O fenómeno da piro-convecção e condições de larga escala que favorecem o desenvolvimento de mega-incêndios

Abstract

In this study, two numerical simulations were made using the MesoNH atmospheric model: a simulation coupled with the fire propagation model, ForeFire, with 3 nested domains (2000m, 400m and 80m of horizontal resolution) and a noncoupled simulation, with a single domain of 15km horizontal resolution. From the first simulation, significant pyroconvective activity was confirmed from the moment that some type of hydrometeor was simulated inside the smoke plume, i.e., the development of a PyroCu cloud. In the large-scale context, the approach of the hurricane Ophelia contributed to the mega-fires and strong pyro-convective activity.
