abstract = "This study discusses the climatological aspects of the most severe
drought ever recorded in the semiarid region Northeast Brazil.
Droughts are recurrent in the region and while El Nino has driven
some of these events others are more dependent on the tropical
North Atlantic sea surface temperature fields. The drought
affecting this region during the last 5 years shows an intensity
and impact not seen in several decades in the regional economy and
society. The analysis of this event using drought indicators as
well as meteorological fields shows that since the middle 1990s to
2016, 16 out of 25 years experienced rainfall below normal. This
suggests that the recent drought may have in fact started in the
middle-late 1990s, with the intense droughts of 1993 and 1998, and
then the sequence of dry years (interrupted by relatively wet
years in 2007, 2008, 2009 and 2011) after that may have affected
the levels of reservoirs in the region, leading to a real water
crisis that was magnified by the negative rainfall anomalies since
2010.",
