基于WRF-Fire的大气-林火耦合模拟

Coupled atmosphere-wildland fire modeling with WRF-Fire

Jan Mandel, Jonathan D. Beezley, Adam K. Kochanski

摘要:

我们描述了WRF-Fire的物理模型,数值算法和软件结构。WRF-Fire包括一个火灾蔓延模型,由水平集方法实现,再加上天气研究和预报模型。在每一个时间步,火模型输入的表面风,这驱动了火灾,并输出热通量从火灾到大气中,这反过来又影响大气。水平集方法允许燃烧区域的子网格表示和各种点火模式的灵活实施。WRF-Fire是WRF的一部分,它使用WRF并行基础设施进行并行计算。

英文摘要:

We describe the physical model, numerical algorithms, and software structure of WRF-Fire. WRF-Fire consists of a fire-spread model, implemented by the level-set method, coupled with the Weather Research and Forecasting model. In every time step, the fire model inputs the surface wind, which drives the fire, and outputs the heat flux from the fire into the atmosphere, which in turn influences the atmosphere. The level-set method allows submesh representation of the burning region and flexible implementation of various ignition modes. WRF-Fire is distributed as a part of WRF and it uses the WRF parallel infrastructure for parallel computing.
