abstract = "Precipitation is one of the most important climatic variables in
the Caatinga biome that influences the spatial and temporal
distribution pattern of its vegetation types. These types in turn
influence the regional climate from the feedback mechanism of
energy flows, water and momentum. This climate-vegetation
interaction in the Caatinga is differentiated depending on the
type of climate pattern in the region. This study aims to find out
how the annual precipitation pattern influence the vegetation
seasonality by the identification of the main phenological
features of the vegetation annual growth cycles and the annual
rainfall features in a gradient of five climatic regions in the
Caatinga biome. We use time series (2001-2008) of vegetation
indices such as NDVI and LSWI, and precipitation that was derived
of TRMM satellite data and surface station data. The results
indicate that precipitation variability in the rainy season
influences directly the variability of vegetation growing cycles.
That influence is not linear, but adjusted to a logarithmic
function being precipitation better fit with LSWI (r2 = 0.67) than
NDVI (r2 = 0.54). The influence of precipitation on Caatinga
vegetation, using phenological metrics such as start, end, peak
and length of the vegetation growing cycles, showed greater lag in
climatic regions with higher precipitation while in regions with
lower precipitation this lag was slight.",
