试用三维地形模式计算茂密林区火险等级

Trying out 3-d topographic model cal culated fire warning class in dense forest region

本文用考虑森林植被的三维地形模式,对1972年4月15日神农架林区森林火灾发生期间的风场、温度场和相对湿度场等进行了模拟,并在此基础上计算森林火险等级。结果表明,采用数值模拟方法可以得到无测站地区的气象要素,为进行森林火险等级预报奠定了基础。

The paper simulated wind,temperatu re and similar humidity field on Apr.151972within occurrence period of forest f ire incident in Shengnongjia forest region by using 3-d topog-raphy model with forest plant cover,and calculated forest fire warning c lass on the above basis.Results show that taking numerical m odeling method could get meteorological elements in the region without observation stations.
