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.

这项研究代表了通过从综合现场计划中获得新的观察结果并将这些观察结果融入教育和社区外展，以促进对野火 - 大气动力学的理解。该项目的关键目标是：1）更好地理解负责野火 - 大气相互作用的物理机制，以及这些过程如何影响火行为； 2）通过开发创新的消防科学和消防安全外展和教育计划来提高学生对消防天气科学的理解。该研究旨在确定负责影响火灾行为的大气相互作用的过程。该研究方法是基于执行一个激烈的测量程序，该计划将精心计划的实验与快速部署野火监测（RADFIRE）结合在一起，使用新的NSF资助的CSU-MAP，移动大气分析系统。观察结果将与与耦合的WRF火灾模型一起进行的数值模拟进行研究：1）火引起的风的动力学及其对火行为的影响； 2）火羽和近地表环境的热力学结构。该项目的教育部分计划在消防天气研究中建立一项将圣何塞州立大学和社区联系起来的消防天气研究计划。该组成部分将将火灾天气内容纳入通识教育课程，通过教师培训研讨会改善6年级的科学学习，并通过提供一项新颖的现代消防安全教育计划来发展生活在火灾危险区的学生之间的火灾危险意识。组件概念是：1）将火灾天气内容整合到大学课程中； 2）K-12教师培训研讨会，称为野火天气； 3）红色范围：针对荒野城市界面中的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观察到的关键野火大气特性来改变野火研究。这将提供第一个综合数据集，以验证耦合的大气火灾建模系统。对极端火引起的风和李子热力学结构的新观察将导致对野火动态的知识和理解的重大进展。更广泛的影响。这项工作的更广泛影响包括：1。通过开发新的教师培训模块和一项针对火灾危险意识的新型中学计划，开发了教育活动，以提高学生对火灾天气流程的理解，并使用危险信号作为火灾天气道具2。对关键的射击大气过程的更深入了解极端射击行为。3。通过开发更好的预测工具，增加了消防员和公共安全。4。基于Web的数据门户网站为建模社区的长期访问提供了数据集。
