Resumen

La ocurrencia de sequías anuales y plurianuales en la región semiárida brasileña es un fenómeno recurrente que desencadena una serie de consecuencias, con impactos en el medio ambiente y en la calidad de vida de la población que habita esa región. La Región Geográfica Inmediata de Monteiro - PB (REGIM), ubicada en la región semiárida de Paraíba, no difiere de esta realidad, considerando que se inserta en el polígono de
sequía. En vista de lo anterior, esta investigación tiene como objetivo correlacionar los Índices de Severidad de los Eventos de Sequía MD, IPN e IAC en REGIM, a través de datos de la serie histórica de precipitaciones, con el fin de clasificar datos cuantitativos a escala mensual y anual e identificar la Severidad de los Eventos (SDE) de estos ciclos y, así, evaluar la variación de la precipitación en el tiempo, identificando los períodos
seco y lluvioso. En el desarrollo de esta investigación, se utilizaron datos de precipitaciones mensuales de la Superintendencia de Desarrollo del Nordeste (SUDENE), el Instituto Nacional de Meteorología (INMET) y la Agencia Ejecutiva de Gestión Hídrica de Paraíba (AESA) para componer el espacio. la variabilidad temporal de la precipitación, que se calculó mediante el Índice de Porcentaje Normal - IPN (CUNHA, 2008), el Método
de Deciles - MD (GIBBS; MAHER, 1967) y el Índice de Anomalía de la Lluvia - IAC (ROOY, 1965). 

Palabras-clave: Índice de Estandarización de Lluvia – Ipp; Severidad de Eventos – SDE; Recursos Hídricos.
