• Keywords: 全球雲解像モデル / 大気海洋結合モデル / 気候シミュレーション

Outline of Research at the Start

全球非静力学モデルを用い、全球雲解像気候実験の先駆けとなる10kmメッシュ以下での10年積分という世界初の気候実験を実施する。再現性の調査、既存モデルとの比較、感度実験、および大気海洋結合テスト実験により全球雲解像気候モデル実現に向けた課題を世界に先駆けて特定し、その解決に挑戦する。これにより、気候システムにおける雲・気候の相互作用の理解と予測に革新をもたらす全球雲解像気候モデルを獲得する。

Outline of Annual Research Achievements

DNA（Deep Numerical Analysis）気候学の開拓を目指し、全球非静力学モデルNICAMおよび大気海洋結合モデルNICOCOを信頼できる次世代全球気候モデルとして確立するため、本年度はスーパーコンピュータ「富岳」において、前年度までに決定した全球雲解像気候実験の標準設定を用いて3.5kmメッシュのNICAMを用いた10年実験を実施した。結果を解析した結果、熱帯季節内振動の活発化頻度や伝搬、ならびにその影響を強く受けるスーパー台風（ここでは生涯最低中心気圧が920hPa以下）の経路や構造の特徴がよく再現されていること、梅雨前線の季節進行など日本を含む中緯度域の気候場の再現性が向上していることが明らかになった。並行して大気14km、海洋0.25度メッシュのNICOCOを用いた大気海洋結合実験を3種類のモデル設定で5年以上実施し、最新のNICAM標準設定を用いることで海水面温度のドリフトが低減すること、サンプル数が少ない限界はあるもののENSOに似た振動が見られことが明らかになり、NICOCOの有望性を示すことができた。この結果を受けて、大気3.5km、海洋0.1度メッシュのNICOCOを用いた大気海洋結合実験を開始した。また、熱帯における大気海洋結合を評価する新しい手法として、海水面温度と鉛直積算水蒸気量の季節内成分から定義される2次元ダイアグラムを提案した。この評価手法を再解析データおよびNICOCO実験データに適用した結果、インドおよび太平洋暖水域では両者の間の位相関係は整合的であったが、中央太平洋域では逆向きの関係が得られた。このような関係は、大気擾乱が海水面温度へ与える影響の差異によって説明可能であり、今後のモデル改良に対する指針を与えることが期待できる。
