How a mesoscale cyclonic vortex over Sahara leads to a dust outbreak in South-w...
Couto, Flavio; Cardoso, Eduardo; Costa, Maria João; Salgado, Rui; Guerrero Rascado, Juan Luis; Salgueiro, VandaThe study focused on an exceptional desert dust outbreak episode, in particular on the role of atmospheric circulation transporting high amounts of dust toward Portugal in February 2017. In order to assess the atmospheric conditions behind the mineral dust layer observed in Évora from lidar observations, two simulations were performed with the Meso-NH model including dust emission but with different initializat...
VERTICALLY-RESOLVED CHARACTERIZATION OF THE FEBRUARY 2016 EXCEPTIONAL SAHARAN D...
Guerrero Rascado, Juan Luis; Costa, Maria João; Sicard, Michael; Gómez-Amo, J. L.; Benavent-Oltra, J. A.; Román, R.; Bortoli, Daniele; Marcos, C.An unusual Saharan dust outbreak occurred on 20-24 February 2016 over the Iberian Peninsula. This work focuses on the particle vertical distribution investigated at four EARLINET AERONET stations: Granada, Évora, Burjassot and Barcelona. This event was exceptional because: (i) Saharan dust outbreaks over the Iberian Peninsula are atypical during wintertime,(ii) the aerosol optical depth reached high values (up ...
