The Role of Atmospheric Circulation in Favouring Forest Fires in the Extreme So...
Purificação, Carolina; Henkes, Alice; Kartsios, Stergios; Couto, Flavio TiagoThe study explores two forest fires in extreme southern Portugal aiming to increase the knowledge of how atmospheric circulation influenced the fire dynamics in each event. The meteorological conditions were simulated by the Meso-NH full-physics non-hydrostatic limited-area research model. The two numerical simulations were performed using a two-way nested domain configuration with horizontal resolutions of 250...
A Quick Look at the Atmospheric Circulation Leading to Extreme Weather Phenomen...
Couto, Flavio Tiago; Kartsios, Stergios; Lacroix, Matthieu; Andrade, Hugo NunesThe study delves into the primary large-scale atmospheric features contributing to extreme weather events across Europe during early September 2023. The period was examined using a dataset composed by the European Centre for Medium-Range Weather Forecasts (ECMWF) analysis and satellite imagery. In early September 2023, an omega blocking pattern led to the development of a low-pressure system over the Iberian Pe...
Application of atmospheric modelling to understand wildfires environment in Sou...
Purificação, Carolina; Henkes, Alice; Kartsios, Stergios; Couto, Flavio TiagoMeteorological conditions are an important factor contributing to extreme fire environment. Southern Portugal has some susceptible regions to fire with at least 4 mega fires occurring in the last two decades. Aiming to investigate in detail the atmospheric environment of large fires, several numerical simulations were performed using the Meso-NH non-hydrostatic research model. Some simulations were configured u...
Meteorological environments leading to two large fires in Southern Portugal
Purificação, Carolina; Campos, Cátia; Henkes, Alice; Kartsios, Stergios; Couto, Flavio TiagoThe study is a step forward in the characterization of meteorological environments that favour the evolution of large and extreme fires in Southern Portugal. The region has some fire-prone areas which are recognized by the mega fires occurred in 2003, 2005, and 2018. Two numerical simulations were performed using the Meso-NH non-hydrostatic research model and used to investigate in detail the atmospheric enviro...
Operational platform for metocean forecasts in Thermaikos Gulf (Aegean Sea, Gre...
Androulidakis, Yannis; Makris, Christos; Kolovoyiannis, Vassilis; Kombiadou, Katerina; Krestenitis, Yannis; Kartsios, Stergios; Pytharoulis, IoannisThermaikos Gulf, located in the northeastern Mediterranean Sea, faces significant anthropogenic pressures and natural hazards, requiring reliable metocean forecasts for weather, ocean circulation, sea levels, waves, and hazard predictions, including pollutant transport, coastal floods, and freshwater discharges. The Wave4Us operational platform addresses these needs by providing high-resolution and specialised ...
INTERCOMPARAÇÃO DE SIMULAÇÕES NUMÉRICAS COM MODELOS ATMOSFÉRICOS ACOPLADOS A MO...
Couto, Flavio; Salgado, Rui; Filippi, Jean-Baptiste; Baggio, Roberta; Kartsios, Stergios; Cardoso, Rita; Soares, Pedro; Campos, CátiaA propagação do fogo associada à atividade piro-convectiva extrema é atualmente altamente imprevisível e difícil de combater. Este relatório apresenta os principais resultados de simulações realizadas a partir do acoplamento entre modelos de resolução de nuvens e modelos de propagação de fogo, nomeadamente MesoNH/ForeFire, WRF/FIRE e WRF/SFIRE. Os códigos acoplados foram utilizados no estudo dos mega incêndios ...
