Abstract

The parameters determining the rainfall, as the Number of Days of Rain (NDR), are of great importance in geographical and environmental studies, seeking a better understanding of the climate of a region. In order to analyze the NDR monthly and yearly in the state of Goiás, performed a study of its trend over time and its correlation with the extreme El Niño Southern Oscillation when this is with moderate or heavy. We used monthly and annual averages of the NDR of the time series of rainfall data obtained from the National Hydrometeorological Network, the National Water Agency of Brazil and the Geological Survey of Brazil. The final result for the period of 30 years of data studied, we found that there was a trend of decreasing NDC annual average of -6.1% in Goiás.

Key words: NDR, La Niña, El Niño, ENSO, rainfall.
