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

这个RAPID项目是一项雄心勃勃的努力，旨在通过收集现场观察结果来帮助指导WRF-SFIRE对事件的建模，从而促进我们对2017年葡萄酒之乡火灾期间暗黑破坏神风动力学及其对极端火灾行为的影响的理解。该项目的主要成果是：（1）增强的气候分析，包括葡萄酒之乡火灾附近的地点，并包括气候分析的压力梯度标准，（2）事件演变的天气和卫星分析，以确定对火灾蔓延的大规模强迫，（3）导致科菲公园附近破坏的塔布斯火灾事件的高分辨率WRF建模，（4）WRF-SFIRE模拟，包括重建塔布斯火灾的火灾前沿位置，（5）火焰输送模型的测试，以模拟极端风力驱动的野火中的暴雨，以及（6）邀请主要利益相关者在SJSU举办了为期一天的暗黑破坏神风研讨会。智力优势：RAPID项目将通过开发第一个暗黑破坏神风事件的气候学并将天气模式与气候风特征的变化。这将有助于更好地了解如何在关键的火灾天气条件下预测这些风。此外，重建摧毁了近5700所房屋的塔布斯大火的相关火灾行为模式，将有助于更好地了解近地表的空气输送如何导致火灾快速蔓延。更广泛的影响：RAPID项目的预期更广泛的影响包括：- 更好地了解与暗黑破坏神风事件相关的关键火灾天气条件和火灾行为，以及-为利益相关者/火灾管理人员举办Diablo风力研讨会，以传播为期一年的研究结果。

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.
