This invention discloses an integrated prediction method and system for fire spread coupled with smoke and meteorological feedback. The method first estimates forest fire emission parameters in real time based on satellite remote sensing data and converts them into spatiotemporal dynamic emission fluxes identifiable by the numerical weather chemistry (WRF-Chem) model. Grid interpolation is then used to match the WRF-Chem meteorological and chemical grid. Secondly, based on WRF-Chem simulations, the bidirectional coupling process between smoke aerosols and the meteorological field is simulated to generate a dynamic meteorological field incorporating smoke radiation feedback. Finally, the dynamic meteorological field is input into the weather-wildfire coupled simulation and the WRF-Fire weather research and forecasting model to simulate the feedback effect of smoke on fire spread. This invention reveals for the first time an aerosol-dominated positive feedback chain: fire emissions, through the synergistic effect of thermodynamic heating and radiative forcing, provide scientific support for disaster prevention decision-making and improve emergency response efficiency.
