abstract = "Drought is documented in causing drawdowns of surface reservoirs
and impacting water supplies all over the globe. One such
documented case occurred in Southern Brazil, over the Cantareira
System (CS), one of the largest in the world, as well as one used
to supply 8.8 million customers, including metropolitan S{\~a}o
Paulo city. The March 2014 prolonged drought over the region
supplying the Cantareira System caused a drop in the reservoirs
down to 14.0% of their usable capacity, its lowest recorded level
since 1974, the year of commencement of operation. Southeastern
South America has a well-defined wet austral summer monsoon, with
a marked precipitation regime of more than 800 mm of accumulated
precipitation over the region, which was significantly curtailed
during the drought episode. The large-scale atmospheric and
oceanic patters are investigated to highlight the mechanisms
associated with the drought event. In this paper, we investigated
possible teleconnections of the capacity of the reservoir and sea
surface temperature at remote regions. The Standard Precipitation
Index (SPI), used to characterize the severity of precipitation
deficiency, illustrates the magnitude and spatial extent of the
interruption of precipitation supply. The paper concludes with an
analysis of the performance of the seasonal precipitation forecast
for December, January and February 2014 produced with the
operational seasonal prediction system used at the Center for
Weather Forecasts and Climate Studies of the National Institute
for Space Research (CPTEC/INPE).",
