RAPID: The Diablo Wind and Extreme Fire Behavior during the 2017 Wine Country Fires

这个快速项目代表着一项雄心勃勃的努力，通过收集现场观测来帮助指导WRF-Sfire对事件的建模，来促进我们对暗黑破坏神风力动力学及其对2017年葡萄酒之乡火灾期间极端火灾行为的影响的理解。该项目的主要成果是：(1)增强的气候学分析，包括葡萄酒产区火灾附近的地点，并包括气候学分析的气压梯度标准；(2)事件演变的天气和卫星分析，以确定对火灾传播的大范围强迫；(3)导致Coffey Park社区被摧毁的Tubbs Fire事件的高分辨率WRF模拟；(4)WRF-Sfire模拟，包括重建Tubbs Fire的火焰前沿位置；(5)火焰传输模拟测试，以模拟极端风致野火中的余烬阵雨，以及(6)在上海州立大学与主要利益攸关方一起开展为期一天的暗黑破坏神风研讨会。智力上的好处：该快速项目将潜在地改变野火研究，开发出第一个暗黑暗黑风事件的气候学，并将天气模式与气候学风特征的变化联系起来。这将使人们更好地理解如何在关键的火灾天气条件下预测这些风。此外，重建摧毁近5700所房屋的Tubbs大火的相关火灾行为模式将有助于更好地了解近地表余烬运输如何导致火灾快速蔓延。广泛影响：快速项目的预期更广泛影响包括：-更好地了解关键火灾天气条件和与Diablo风事件相关的火灾行为，-改进气候学和对事件频率的了解，以及-为利益相关者/消防经理开发一个Diablo风研讨会，以传播为期1年的研究结果。

This RAPID project represents an ambitious effort to advance our understanding of Diablo wind dynamics and their impact on extreme fire behavior during the 2017 wine country fires by collecting field observations to help guide WRF-SFIRE modeling of the events. The key outcomes from this project are:(1) an enhanced climatological analysis to include sites near the wine country fires and including a pressure gradient criteria to climatological analyses,(2) a synoptic and satellite analysis of event evolution to determine large-scale forcing on fire spread,(3) high-resolution WRF modeling of Tubbs Fire event that led to the destruction of the Coffey Park neighborhood,(4) WRF-SFIRE simulations including a reconstruction of fire-front positions for the Tubbs Fire,(5) a test of firebrand transport modeling to emulate ember showers in extreme wind-driven wildfires, and(6) the development of a 1-day Diablo Wind Workshop conducted at SJSU with major stakeholders invited.Intellectual Merit:The RAPID project will potentially transform wildfire research by developing a first climatology of Diablo wind events and linking synoptic patterns to variations in the climatological wind characteristics. This will lead to a better understanding of how these winds can be forecasted during critical fire weather conditions. In addition, a reconstruction of the associated fire behavior patterns from the Tubbs Fire that destroyed nearly 5700 homes will lead to better understanding of how near-surface ember transport can result in rapid fire spread.Broader Impacts:The expected broader impacts of the RAPID project include:- a greater understanding of critical fire weather conditions and fire behavior associated with Diablo wind events,- improved climatology and understanding of event frequency, and- the development of a Diablo wind workshop for stakeholders / fire managers to disseminate results from the 1-year study.
