O impacto do El Niño sobre as precipitações de municípios do Sertão Paraibano.

Abstract

The present research aimed to assess whether there is correlation between the equatorial Pacific SST and precipitation in different municipalities of the sertão of Paraíba. Precipitation data was used from 1994 to 2015 of 19 seasons. It was performed a climatology with 22 years and it was rainy and dry periods and correlation was obtained between the data of precipitation and SST values of the areas of the Niño's. The main findings were that the rainy season in most stations covers the months from January to may and in years of El Niño events, precipitation tend to be below average and the area of the equatorial Pacific Ocean that most correlates with the rains of the Outback is Niño 4.
