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.

这项研究代表了一项努力，通过从一个全面的实地项目中获得新的观察结果，并将这些观察结果纳入教育和社区宣传，来促进对野火大气动力学的理解。该项目的主要目标是：1）更好地理解野火-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）通过开发创新的火灾科学和消防安全宣传和教育计划，提高学生对火灾天气科学的理解。研究旨在确定负责火灾的过程-影响火灾行为的大气相互作用。研究方法是基于执行一个密集的测量计划，结合精心策划的实验与快速部署野火监测（RaDFIRE）使用新的NSF资助的CSU-MAPS，移动的大气剖面系统。观测结果将与WRF-Fire耦合模式的数值模拟相结合，以研究：1）火灾引起的风的动力学及其对火灾行为的影响; 2）火羽流的热力学结构和近地表环境。该项目的教育部分计划建立一个连接圣何塞州立大学和社区的火灾天气研究大学计划。该组成部分将火灾天气内容整合到通识教育课程中，通过教师培训研讨会提高六年级的科学学习，并通过提供新颖和现代的消防安全教育计划来提高生活在火灾危险区的学生的火灾危险意识。组件概念包括：1）将火灾天气内容整合到大学课程中; 2）K-12教师培训讲习班，称为野火天气; 3）红旗日：一个针对荒地-城市界面中学的社区外展计划，旨在提供消防安全教育。这项工作将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。这将为验证大气-火灾耦合模型系统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野火动力学知识和理解的重大进展。更广泛的影响。这项工作的更广泛的影响包括：1。通过开发新的教师培训模块和一个新颖的中学课程，开发教育活动，以提高学生对火灾天气过程的理解，该课程旨在利用红旗作为火灾天气道具提高火灾危险意识。更好地理解导致极端火灾行为的关键火灾-大气过程。从更好的预测工具的发展增加消防员和公共安全。4.开发基于Web的数据门户，为建模社区提供对数据集的长期访问。
