             abstract = "Stratification and mixing patterns of a water body are influenced 
                         by the variability of atmospheric systems, which can also modify 
                         their biogeochemical properties. The primary goal of this study 
                         was to analyze the effect of atmospheric cold fronts (CFs) on 
                         thermal stratification and water quality parameters in 4 
                         embayments of the Furnas Hydroelectric Reservoir (FHR) 
                         (southeastern Brazil), a warm monomictic water body. A secondary 
                         goal was to evaluate the implications of this effect on the 
                         aquaculture of Nile tilapia Oreochromis niloticus (L.) in net 
                         cages. A 2 yr dataset of meteorological and water quality 
                         parameters was used to compute heat flux balance components and 
                         buoyancy frequency. These parameters were used to evaluate the 
                         influence of CFs on FHR water column stability and water quality. 
                         It was observed that the passing of CFs increased net heat loss 
                         and wind velocity, resulting in a partial mixture of surface 
                         waters with deeper layers. These changes in the physical structure 
                         of the water column altered the diel cycle of water temperature, 
                         led to a slight decrease in dissolved oxygen concentrations and pH 
                         values during the stratification period, and contributed to the 
                         increase in dilution power at the fish cultivation sites. However, 
                         following CF passages, no significant changes were observed in 
                         water quality parameters that influenced Nile tilapia cultivation 
                         in the FHR. Nevertheless, the understanding of meteorological 
                         systems and their influence on the physical and biogeochemical 
                         properties of an aquatic system is important for optimal 
                         management of aquaculture activities.",
