abstract = "The climatology of the moisture and heat budget equation terms for
subareas within the South American Monsoon System (SAMS) region is
investigated for the 1958-2014 period considering the distinct
phases of the Pacific Decadal Oscillation (PDO). These budget
equations are applied to the data from the National Centers for
Environmental Prediction (NCEP) Reanalysis project. Sources or
sinks of moisture and heat are equation residues, referred to as
residue and diabatic terms, respectively. Analyses are done for
the Central Amazon Basin (CAM) and Western-Central Brazil (WCB)
for three distinct periods, 1958-1976, 1977-1995, and 1996-2014,
that correspond to the cold, warm, and undefined PDO phases. The
differences among the PDO phases for each term are discussed. The
CAM region acts dominantly as a moisture sink and heat source in
all months during the three phases. On the other hand, in the WCB
region, the monsoon characteristics are better defined, with a
moisture sink (source) and a heat source (sink) during the wet
(dry) season. The main result of the present analysis is the
persistence of SAMS intensification signs in both CAM and WCB
areas up to the last analyzed period (1996-2014), which is
consistent with intense flooding in the Amazon Basin in 2008/2009,
2012, and 2014.",
