At peak, the cyclone reached a minimum pressure of around 900 mbar (26.58 inHg), the lowest pressure of an extratropical cyclone since at least the start of the satellite era in 1980. The deepening rate of the cyclone was greater than 93.4% of other extreme cyclones. [2] Research from the Geophysical Research Letters article shows that amount of extreme extratropical cyclones, especially in the Amundsen and Bellingshausen Seas, has significantly increased between 1980 and 2022. Additionally, the southwest Pacific Ocean and the South Atlantic has seen a decrease in extreme cyclones. [2] At least five cyclones in the Southern Ocean have had pressure equal to or less than 914 mbar (27.0 inHg), the same pressure as the Braer Storm. [2] [8]
