Extreme Ocean Warming

Updating extreme ocean warming (EOW) events around Japan

• (Top) The area names and the area-averaged SSTs and anomalies

  • Notations “*” and “**” represent EOW events less frequent than once per 20 years and 100 years, respectively

• (Bottom) FAR for EOW events and the corresponding return periods in the preindustrial and present climate conditions

  • RP0=1/Prob(preindustrial) and RP1=1/Prob(present)
  • FAR (Fraction of Attributable Risks)=1–Prob(preindustrial)/Prob(present)
  • Notations “*”, “**”, and “***” represent that the EOW event is accompanied by FAR greater than 0.0, 0.5, and 0.9 significantly at the 95% confidence levels

日本近海の極端海洋昇温イベントのデータ更新

• (上) 海域番号と海域平均した海面水温(SST)および平年差

  • 星印*(**)は20年(100年)に一度以下の極端海洋昇温イベント。

• (下) 極端海洋昇温イベントのFAR(参考)と工業化前・現在の気候での確率年

  • RP0=1/確率(工業化前)とRP1=1/確率(現在)
  • FAR (温暖化の寄与率)=1–確率(工業化前)/確率(現在)
  • 星印* (**, ***)は95％有意にFARが0.0 (0.5, 0.9)を上回る極端海洋昇温イベント
