                         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.",
