Numerical Simulations of Fog Events in Southern Portugal
Policarpo, Carlos; Salgado, Rui; Costa, Maria JoãoThis work aims at improving the knowledge on fog formation and its evolution in the Alentejo region (Portugal). For this purpose, brief regional fog climatology, essentially based on information from the Beja Air Base meteorological station, was produced and several numerical high resolution simulations were performed using the Meso-NH. The ECOCLIMAP database used to generate the model physiography was improved...

Salgado, Rui; Potes, Miguel; Albino, André; Apolinário, João; Barbosa, Susana; Bárias, Samuel; Beliche, Paulo; Bortoli, Daniel; Canhoto, PauloThe ALqueva hydro-meteorological EXperiment, ALEX 2014, was an integrated field campaign with measurements of chemical, physical and biological parameters in water and air at different experimental sites in the region of the Alqueva reservoir, a 250 km2 man made lake, in the southeast of Portugal. The Field campaign took place from June 1 to September 30, 2014 and comprises an Intensive Observation Period (IOP)...

Salgado, Rui; Potes, Miguel; Policarpo, Carlos; Le Moigne, PatrickThe ALqueva hydro-meteorological EXperiment, ALEX 2014, was an integrated field campaign (http://www.alex2014.cge.uevora.pt) with measurements of chemical, physical and biological parameters in water and air at the Alqueva reservoir, a 250 km2 man made lake, in the southeast of Portugal. The ALEX 2014 took place from June 1 to September 30, 2014 and includes an Intensive Observation Period (IOP) of three days (...
ALEX2014: The Alqueva Hydro-Meteorological Experiment
Salgado, Rui; Potes, Miguel; Albino, André; Apolinário, João; Barbosa, Susana; Bárias, Samuel; Beliche, Paulo; Bortoli, Daniel; Canhoto, PauloDuring the four months of the ALEX 2014, the over water fluxes of momentum, heat and mass (H2O and CO2) were obtained with an integrated Open-Path CO2 /H2O Gas Analyser and 3D Sonic Anemometer, mounted on a floating platform (Fig.1) belonging to the Portuguese Environment Agency. The short and long wave, up and down, radiative fluxes were measured at the same place, as well as the water temperature profile. Eig...
Numerical Simulations of Fog Formation and Evolution in Alentejo Region
Policarpo, Carlos; Salgado, Rui; Costa, Maria JoãoThe effect of fog on human life was recognized in the early ages of mankind but its impact has significantly increased during recent decades due to increasing air, marine, and road traffic. In fact, the financial and human losses related to fog and low visibility became comparable to the losses from other weather events, e.g., tornadoes or, in some situations, even hurricanes, mainly, because they occur more fr...
