FireFlux II实验于2013年1月30日在德克萨斯州东南部的一个高草草原上进行，该实验是在区域燃烧禁令和高火灾危险条件下进行的。实验的目的是更好地了解火灾蔓延的微气象方面。实验设计的指导下使用的火灾-大气耦合模型，预测火灾蔓延提前。初步结果表明，点火后，表面压力扰动形成和加强的火锋和羽流的发展，导致风速增加，在火锋。火灾引起的风平流热燃烧气体向前和顺风的火锋，导致空气加速通过火焰前锋。总的来说，实验收集了大量的微气象，空气化学和火灾行为数据，可以提供一个全面的数据集，用于评估和测试耦合火灾-大气模型系统。
The FireFlux II experiment was conducted in a tall grass prairie located in south-east Texas on 30 January 2013 under a regional burn ban and high fire danger conditions. The goal of the experiment was to better understand micrometeorological aspects of fire spread. The experimental design was guided by the use of a coupled fire-atmosphere model that predicted the fire spread in advance. Preliminary results show that after ignition, a surface pressure perturbation formed and strengthened as the fire front and plume developed, causing an increase in wind velocity at the fire front. The fire-induced winds advected hot combustion gases forward and downwind of the fire front that resulted in acceleration of air through the flame front. Overall, the experiment collected a large set of micrometeorological, air chemistry and fire behaviour data that may provide a comprehensive dataset for evaluating and testing coupled fire-atmosphere model systems.
