abstract = "The climate in the Caatinga, especially precipitation, influences
the pattern of spatial and temporal distribution of the vegetation
that in turn influences 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 climatic pattern in the region. The
objective of this work is to identify the main phenological
features of the annual growth cycles of vegetation and
characteristics of the seasonal rainfall in 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 the best fit with the index LSWI (r2 = 0.67) than
with NDVI (r2 = 0.54). The influence of precipitation on
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 in the Caatinga
region.",
