This paper advances the general structure of the forming mechanism of firestorm in the forest through analysis on forming and developing process of the forest fire from the angle of combustion and gas dynamics under the boundary conditions given. It maintains that a great forest fire would produce a large quantity of combustible gases on account of combustion in the condition of insufficient oxygen. These gases would bum again and so form the firestorm. The general features of the firestorm and its disastrous consequences are showed clearly. The theory is verified with the exterior characteristics displayed by the firestorm on a macroscopic scale with concrete cases. The paper, finally, proposes the controlling countermeasures.
