Local to continental scale coupled fire-atmosphere simulation of large industri...
Baggio, Roberta; Filippi, Jean Baptiste; Truchot, Benjamin; Couto, FlavioThis paper presents an approach to model the multiscale smoke dispersion following industrial fires, based on the atmospheric code Meso-NH coupled with the ForeFire surface fire code. Meso-NH can solve explicitly micro to meso-scale meteorology, while ForeFire allows for an efficient parametrization of the injected heat and vapour fluxes. The combination of these two models allows for a straightforward implemen...
Modelling pyro-convective clouds using the MesoNH and ForeFire models
Couto, Flavio; Filippi, Jean Baptiste; Baggio, Roberta; Salgado, RuiExtreme wildfires are frequently associated with strong convective processes due the heat and moisture released by the combustion. Such a fire-atmosphere coupling environment lead the formation of convective clouds, also referred as PyroCumulus (PyroCu) or PryroCumulonimbus (PyroCb) clouds. In 2017, an extreme fire season affected Portugal. The present study aims to investigate how a wildfire can influence the ...
Modelling pyro-convective activity in Pedrógão Grande mega fire
Couto, Flavio; Filippi, Jean Baptiste; Baggio, Roberta; Salgado, RuiThe development of PyroCumulonimbus (PyroCb) clouds during mega fire events has high impact in the evolution of the fire fronts and have been observed more frequently in the last years. In 2017, Portugal was affected by several episodes of extreme wildfires with associated cloud systems. The present study aims to investigate the development of pyro-convective activity during the Pedrógão Grande episode. The stu...
