The research represents an effort to advance the understanding of wildfire-atmosphere dynamics by obtaining new observations from a comprehensive field program and integrating these observations into education and community outreach. The key objectives of the project are: 1) to develop a better understanding of the physical mechanisms responsible for wildfire-atmosphere interactions and how these processes influence fire behavior; 2) to improve student understanding of fire weather science through the development of an innovative fire science and fire safety outreach and education program.The research seeks to identify the processes responsible for fire-atmosphere interactions that affect fire behavior. The research methods are based on executing an intensive measurement program that incorporates carefully planned experiments with rapid-deploy wildfire monitoring (RaDFIRE) using the newly NSF funded CSU-MAPS, mobile atmospheric profiling system. Observations will be integrated with numerical simulations made with the coupled WRF-Fire model to investigate: 1) the dynamics of fire-induced winds and their impact on fire behavior; 2) the thermodynamic structure of fire plumes and the near-surface environment.The education component of the project plans to build a university program in fire weather research that links San José State University and the community. This component will integrate fire weather content into general education courses, improve 6th grade science learning through a teacher training workshop, and develop fire danger awareness among students living in fire danger zones by providing a novel and modern fire safety education program. The component concepts are: 1) integration of Fire Weather content into university courses; 2) K-12 Teacher Training workshop called Weather of Wildfires; 3) Red-Flag Days: A community outreach program for middle schools in the Wildland-Urban Interface aimed at providing fire safety education.Intellectual merit. The work will potentially transform wildfire research by measuring critical wildfire-atmosphere properties that have rarely been observed. This will provide the first comprehensive data set for the validation of coupled atmosphere-fire modeling systems. New observations of extreme fire-induced winds and plume thermodynamic structure will lead to major advances in knowledge and understanding of wildfire dynamics. Broader impacts. The broader impacts of this work include:1. Educational activities are developed to improve student understanding of fire weather processes by developing new teacher training modules and a novel middle-school program aimed at fire danger awareness with the use of red flags as fire weather props.2. Greater understanding of critical fire-atmosphere processes responsible for extreme fire behavior.3. Increased firefighter and public safety from the development of better prediction tools.4. Web-based data portal developed to provide modeling community long-term access to datasets.

该研究代表了通过从综合实地计划中获得新的观察结果并将这些观察结果纳入教育和社区外展中来增进对野火-大气动态的理解的努力。该项目的主要目标是：1）更好地了解野火-大气动态。负责野火与大气相互作用的物理机制以及这些过程如何影响火灾行为；2）通过制定创新的火灾科学和消防安全推广和教育计划，提高学生对火灾天气科学的理解。该研究旨在确定负责的过程；对于影响火与气氛相互作用的研究方法基于执行密集的测量计划，该计划将使用新资助的 CSU-MAPS、移动大气剖面系统和快速部署野火监测 (RaDFIRE) 与精心策划的实验相结合。 WRF-Fire 模型可研究：1) 火灾引起的风的动力学及其对火灾行为的影响；2) 火羽流和近地表环境的热力学结构。项目计划的教育部分；建立一个将圣何塞州立大学和社区联系起来的火灾天气研究大学项目。该部分将把火灾天气内容纳入普通教育课程，通过教师培训研讨会改善六年级的科学学习，并培养学生的火灾危险意识。通过提供新颖且现代的消防安全教育计划，其组成部分包括：1) 将火灾天气内容纳入大学课程；2) 称为“野火天气”的 K-12 教师培训研讨会； ：社区外展计划这项工作可能会通过测量很少被观察到的关键野火-大气特性来改变野火研究，这将为验证野火提供第一个全面的数据集。对极端火灾引起的风和羽流热力学结构的新观察将导致对野火动力学的认识和理解取得重大进展。这项工作的更广泛影响包括：1。提高学生通过开发新的教师培训模块和新颖的中学课程来了解火灾天气过程，旨在利用红旗作为火灾天气道具来提高火灾危险意识。2. 更好地了解导致极端火灾行为的关键火灾气氛过程。 3. 通过开发更好的预测工具来提高消防员和公共安全。4. 开发基于网络的数据门户，为建模界提供对数据集的长期访问。
