The objective of this work is to analyze thespatio-temporal distribution of Global Horizontal Irradiation (GHI) on aregional scale and its relationship with frequent synoptic situations in thesouth of the Pampeana region (Argentina). It was verified that the latitudinal patternof distribution of the GHI is modified in the region by cloud cover, which isin turn determined by the seasonal dynamics of action centers and the passageof fronts in summer and winter. The South America Monsoon System (SAMS) definesdifferential situations of cloudiness and rainfall in the region, which affectGHI. GHI increased successively between the decades 1981?2010, a factorassociated with the variability of rainfall that characterizes the region.
