发生在森林冠层下的低强度野火会导致特别不利的当地空气质量状况。在这些火灾事件中，环境和火灾引起的湍流环流在烟雾的运输和扩散中起着重要作用。最近对低强度野火期间火-大气相互作用的现场测量为火灾引起的湍流结构以及森林植被如何影响烟雾的水平和垂直扩散提供了新的见解。在本文中，我们总结了在发生在新泽西松树荒地的两次低强度野火事件中所做的关键湍流观测。
Low‐intensity wildland fires occurring beneath forest canopies can result in particularly adverse local air‐quality conditions. Ambient and fire‐induced turbulent circulations play a substantial role in the transport and dispersion of smoke during these fire events. Recent in situ measurements of fire–atmosphere interactions during low‐intensity wildland fires have provided new insight into the structure of fire‐induced turbulence regimes and how forest overstory vegetation can affect the horizontal and vertical dispersion of smoke. In this paper, we provide a summary of the key turbulence observations made during two low‐intensity wildland fire events that occurred in the New Jersey Pine Barrens.
