             abstract = "The passage of meteorological systems such as cold fronts or 
                         convergence zones over reservoirs can cause significant 
                         modifications in several aquatic variables. Cold fronts arising 
                         from Antarctic and reaching the southeast Brazil region modify the 
                         wind field basic and have important impact over physical, chemical 
                         and biological processes that act in the hydroelectric reservoirs. 
                         During the winter time these cold fronts can reach southeast 
                         Brazilian coast each six days and summer each fourteen days in 
                         average. Most part of them reaches interior of S{\~a}o Paulo, 
                         Minas Gerais and Goi{\'a}s States. Thus, the objective of this 
                         work is to analyze the influence of cold fronts passage in the 
                         thermal stratification and water quality of the Itumbiara 
                         (Goi{\'a}s, Brazil) hydroelectric reservoir. The characterization 
                         of the cold front passage over study area the GOES satellite 
                         images was used. To reach this objective a collection o 
                         meteorological (wind direction and intensity, short-wave 
                         radiation, air temperature, relative humidity, atmospheric 
                         pressure) and water temperature in four depths (5, 12, 20 and 40 
                         m) data were used. These data were collected using an Integrated 
                         System for Environmental Monitoring called SIMA, in high 
                         frequency, 1 hour. The stratification was assessed by 
                         non-dimensional parameter analysis. The Lake Number an indicator 
                         of the degree of stability and mixing in the reservoir was used in 
                         this analysis. It was possible to observe the influence of cold 
                         fronts on meteorological and also the thermal structure of the 
                         reservoir.",
