The South Atlantic convergence zone (SACZ) is the main summer-typical atmospheric phenomenon occurring in South America, and it is of great interest because it regulates the rainy season in the most populated regions of Brazil. Frequency variability, per...

Intraseasonal (IS) variability in South America is efficiently described through the first empirical orthogonal function of filtered precipitation or outgoing longwave radiation (OLR) anomalies. In the 30?90-day band, the leading OLR pattern between Octo...

Several studies had shown that the anomalies of the sea surface temperature of the Tropical Atlantic and Pacific Oceans, are related to variations in the duration and timing of the rainy season in Central America. Cluster analysis was used to identify co...
