Part one: an observational analysis [Elektronische Daten] [M. F. Correia, M. A. F. da Silva Dias, M. R. da Silva Aragão] Summary: Sobradinho Lake lies in the São Francisco River Basin, in one of the most arid regions in Northeastern Brazil, within a land stretch categorized as the Lower-middle São Francisco, situated at about 40 km away from the municipality of Petrolina (09°23′S-40°30′W) in the state of Pernambuco. The dam, in its full capacity, consists of a lake of approximately 4,214 km2; 280 km in length, the width of which varies from 5 to 50 km. The dam storage capacity is that of 34.1 billion m3 of water. Being situated in a semi-arid region, the dam brought about significant development to local irrigated agriculture. The caatinga ecosystem has, for that matter, undergone considerable changes. Statistical analysis techniques applied to data collected before and after the filling of the lake, made it possible both to make an assessment of the impact of the dam construction on the region meteorology and to diagnose the variability of such an impact on environmental conditions. Results showed that the dam has brought about considerable changes to regional meteorology. The alterations were observed to be more significant as regards atmospheric humidity and wind speed.
