abstract = "The objective of this work is to determine the main modes of
precipitation variability over South America in different
frequency bands (interannual, interdecadal, intraseasonal and
synoptic) and their variation in many periods of time. A detailed
verification about modes variability from 1860 to 2100 will be
presented to show differences between current and past climate,
the main changes observed and what would be the main climate
expected. Moreover, it was also determined if the number of
extreme precipitation events (drier or wetter) experienced
significant changes. To this analysis the principal component
(PCA) of 30-years moving periods (1860-1890, 1870-1900, ...,
2070-2100) was calculated. Precipitation data from the coupled
atmosphere-ocean general circulation model (HadCM3) developed at
the Hadley Centre was used. This data has a resolution of 2.5°
(latitude) x 3.75° (longitude), producing a global grid of 96 x 73
grid cells, with a equivalent resolution of 417 km x 278 km at the
Equator, reducing to 295 km x 278 km at 45° of latitude
(comparable to a spectral resolution of T42).",
