Jan Mandel, Jonathan D. Beezley, Soham Chakraborty, Janice L. Coen, Craig C. Douglas, Anthony Vodacek, Zhen Wang

摘要:

一个荒地火灾模式的基础上的半经验关系的地面火和锋面后的热量释放的蔓延速度耦合的天气研究和预报大气模式(WRF)。火锋的传播是通过水平集方法实现的。数据同化的变形集合卡尔曼滤波器,它提供了幅度以及位置校正。火灾的热图像将提供观测结果,并将与来自模型状态的合成图像进行比较。

英文摘要:

A wildland fire model based on semi-empirical relations for the spread rate of a surface fire and post-frontal heat release is coupled with the Weather Research and Forecasting atmospheric model (WRF). The propagation of the fire front is implemented by a level set method. Data is assimilated by a morphing ensemble Kalman filter, which provides amplitude as well as position corrections. Thermal images of a fire will provide the observations and will be compared to a synthetic image from the model state.
