abstract = "Moisture and heat budgets in selected areas of the South American
monsoon system (SAMS) and the equatorial Atlantic are examined for
the 19792006 period. These areas are the Central Amazon (CAM),
western Central Brazil (WCB), South Atlantic convergence zone
(SACZ) and the Atlantic inter-tropical convergence zone (ITCZ).
The moisture and heat budget terms are calculated using daily
reanalyzed data, and filtered for the 0.41.2 year scale. Analyses
are based on the correlation maps between these terms and the
expansion coefficient of the SAMS mode, previously identified. The
vertical structures of the moisture and heat budget terms are
discussed and allow us to examine the thermodynamic reasoning of
the SAMS relationship with the Atlantic ITCZ. Important
differences in the moisture and heat budgets have been found among
the analyzed areas. Except for the horizontal advection of q and
T, indications of a wet and dry season appear in the anomalies of
other terms 4 pentads earlier in the WCB than in the CAM. The SAMS
and the ITCZ relate to each other through the moisture and heat
budgets. A time lag of approximately 8 pentads is noted for the
moisture sink (source) and heat source (sink) between the CAM and
ITCZ regions during the wet (dry) season of both regions. Indeed,
the largest negative (positive) values of the residue term and the
largest positive (negative) values of the diabatic term occur at
pentad 12 (44) for the CAM and at pentad 20 (52) for the ITCZ. The
results here provide observational support to the relationship
between the SAMS and the Atlantic ITCZ. Copyright © 2010 Royal
