El objetivo de este estudio se basó en detectar las sequías meteorológicas en una región seco tropical de Venezuela. La información utilizada para el estudio se obtuvo del registro de datos meteorológicos, provenientes de series de precipitación mensual de la estación meteorológica “El Tigre Automática”, situada dentro del campo experimental del INIA del estado Anzoátegui, para el período 1971-2016.

The objective of this study was based on detecting meteorological droughts in a tropical dry region of Venezuela. The information used for the study was obtained from the meteorological data record, coming from monthly precipitation series of the meteorological station .El Tigre Autom´atica”, located within the experimental field of the INIA of the Anzo´ategui state, for the period 1971-2016. The Standardized Precipitation Index (SPI) was used for a monthly scale of the period under study, which allowed to identify and describe the drought phenomenon, specifying its intensity, duration, magnitude and frequency of occurrence.
According to the RLS values obtained, it was obtained that the level of intensity of extreme drought in the locality was very low (1.27 %), being few frequent with extremely strong magnitudes. These meteorological drought events occurred between the months of March and September. By virtue of the results obtained, the SPI from the precipitation data allowed to detect the drought events in the evaluated locality, thus managing to specify intensity, duration, magnitude and frequency of occurrence of these; which would allow to evaluate the vulnerability of the area to the effects of climate change.
