             abstract = "The present study sought to develop a methodology to analyse water 
                         quality based on the concepts and methods of climate and 
                         climatology. Accordingly, we attempted to relate hydro- and 
                         limnometeorological techniques and methodologies to a rhythmic 
                         analysis technique developed within the context of the Brazilian 
                         geographical climatology. Our goal was to assess and analyse 
                         cyanobacterial blooms, the main index of water quality for the 
                         reservoirs of the {"} Alto Tiet{\^e}{"} Basin and, consequently, 
                         the Metropolitan Region of S{\~a}o Paulo, an area of high 
                         environmental complexity due to its high degree of development and 
                         high population density. The meteorological data used were 
                         collected by the Institute of Astronomy, Geophysics and 
                         Atmospheric Sciences at the University of S{\~a}o Paulo 
                         meteorological station, and the limnological data were collected 
                         through the Hydrological Monitoring System implemented by SABESP 
                         in the Billings and Guarapiranga Reservoirs and the laboratory of 
                         the same entity. The rhythmic and integrated analysis showed that 
                         the process of cyanobacterial blooms is dependent on a combination 
                         of meteorological factors as temperature and wind intensity that 
                         may disrupt the stability of the reservoir, providing the 
                         conditions necessary for the development of cyanobacteria during 
                         the stabilisation process. The pace of the Atlantic Polar Front 
                         Entrance during the winter in S{\~a}o Paulo is a limiting factor 
                         for the growth of cyanobacteria because of their high frequency, 
                         thus maintaining the balance of the reservoir throughout this 
                         period. The weather types those could cause a instability in the 
                         water column were: Cold Front entrance (66.67%), conflict between 
                         masses (22.22%) and the Tropical Instability Line (11.11%). The 
                         possibility for prevention and forecasting periods advise when 
                         these reservoirs should not be used, mainly with regard to 
                         recreational activities.",
