abstract = "The State of S{\~a}o Paulo in Brazil experienced in 2014 and
early 2015 an expressive precipitation deficit, leading to drought
conditions with impacts in water availability for public
consumption, hydropower generation, and agriculture, particularly
during austral summer. This study performs a detailed diagnostics
of the observed precipitation during 2014 and early 2015 over a
particular region of S{\~a}o Paulo State, which includes the
massively populated metropolitan region of S{\~a}o Paulo. The
diagnostic was designed to provide answers to a number of relevant
questions for the activities, decisions, and strategic planning of
several sectors (e.g., general public, media, and high-level
governments). Examples of questions such diagnostics can help
answer are: How much precipitation has the region received? Has
the region experienced drought conditions in the past? When have
similar drought conditions been observed in the past? What has
been the observed precipitation pattern in the last years? How
severe/rare were the 2014 and 2015 droughts? When does the rainy
season typically start/end in the region? What happened during the
2013/2014 and 2014/2015 rainy seasons? The performed diagnostics
based on historical 1961/19622014/2015 records revealed that the
2013/2014 austral summer was a very rare event classified as
exceptionally dry. Similar drought events were previously recorded
but with smaller magnitude in terms of precipitation deficits,
making the 2013/2014 drought event the driest on the examined
record. In fact, the region has been experiencing a precipitation
deficit pattern since 1999/2000. One of the contributing factors
for the expressive precipitation deficit in 2014 was the
abnormally early end of the 2013/2014 rainy season in the
region.",
