| 摘 要： | 研究林火行为同空气运动的相互作用对扑灭林火十分重要。文章建立了强温度扰动下空气运动的二维非线性准弹性模式，模拟了林火在静稳大气、环境风垂直切变和地面风促进延烧等三种条件下引起的空气运动场、温度场的结构和演变过程，得到了合理的结果。文章还分析比较了这三种条件下空气运动和热量输送的差异以及地面回流风的特点。

| Abstract: | A Study of the interaction between the bbaviour of forest fire and associatd airmotion is very important for extinguishing the fire.A two-dimensional non-linearquasielastic model of air motion associated with severe temperature disturbance wasdeveloped.The structure and evolution of air motion and temperature fields associatedwith forest fire under three kinds of conditions were simulated,which are calmatmosphere,vertically sheared wind and spreading fire with surface wind.The resultswere reasonable. Differences of air motion and heat transfer under these conditions wereinvestigated and the surface reverse wind was analyzed. |
