多点点点燃的野火在加利福尼亚造成最大的破坏,一个新的模型旨在预测这些破坏。 Rare multi-ignition wildfires cause most damage in California, and a new model aims to predict them.

《科学进步》的一项新研究表明,多点点点燃的野火虽然少见,却造成不成比例的破坏——只有7%的加利福尼亚火灾占被烧毁土地的31%。 A new study in Science Advances reveals that multi-ignition wildfires, though rare, cause a disproportionate amount of damage—just 7% of California’s fires accounted for 31% of burned land. 使用E3SM模型,研究人员发现这些火灾合在一起,传播得更快,并触发了危险的高温热气流暴,产生闪电,引发新的火灾。 Using the E3SM model, researchers found these fires merge, spread faster, and trigger dangerous pyrocumulonimbus storms that generate lightning, sparking new fires. 模型框架将火灾行为与每公里的大气状况联系起来,目的是预测此类事件,协助消防员的安全和基础设施规划。 The modeling framework, which links fire behavior to atmospheric conditions at a kilometer scale, aims to predict such events, aiding firefighter safety and infrastructure planning. 2026年美国航天局实地行动的未来数据将完善该模型。 Future data from a 2026 NASA field campaign will refine the model.
