abstract = "El Niņo is a natural phenomena that causes severe drought in
Brazil's semi-arid, which can to develop desertification
processes. The objective of this study was to evaluate the
influence of El Niņo 2009/2010 period by answering the monthly
aridity index. The study area consisted of four watersheds ranging
between centers of desertification: Serid{\'o} (RN-Brazil) and
Cariris-Velhos (PB-Brazil). The aridity index was generated on a
monthly basis from 2008 to July 2013, using remote sensing images
from the MOD16 product (Modis) and interpolations of
meteorological stations. We used data from Worldclim (years
1950-2000) for comparative purposes. It was noted that El Niņo has
great influence on the prolonged decline in the indices of
aridity, being more prominent in north and west watersheds ratios
of the study area . The return of the index values of historic
drought was not detected in the period analyzed. We found
concentrated areas with aridity index values below of the
historical averages aridity index. These areas did not correspond
to the areas of the Spots of Desertification recognized by
government. The effect of El Niņo by the indices of aridity
identified the susceptibility of the region to this phenomenon and
inferring new areas susceptible to desertification.",
