abstract = "The intra-seasonal variability of the precipitation associated
with the South America monsoon system (SAMS) are investigated for
a 30-yr period. The active and break periods of the monsoon were
determined by the criterion based on a monsoon rainfall index
(MRI) for the three wettest months applied to the West-Central
Brazil region. Using the MRI 71 (46) cases of monsoon break
(active) were identified. For active cases the precipitation
composite shows a similar pattern to average summer rainfall, but
with values exceeding 16mm over some areas of West-Central Brazil
region and the wind circulation composite present a strong
northwesterly flow from the western Amazon to southeastern Brazil.
Composite anomaly pattern shown that active period is associated
with 850-hPa northwesterly wind anomalies which converge in
central Brazil. However, break periods are associated with wind
anomalies from east to west over central Brazil.",
