研究人员警告说,由于潮湿和风暴停滞,气候变化可能会增加意大利Emilia-Romagna的洪涝风险。
Climate change may increase flood risks in Italy’s Emilia-Romagna due to trapped moisture and stalled storms, researchers warn.
一项新的研究将意大利的Emilia-Romagna地区反复发生的极端洪水与“cul-de-sac”效应联系起来,在“cul-de-sac”效应中,山脉吸收来自亚得里亚海的湿度,加上固定气旋造成的长期降雨量。
A new study links repeated extreme floods in Italy’s Emilia-Romagna region to a “cul-de-sac” effect, where mountain ranges trap moisture from the Adriatic Sea, combined with prolonged rainfall from stationary cyclones.
这一现象被确定为2023年和2024年造成17人死亡和数十亿破坏的洪灾的一个关键因素,由于气候变化,这种现象可能变得更加普遍。
The phenomenon, identified as a key factor in 2023 and 2024 floods that killed 17 and caused billions in damage, may become more common due to climate change.
研究人员警告具有可比地形的类似地中海地区面临更大的洪水风险。
Researchers warn similar Mediterranean areas with comparable topography face heightened flood risks.
它们提出了新的“元密度持久性”衡量标准,以改善预警系统和制订季节性洪水预报,敦促加强备灾和规划工作。
They propose a new “cyclone density persistence” metric to improve early warning systems and develop seasonal-scale flood forecasts, urging better preparedness and planning.
