い加熱が卓越することを見出した
・JRA-25長期再解析に基づき,全球降水量の変動が熱帯低気圧活動に大きく影響され,また北西太平洋では長期的なトレンドはないが,北大西洋では増加,北東太平洋で減少の傾向が見出された.
